🌍 Cubic Meter Calculator
Measure rectangular volumes in cubic meters and instantly view common conversions.
Enter the length, width, and height of your space in the unit you have. The calculator delivers cubic meters along with liters, cubic feet, and gallon equivalents for international collaboration.
Total Volume
15 m³
Dimensions converted to meters: 3.00 × 2.50 × 2.00 m
Liters (L)
15,000
Cubic Feet (ft³)

Tip: Multiply cubic meters by 1,000 to get liters. This is handy for tank sizing, irrigation planning, and beverage production.
How to Use This Calculator
Measure your space
Record the length, width, and height using a tape measure or site plans.
Pick the measurement unit
Match the unit dropdown to your measurement. Metric and imperial units are both supported.
Use the converted values
Apply the cubic meter and liter results to project specs, or switch to cubic feet and gallons for US-based teams.
Formula
Volume (m³) = Length × Width × Height
The calculator normalises every measurement to meters first, then multiplies the three dimensions. Additional outputs use exact conversion factors for liters, cubic feet, and gallons.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Cubic meters are the international standard for volume. Architects, facility planners, shipping coordinators, and environmental engineers depend on m³ to align designs, freight loads, and compliance reports across borders.
This calculator eliminates unit mismatches by accepting centimetres, millimetres, and imperial dimensions. The resulting conversions help you communicate with suppliers, contractors, or data systems that expect different units.
You can also translate the output into per-unit quantities (for example, water treatment flow, warehouse capacity per pallet, or air handling volume per hour) by combining this result with operational formulas.
Frequently Asked Questions
How accurate are the conversions?
They use internationally recognised constants (for example 1 m³ = 1,000 L = 35.3147 ft³). Results are rounded for readability but keep full precision in calculations.
Can I enter centimetres and get cubic meters?
Yes. Enter the dimensions in centimetres and the calculator converts them internally before computing the volume.
Does this work for shipping containers?
Absolutely. Measure the interior dimensions of the container, calculate cubic meters, and compare against freight or storage requirements.
What about cylindrical tanks?
This tool focuses on rectangular volumes. For cylindrical shapes, use the Gallon Calculator, which supports circular tanks.
