Piping calculator
Pipe weight calculator
Estimate theoretical pipe weight from outside diameter, wall thickness, length and material.
Weight per metre—kg/m
Total weight—kg
Internal diameter—mm
Theoretical estimate. Actual product weight may vary because of manufacturing tolerances, coating and material density.
FAQ
Common questions
How is pipe weight calculated?
The calculator uses the annular cross-sectional area of the pipe multiplied by material density and length. It is a theoretical estimate.
What density is used for carbon steel?
The default carbon-steel density is 7,850 kg/m³. Stainless steel uses 7,930 kg/m³ in this calculator.
Why can actual pipe weight differ?
Manufacturing tolerances, coating, actual chemistry and dimensional tolerances can change the real weight. Use mill data for final shipping or structural calculations.
