Instant, two-way conversion across common engineering units.
1 ft³ = 0.028316847 m³(Cubic foot → Cubic metre)
To convert cubic feet to cubic meters, multiply the value by 0.028316847. Volume conversions matter for concrete pours, excavation, tank capacity and airflow, where a rounding slip becomes a delivery error.
The cubic foot (ft³) is the standard imperial unit for bulk volume and airflow.
The cubic meter (m³) is the SI derived unit of volume and the standard measure for bulk construction materials.
1 ft³ equals 0.028316847 m³.
Multiply the value by 0.028316847. For example, 10 ft³ equals 0.28316847 m³.
1 m³ equals 35.314667 ft³. The converter above works in both directions, so you can type into either field.
The US gallon comes from the old English wine gallon of 231 cubic inches, while the imperial gallon was redefined in 1824. The imperial gallon is about 20 percent larger.
Cubic meters are the standard ordering unit for concrete and excavation in metric practice; cubic yards serve the same role in the US.
