How it works
Treat the internal bore as a cylinder: volume = π × (internal diameter / 2)² × length. Convert cubic metres to litres.
Input definitions
- Internal diameter (mm)
- Enter the value in the labeled unit.
- Pipe length (m)
- Enter the value in the labeled unit.
A worked example
- Internal diameter (mm)
- 100
- Pipe length (m)
- 10
Assumptions & limits
Use consistent stated units. Ideal geometric or physical model; verify dimensions and applicability before real-world design.

Common questions
Should I use the pipe outside diameter?
No. Enter the actual internal diameter. Wall thickness reduces internal capacity and nominal pipe sizes may not equal the measured bore.
How does Pipe internal capacity work?
Treat the internal bore as a cylinder: volume = π × (internal diameter / 2)² × length. Convert cubic metres to litres.
What are the limits of Pipe internal capacity?
Use consistent stated units. Ideal geometric or physical model; verify dimensions and applicability before real-world design.
