Cubic Meter Calculator
Calculate cubic meters from metric room, box, area plus depth, or cylinder measurements.
This page keeps cubic meters as the main result and includes quick conversions to litres, cubic feet, cubic yards, and cubic centimetres.
Results
This is a quick cubic meter calculator for simple volumes. Use trade-specific calculators for concrete, gravel, water volume, or material cost.
How to use this calculator
- 01Choose box / room, area + depth, or cylinder.
- 02Enter the dimensions in meters. Decimals are fine, such as 2.5 m.
- 03Read the m³ result as the primary volume.
- 04Use the litres, cubic feet, cubic yards, and cubic centimetres rows when you need a quick conversion.
If your measurements are in feet and inches, use the Cubic Feet Calculator. It keeps cubic feet primary and includes a cubic meter conversion.
Understanding the math
Cubic meters measure volume. Enter dimensions in meters, then use the volume formula for the selected shape.
box_volume = length x width x height area_depth_volume = square_meters x depth cylinder_volume = pi x (diameter / 2)^2 x height litres = cubic_meters x 1000 cubic_feet = cubic_meters x 35.3146667 cubic_yards = cubic_meters x 1.30795062 cubic_centimetres = cubic_meters x 1000000

Frequently asked questions
How to calculate cubic meters?
For a box or room, multiply length x width x height in meters. This calculator also handles square meters x depth and cylinders.
How to calculate cubic meters from square meters?
Multiply square meters by depth in meters. For example, 12 m² at 0.15 m deep is 1.8 cubic meters.
How to calculate cubic meters of a cylinder?
Use pi x radius squared x height, with radius and height in meters. If you measured diameter, divide it by 2 first.
What size is 1 cubic metre?
One cubic metre is the volume of a cube that is 1 m long, 1 m wide, and 1 m high. It is also 1,000 litres.
Can I use this calculator with feet or inches?
This page is built for meters and cubic meters. For feet-and-inches inputs, use the Cubic Feet Calculator, which also shows a cubic meter conversion.
