The Pipe Volume Calculator is a fast, accurate tool designed to calculate the internal volume of cylindrical pipes. It’s useful for estimating the capacity of pipes in plumbing, irrigation, construction, HVAC, and industrial systems.
Use this tool when you need to determine how much liquid or gas a pipe can hold, whether you're installing water lines, calculating fluid transport volumes, or estimating storage capacity.
You can enter dimensions in inches, feet, millimeters, or centimeters. The volume output is available in liters, gallons (US and UK), cubic meters, and cubic feet.
Pipe Volume Formula
Formula:
Volume = π × (Inner Radius)² × Length
Explanation:
- π (Pi) is approximately 3.1416
- Inner radius is half the internal diameter of the pipe
- Length is the total length of the pipe (in the same unit as radius)
Example:
A pipe with an internal diameter of 10 cm (radius = 5 cm) and a length of 200 cm:
Volume = 3.1416 × (5²) × 200 = 3.1416 × 25 × 200 = 15,708 cm³ = 15.7 liters

FAQs
Q: How do you calculate volume of a pipe?
A: Use the formula Volume = π × (inner radius)² × length. This calculator handles it for you—just enter the diameter and length.
Q: What units does this calculator support?
A: You can input length and diameter in inches, feet, mm, or cm. Output volume is shown in liters, gallons (US & UK), cubic meters, and cubic feet.
Q: Can I use this calculator for PVC or steel pipes?
A: Yes, this tool works for any cylindrical pipe—PVC, steel, copper, plastic, etc.—as long as the internal diameter is known.
