Pipe Weight Calculator — Unit Weight of Empty Pipes
This calculator supports calculations for pipe weight in both kg/m and kg/ft, making it suitable for both European and US standards. The underlying formulas and material densities are based on established standards; please contact us if you have any questions.
The formula is as follows:
Pipe Cross-section：
This formula applies to carbon steel pipes, stainless steel pipes, alloy steel pipes, and similar types. A reference table for the densities of various pipe materials is provided at the bottom of this page.

Steel Pipe Industry Pipe Weight Calculator
In the steel pipe industry, the most commonly used formula for calculating pipe weight is:
W = 0.02466 × t × (D − t)

Where:
· W = kg/m
· D = Outer diameter (mm)
· t = Wall thickness (mm)

SCH 80 Pipe Weight Calculation Example
- NPS：6″
- OD：168.3 mm
- SCH 80 Wall Thickness：10.97 mm
- Steel Density：7850 kg/m³
- Formula：
W=0.02466×t×(D−t)W = 0.02466 \times t \times (D – t)
W=0.02466×10.97×157.33≈42.57kg/m
