Easily calculate the volume of cubes, rectangular boxes, and cylinders with our free online volume calculator. Enter your dimensions, click calculate, and get instant results in cubic units.
Calculate volume in Metric (m³ & liters) or Imperial (in³ & ft³) units.
Select shape – Choose between cube, rectangular box, or cylinder.
Enter dimensions – Provide the side length, length/width/height, or radius/height depending on the shape.
Select unit system – Pick Metric (m) or Imperial (inches).
Click Calculate – The tool will instantly display the volume in both:
Metric: cubic meters (m³) and liters (L)
Imperial: cubic inches (in³) and cubic feet (ft³)
Interpret results – Use the value for school, work, or everyday measurements.
Currently, the calculator supports cube, rectangular box, and cylinder. More shapes like sphere and cone will be added soon.
You can choose between Metric (m³ and liters) or Imperial (in³ and ft³).
No. Simply enter the dimensions in the selected unit system. The calculator will automatically display the results in the correct cubic units.
Yes, but remember the result will then be in cm³ instead of m³. If you want liters, enter the dimensions in meters.
Yes, our volume calculator is 100% free with no signup required.
This free online volume calculator is designed to quickly compute the capacity of common 3D shapes. Whether you are solving a geometry problem, checking storage space, or estimating container capacity, the calculator makes the process simple and accurate.
It supports both Metric and Imperial units, so you can switch between systems depending on your needs.
