# Pipes with Water Content - Weight and Volume

## Estimate water content in pipes - weight and volume.

*1 lb/ft = 1.49 kg/m**1 gal(US)/ft = 12.4 liter/m*

Note that for most pipes Nominal Size **is not** equal to inside diameter. For exact volumes - check the pipe documentation or standard - and use the calculator below.

The volume weight for other liquids can be calculated when compensated for density.

### Example - Water Content in Pipe

The water volume in a *12 m* long *2"* pipe can be calculated as

* (2.0 liter/m) (12 m) *

*= 24 liter*

### Pipes - Volume Calculator

This calculator can be used to calculate volume of water or other liquids in pipes. The calculator is generic and can be used for any units as long as the use of units are consistent. If input is *m* the result is *m ^{3}/m* and so on.

*Inside diameter of pipe (m, mm, ft, in ...)*

Use the volume converter in the left column for other units.
