How to use it
- Enter inner diameter in meters.
- Enter pipe length in meters.
- Calculate cubic meters, liters and oil-barrel equivalents.
Pipeline Volume Calculator
Calculate the geometric internal volume of a straight circular pipe segment.

About the Pipeline Volume Calculator
This calculator treats a pipe segment as a straight circular cylinder using entered internal dimensions.
Formula
Volume = π × (inner diameter ÷ 2)² × length.
Example
A 0.5 m inner diameter over 100 m has an ideal geometric volume near 19.635 m³.

Fittings, wall geometry, deposits, elevation, pressure, fluid properties and operating conditions are excluded. This is not pipeline design or pressure-safety guidance.
