Pipe Volume Calculator
Inner Diameter (cm)
Length (m)
A pipe volume calculator finds the internal fluid volume of a cylindrical pipe from its inner diameter and length. Used in plumbing, HVAC, and chemical engineering.
- 1Volume = π × (d/2)² × length
- 2Use inner diameter, not outer
- 3Keep units consistent (all metres)
- 4Multiply m³ × 1,000 for litres
Inner diameter 5cm, length 8m=V = π × 0.025² × 8 = 0.01571 m³ = 15.71 litres
| Inner diameter | Litres/metre |
|---|---|
| 15mm | 0.18 L/m |
| 22mm | 0.38 L/m |
| 28mm | 0.62 L/m |
| 50mm | 1.96 L/m |
| 100mm | 7.85 L/m |
