What Is a Cubic Meters to Cubic Feet Converter?
This calculator converts a volume measured in cubic meters (m³), the SI metric unit of volume, into cubic feet (ft³), the imperial/US customary unit. It is useful for shipping and freight (where container and cargo volume is often quoted in both systems), HVAC airflow, construction material estimates, and gas or water volume calculations.
How to Use It
Enter the volume in cubic meters and the calculator instantly returns the equivalent in cubic feet. The conversion is exact and works for any positive number, from a fraction of a cubic meter to large industrial volumes.
The Formula Explained
One meter equals approximately 3.28084 feet, so one cubic meter equals 3.28084³ ≈ 35.3147 cubic feet. The conversion is therefore a simple multiplication:
$$\text{ft}^3 = \text{m}^3 \times 35.3147$$
To go the other way, divide cubic feet by 35.3147 (or multiply by 0.0283168).
Worked Example
Suppose you have a shipping crate with a volume of 2.5 m³. Multiply by the conversion factor: $$2.5 \times 35.3147 = 88.29 \text{ ft}^3$$ So 2.5 cubic meters is about 88.29 cubic feet.
FAQ
How many cubic feet are in one cubic meter? Exactly 35.3146667 cubic feet, commonly rounded to 35.3147.
How do I convert cubic feet back to cubic meters? Divide the cubic feet value by 35.3147, or multiply by 0.0283168.
Is this conversion exact? Yes — it is based on the exact definition of 1 foot = 0.3048 meters, giving an exact factor of 35.3146667 ft³ per m³.
