About the Volume Calculator
This Volume Calculator is a versatile tool designed to determine the capacity of various geometric shapes. Whether you are filling a swimming pool, shipping a package, or estimating concrete for a project, knowing the volume is essential.
The calculator supports multiple input units (Metric and Imperial) and automatically converts the results into useful measurements like liters and gallons.
Common Formulas
- Cube: Volume = side³
- Rectangular Tank (Cuboid): Volume = Length × Width × Height
- Cylinder: Volume = π × r² × h
- Sphere: Volume = (4/3) × π × r³
- Cone: Volume = (1/3) × π × r² × h
Real World Uses
- Shipping & Logistics: Calculating dimensional weight for boxes and cargo.
- Construction: Estimating concrete, soil, or gravel needs (often in cubic yards). See our Concrete Volume Calculator for specific construction needs.
- Aquariums & Pools: Determining how many gallons or liters of water a tank holds.
- Science & Education: Solving geometry problems and understanding 3D space.
? Frequently Asked Questions
First calculate the volume in cubic meters, then multiply by 1,000. Or calculate in cubic centimeters and divide by 1,000. This calculator does it automatically for you.
Volume is the amount of space an object occupies (external dimensions). Capacity is the amount of substance (like liquid) a container can hold (internal dimensions). For thin-walled containers, they are roughly the same.
A pipe is a cylinder. Measure the inner radius and the length, then use the Cylinder formula: V = π × r² × h.
