Enter pipe dimensions to calculate volume and weight…
Calculates internal/external pipe volume, fluid capacity, and material weight. Supports imperial & metric units. Real‑time, step‑by‑step, with 3D preview.
The Pipe Volume Calculator is a simple yet powerful online tool that helps you find the volume, capacity, or internal space of a pipe based on its dimensions. Whether you’re an engineer, plumber, or DIY enthusiast, this tool makes it easy to calculate how much liquid, gas, or material a pipe can hold.
At GCalculate.com, our Pipe Volume Calculator provides accurate, instant results — helping you save time and avoid manual math errors.
A Pipe Volume Calculator determines the internal volume of a cylindrical pipe based on its inner diameter and length. This is especially useful for:
Estimating fluid capacity in water or gas pipes
Planning chemical or oil transport
Designing plumbing or irrigation systems
Calculating pipe storage or flow rates
By knowing the pipe volume, you can calculate how much fluid it can carry, how long it takes to fill or drain, and even the pressure changes in different sections.
The tool uses the cylinder volume formula:
V=π×r2×hV = \pi \times r^2 \times h
Where:
V = Volume of the pipe
π (pi) = 3.14159
r = Inner radius of the pipe (half the inner diameter)
h = Length of the pipe
The result gives you the volume in cubic units (e.g., cubic meters or cubic inches). The calculator can also convert it to liters, gallons, or milliliters depending on your needs.
Suppose you have a steel pipe with an inner diameter of 10 cm and a length of 2 meters.
r=10/2=5 cm=0.05 m
V=π×(0.05) 2 ×2=0.0157 m³
Converting cubic meters to liters:
0.0157×1000=15.7 liters
So, the pipe can hold approximately 15.7 liters of water.
The Pipe Volume Calculator from GCalculate.com takes the guesswork out of fluid measurement. Whether you’re estimating water storage, designing pipe systems, or calculating material requirements, this calculator provides accurate, quick, and reliable results. Use it today to make your engineering, plumbing, or industrial projects smoother and more efficient.
It calculates the internal volume of a pipe to determine how much liquid or gas it can hold.
You can use metric (mm, cm, m) or imperial (inches, feet) units — results are shown in cubic meters, liters, or gallons.
You’ll need the inner diameter and length of the pipe.
The material doesn’t affect the internal volume directly, but it may influence the inner diameter due to wall thickness.
