Steel Pipe Weight Calculator
Pipe weight from OD and wall — the universal (OD−t)×t×0.0246 formula.
The mean-diameter trick: π×(OD−t)×t is the exact annulus area. 4-inch Sch 40 = 16.1 kg/m, matching ASME B36.10 to the decimal.

Steel Pipe Weight Calculator is a free pipe weight calculator for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Steel Pipe Weight Calculator
Pipe weight from OD and wall — the universal (OD−t)×t×0.0246 formula. The calculation implements kg/m = (OD − t) × t × 0.02466 (ASME B36.10M / IS 1239 weight tables). The mean-diameter trick: π×(OD−t)×t is the exact annulus area. 4-inch Sch 40 = 16.1 kg/m, matching ASME B36.10 to the decimal.
