Pipe Weight Calculator
Calculate the weight of pipes by dimensions.

inches
feet
Weight = (OD² - ID²) × 0.7854 × Length × Material Density
Example: 20 ft of 2in Schedule 40 steel pipe = 67.6 lbs. Same length in aluminum = 22.8 lbs (70 percent lighter)
How is pipe weight calculated?
Weight = (OD² - ID²) × 0.7854 × Length × Material Density. This calculates the cross-sectional area of the metal times length times density.
What is schedule in pipe sizing?
Schedule (like SCH 40, SCH 80) indicates wall thickness for a given diameter. Higher schedule = thicker wall = heavier pipe.
Why does material matter for weight?
Different materials have different densities. Steel is about 3x heavier than aluminum, so an aluminum pipe of the same dimensions weighs 1/3 as much.
