How to Find Cubic Meters

A cubic meter, or cubic metre in British English, is a measure of volume for a cube that has a length, width, and height of one meter. To calculate a volume in cubic meters, start by measuring your space.

When measuring, find the length, width, and height of the space in meters.

Next, multiply the three measurements together to find the volume in cubic meters.

It’s as easy as that! Use our volume calculator to find the volume of more complex shapes.

M3 = Length × Width × Height

Calculate Cubic Meters Using Centimeter and Millimeter Measurements

Often a space will have measurements that are not easy to find in meters, and the measurements are in centimeters or millimeters. That’s OK! Use the formulas below to find cubic meters using centimeter and millimeter measurements.

Finding M3 when all measurements are in CM can be done like this:
M3 = Length × Width × Height ÷ 1,000,000

Finding M3 when all measurements are in MM can be done like this:
M3 = Length × Width × Height ÷ 1,000,000,000
