What This Calculator Does
This tool converts a volume measured in cubic feet (ft³) into cubic meters (m³). Cubic feet is a common imperial unit used in the US and UK for shipping, refrigeration, gas metering and construction, while cubic meters is the standard metric (SI) unit used worldwide. The conversion is exact and based on the relationship that one cubic meter equals 35.3147 cubic feet.
How to Use It
Type the volume in cubic feet into the input box and the calculator returns the equivalent volume in cubic meters. You can enter whole numbers or decimals — for example a 200 ft³ refrigerator or a 1,500 ft³ shipment.
The Formula Explained
The conversion uses a single division:
$$\text{Cubic Meters} = \frac{\text{Volume (ft}^3\text{)}}{35.3147}$$
Because 1 meter equals 3.28084 feet, one cubic meter is \(3.28084^3 \approx 35.3147\) cubic feet. To go the other way (m³ to ft³) you multiply by 35.3147 instead.
Worked Example
Suppose you have a 100 ft³ container. Divide by the factor: $$100 \div 35.3147 = 2.8317 \text{ m}^3$$ So 100 cubic feet is about 2.83 cubic meters.
FAQ
