Instant · runs in your browserAbout the Pipe Volume Calculator
Calculate how much liquid a pipe holds from its internal diameter and length. Results are shown in cubic units, litres and gallons, which is useful for plumbing, irrigation and heating systems.
Formula
Volume = π × (inner diameter ÷ 2)² × length.
Tip
Use the inside diameter, not the outside; pipe walls can make a big difference on small pipes.
