How the Pipe Weight Calculator Formula Works
A pipe is a ring of metal, so its weight per length is the area of that ring times the density of the material. The ring area is pi/4 × (OD squared - ID squared), where the inside diameter is the outside diameter minus twice the wall thickness. For steel at 7,850 kilograms per cubic metre this simplifies to 10.69 × (OD - t) x t pounds per foot with sizes in inches, or 0.02466 × (OD - t) x t kilograms per metre with sizes in millimetres.
For standard pipe you do not need to measure. Choose the nominal pipe size and the schedule, and the calculator takes the outside diameter and wall thickness from the ASME B36.10M and B36.19M tables. NPS 4 Schedule 40, for example, is 4.5 inches across with a 0.237 inch wall, which weighs 10.80 pounds per foot. Square and rectangular tube use the wall area, width x height minus the inside rectangle.
Multiply by the length and the number of pieces for the total. The inside area times the density of water adds the weight of a pipe full of water. A different material changes only the density, so aluminium is about a third of the weight of steel.
weight per length = density × pi/4 × (OD2 − ID2); steel, lb/ft = 10.69 × (OD − t) × t (inches); steel, kg/m = 0.02466 × (OD − t) × t (mm)- ODin or mmOutside diameter of the pipe, or the outside width of a tube.

A Real Worked Example
Choose NPS 4 and Schedule 40, carbon steel, one piece 20 feet long. The table gives a 4.5 inch outside diameter and a 0.237 inch wall, so the inside diameter is 4.026 inches.
The weight is 10.802 pounds per foot, 16.075 kilograms per metre. The 20 foot piece weighs 216.0 pounds, 98.0 kilograms. Full of water it is 326.4 pounds.
Line pipe: NPS 12 standard wall, 40 ft joint
Choose NPS 12 and STD, one piece 40 feet long. The outside diameter is 12.75 inches and the wall is 0.375 inch. The weight is 49.615 pounds per foot, 73.835 kilograms per metre.
The joint weighs 1,984.6 pounds, 900.2 kilograms, and 3,946 pounds full of water. Coating and end finishing are not included.
Metric round pipe, 60.3 x 3.91 mm, 6 m
Choose metric units and a round pipe with a 60.3 mm outside diameter and a 3.91 mm wall, one piece 6 metres long. The metal area is 6.927 square cm.
The weight is 5.437 kilograms per metre, so the 6 metre length weighs 32.6 kilograms, 71.9 pounds. With water inside it is 45.6 kilograms.
Aluminium pipe, 2 in OD with a 0.25 in wall, three 10 ft pieces
Choose a round pipe in inches, aluminium, with a 2 inch outside diameter and a 0.25 inch wall, three pieces of 10 feet. The weight is 1.609 pounds per foot.
The three pieces weigh 48.3 pounds, 21.9 kilograms. The same size in carbon steel would be 4.678 pounds per foot.
Square steel tube, 50 x 50 x 3 mm, 6 m
Choose metric units and a square tube with a 50 mm side and a 3 mm wall, 6 metres long. The metal area is 50 × 50 − 44 × 44 = 564 square mm, 5.64 square cm.
The weight is 4.427 kilograms per metre, so the length weighs 26.6 kilograms. Real tube has rounded corners, so published tables show a slightly lower figure.
Rectangular steel tube, 100 x 50 x 4 mm, two 6 m lengths
Choose metric units and a rectangular tube 100 by 50 mm with a 4 mm wall, two pieces of 6 metres. The metal area is 100 × 50 − 92 × 42 = 1,136 square mm.
The weight is 8.918 kilograms per metre, so the two lengths weigh 107.0 kilograms, 235.9 pounds.
What Else to Know
How Pipe Weight Is Calculated
Pipe weight is the metal volume times the density. The metal sits in a ring, so the cross-section area is pi/4 × (OD squared - ID squared), with the inside diameter equal to the outside diameter minus twice the wall thickness. Multiply by the length and the density.
For carbon steel this gives the familiar shortcuts: 10.69 × (OD - t) x t pounds per foot with sizes in inches, and 0.02466 × (OD - t) x t kilograms per metre with sizes in millimetres. The calculator works from the density directly, 7,850 kilograms per cubic metre for carbon steel, so it handles other materials too.
The ring area comes from the standard formula for an annulus.
Steel Pipe Weight Chart by NPS and Schedule
Standard pipe is ordered by nominal pipe size and a schedule. NPS is a name, not a measured diameter: NPS 2 pipe has a 2.375 inch outside diameter. The schedule sets the wall, and a higher schedule means a thicker wall and a heavier pipe.
The calculator holds the outside diameter and wall thickness for NPS 1/8 to 24 from the ASME B36.10M and B36.19M dimension tables, as printed in the Wikipedia article on nominal pipe size. STD equals Schedule 40 up to NPS 10 and XS equals Schedule 80 up to NPS 8. Above those sizes the walls differ.
The Schedule 40 and Schedule 80 charts list pounds per foot and kilograms per metre.
Line Pipe Weight Calculator and Plain-End Weight
A line pipe weight calculator needs the outside diameter, the wall thickness and the length. Pick the NPS and schedule for standard sizes, or enter your own OD and wall for any line pipe. The result is the plain-end weight of the pipe body.
Threads, couplings, welds, coatings and mill tolerances change the real weight, so use the manufacturer's data for purchasing and lifting plans. The comparison table sets the calculator against the weights printed in the ASME table: within about 0.2 percent, because the printed values use a steel density about 0.1 percent lower than 7,850 kilograms per cubic metre.
For a spreadsheet, use =PI()/4*((OD/1000)2-((OD-2*t)/1000)2)*7850 for kilograms per metre.
Weight per Meter, in kg and lbs
Choose metric units and enter the diameter and wall in millimetres to read kilograms per metre and total kilograms. The imperial results appear beside them: pounds per foot and total pounds, with short tons for large orders.
To convert, one kilogram per metre is 0.671969 pounds per foot, and one kilogram is 2.20462 pounds. The metric chart lists common outside diameters and walls with the weight of a 6 metre length.
Set the number of pieces to get the weight of a bundle or a truck load.
Square and Rectangular Tube Weight
Square and rectangular hollow sections have wall area equal to the outer rectangle minus the inner one, which the calculator multiplies by the density. Choose square or rectangular, then enter the outside sizes and the wall.
Hollow structural sections have rounded corners, with a radius of about twice the wall thickness, so the sharp-corner calculation is a little high. Use it as a close estimate and a published section table for design values. The square and rectangular tables list common sizes and walls.
The wall must be less than half the shorter side.
Other Materials and Water-Filled Weight
Density sets the weight. The calculator offers carbon steel, stainless steel, aluminium, copper, brass, PVC and HDPE, or your own value. The material table shows one pipe in each. Densities follow the Wikipedia pages for density, stainless steel, PVC and HDPE.
A pipe in service may be full of water. The calculator adds the inside volume times 1,000 kilograms per cubic metre to give the full weight per foot and in total, which matters for hangers and supports.
Stainless pipe sizes in the standard tables use the B36.19M schedules, so check the wall of the product you buy.
Limits and Related Calculators
The result is an estimate of plain-end weight for a pipe of perfect dimensions. Real pipe has tolerances on diameter and wall, and manufacturers publish nominal weights. Do not use the estimate alone to design supports, lifting or pressure systems: follow the applicable code and have a qualified engineer check the work.
To express a tolerance as a share of weight, the percentage calculator helps. To estimate a weight between two table sizes, the linear interpolation calculator does the arithmetic.

| Using steel density for aluminium | About 2.9 times too heavy | Choose the right material |
| Forgetting water inside | Supports undersized for a full pipe | Check the water-filled weight |
| Counting threads or coating as part of the weight | Small difference | Add manufacturer data for coatings and couplings |
Frequently Asked Questions About the Pipe Weight Calculator
How do you calculate pipe weight?
Multiply the metal cross-section area by the density and the length. The area of a round pipe is pi/4 × (OD2 - ID2). For steel pipe in inches, weight in pounds per foot is about 10.69 × (OD - wall) x wall. NPS 4 Schedule 40, with a 4.5 inch OD and 0.237 inch wall, comes to 10.80 lb per foot. Enter your own size, material and length in the calculator for an exact answer.
How do I use a line pipe weight calculator?
Line pipe is sized by outside diameter and wall thickness, so enter those, or pick the NPS and schedule, then the length. The result is the plain-end weight. NPS 12 standard wall line pipe weighs 49.61 lb per foot, so a 40 ft joint is 1,985 lb. Coating and threads add more. Enter your own size, material and length in the calculator for an exact answer.
What is the formula for steel pipe weight per foot?
W (lb per foot) = 10.69 × (OD - t) x t, with OD and wall t in inches. It is the area pi x (OD - t) x t of the wall times the density of steel, 0.2836 pounds per cubic inch, times 12 inches. For OD 2.375 and t 0.154 it gives 3.66 lb per foot. Enter your own size, material and length in the calculator for an exact answer.
How do I calculate pipe weight per meter?
For steel with OD and wall t in millimetres, kg per metre = 0.02466 × (OD - t) x t. A 60.3 mm pipe with a 3.91 mm wall is 0.02466 × 56.39 × 3.91 = 5.437 kg per metre. The calculator uses the density 7,850 kg per cubic metre and gives 5.437. Enter your own size, material and length in the calculator for an exact answer.
How do I calculate the weight of steel?
Weight = volume x density. Carbon steel is about 7,850 kg per cubic metre, which is 490 pounds per cubic foot. For a pipe, the volume is the metal area times the length. One metre of pipe with 20.48 square cm of metal weighs 16.07 kg. Enter your own size, material and length in the calculator for an exact answer.
How much does Schedule 40 pipe weigh?
It depends on the size. Schedule 40 steel pipe weighs about 0.85 lb per foot for NPS 1/2, 3.66 for NPS 2, 10.80 for NPS 4, 18.99 for NPS 6 and 53.58 for NPS 12. The Schedule 40 chart lists more sizes. Enter your own size, material and length in the calculator for an exact answer.
How much does Schedule 80 pipe weigh?
Schedule 80 has a thicker wall. Steel pipe weighs about 1.09 lb per foot at NPS 1/2, 5.03 at NPS 2, 15.00 at NPS 4, 28.60 at NPS 6 and 88.60 at NPS 12. NPS 4 is 39 percent heavier than Schedule 40. Enter your own size, material and length in the calculator for an exact answer.
What is the difference between Schedule 40 and Schedule 80?
Both have the same outside diameter for a given size, but Schedule 80 has a thicker wall, so it is heavier, stronger and has a smaller bore. For NPS 4 the wall is 0.237 inch at Schedule 40 and 0.337 inch at Schedule 80, and the bore falls from 4.026 to 3.826 inches. Enter your own size, material and length in the calculator for an exact answer.
What do STD, XS and XXS mean?
They are the older standard, extra strong and double extra strong wall names. STD is the same as Schedule 40 up to NPS 10, and XS the same as Schedule 80 up to NPS 8. Above those sizes they are separate wall thicknesses, so choose the exact one in the calculator. Enter your own size, material and length in the calculator for an exact answer.
What does a 4 inch steel pipe weigh?
NPS 4 has a 4.5 inch OD. Schedule 40 weighs 10.80 lb per foot, 16.07 kg per metre, so a 20 ft length is 216 lb. Schedule 80 weighs 15.00 lb per foot. These are plain-end weights. Enter your own size, material and length in the calculator for an exact answer.
How do I convert steel weight from kg to lbs?
Multiply kilograms by 2.20462. A pipe at 16.075 kg per metre is 35.44 lb per metre, or 10.80 lb per foot. The calculator shows kg per metre, lb per foot and total weight in both. Enter your own size, material and length in the calculator for an exact answer.
How much does stainless steel pipe weigh?
Stainless steel is denser than carbon steel, about 8,000 kg per cubic metre against 7,850, so a pipe is about 1.9 percent heavier. A 60.3 × 3.91 mm pipe is 5.541 kg per metre in stainless. Exact density varies with the alloy. Enter your own size, material and length in the calculator for an exact answer.
How much does aluminium pipe weigh?
Aluminium is about 2,700 kg per cubic metre, roughly a third of steel. A 60.3 × 3.91 mm pipe weighs 1.870 kg per metre against 5.437 in steel. Choose aluminium in the material list. Enter your own size, material and length in the calculator for an exact answer.
How do I find MS pipe weight?
MS is mild steel, density about 7,850 kg per cubic metre, which is the calculator's carbon steel default. A 48.3 mm OD pipe with a 3.68 mm wall weighs 4.05 kg per metre. Enter the diameter and wall in millimetres, or pick an NPS and schedule. Enter your own size, material and length in the calculator for an exact answer.
How do I calculate square pipe weight?
A square tube of side a and wall t has metal area a2 − (a - 2t)2. A 50 mm tube with a 3 mm wall has 564 square mm, so 4.43 kg per metre in steel. Choose the square tube option. Rounded corners make real tube slightly lighter. Enter your own size, material and length in the calculator for an exact answer.
What is rectangular hollow section weight per meter?
The metal area is width x height minus the inside rectangle. A 100 × 50 mm tube with a 4 mm wall has 1,136 square mm, so 8.92 kg per metre in steel. The rectangular table lists common sizes and walls. Enter your own size, material and length in the calculator for an exact answer.
How do I calculate HSS steel weight?
HSS corners are rounded, with an outer radius of about twice the wall, so the true area is a little smaller than the sharp-corner formula. The calculator's square and rectangular options give a close upper estimate: 4.43 kg per metre for 50 × 50 × 3. Use a published HSS table for design values. Enter your own size, material and length in the calculator for an exact answer.
Is there a pipe weight calculator for Excel?
Yes, use a formula. For steel in kilograms per metre with OD and wall in millimetres: =PI()/4*((OD/1000)2-((OD-2*t)/1000)2)*7850. Multiply by the length and the number of pieces. For OD 60.3 and t 3.91 it returns 5.437, the same as this calculator. Enter your own size, material and length in the calculator for an exact answer.
How do I find the weight of a water-filled pipe?
Add the water to the pipe. Water is about 1,000 kg per cubic metre, 62.4 pounds per cubic foot. NPS 4 Schedule 40 weighs 10.80 lb per foot empty and 16.32 lb per foot full. The calculator shows both. Enter your own size, material and length in the calculator for an exact answer.
Does the weight include threads and coating?
No. The result is the plain-end weight of the pipe body. Threads, couplings, welds, linings and coatings add weight, and mill tolerances on wall thickness change it a little. For purchasing or lifting plans, use the manufacturer's data and add a margin. Enter your own size, material and length in the calculator for an exact answer.
How close is it to the ASME B36.10M table?
Within about 0.2 percent. The printed weights use a steel density about 0.1 percent lower than 7,850 kilograms per cubic metre, so the calculator runs slightly high. The comparison table shows 12 sizes next to the printed weights from the standard's table. Enter your own size, material and length in the calculator for an exact answer.
How many pipes make a ton?
Divide 2,000 pounds by the weight of one length. A 20 ft NPS 4 Schedule 40 pipe weighs 216 lb, so a short ton is 9.3 pipes. For a metric tonne, divide 1,000 kg by the kilograms per length. Enter your own size, material and length in the calculator for an exact answer.
