Converting cubic metres to cubic feet is one of the most important volume conversions in international engineering, construction, and trade. The cubic metre (m³) is the SI standard unit of volume used across most of the world, while the cubic foot (ft³) is the primary large-volume unit in the US customary and British imperial systems. Understanding how to move between these two units is essential for any professional working across metric and imperial measurement environments.
The exact conversion factor is 1 cubic metre = 35.314666721 cubic feet. This is derived directly from the definition of the metre — since 1 foot = 0.3048 metres exactly, one cubic foot = (0.3048)³ = 0.028316846592 m³, meaning 1 m³ = 1 ÷ 0.028316846592 = 35.3147 ft³. This conversion is critical in industries such as construction material estimation and concrete volume planning where metric designs must be implemented using imperial-measured materials.
Example: 5 m³ = 5 × 35.3147 = 176.573 ft³ | 100 ft³ = 100 ÷ 35.3147 = 2.832 m³
All values represent the exact equivalent of 1 cubic metre in different volume units.

The cubic metres to cubic feet conversion involves a straightforward multiplication using the precise conversion factor. Follow the steps below for an accurate manual conversion, or simply use our calculator above for instant results.
The cubic metre (m³) is the SI derived unit of volume. It equals the volume of a cube with sides exactly 1 metre in length. One cubic metre contains exactly 1,000 litres, 1,000,000 millilitres, or approximately 264.17 US gallons. It is the standard volume unit in metric countries for construction, science, and commerce.
The cubic foot (ft³) is a unit of volume in the US customary and British imperial systems. It equals the volume of a cube with each side measuring 1 foot (0.3048 metres). One cubic foot contains 1,728 cubic inches, approximately 28.317 litres, or 7.481 US gallons. It is widely used in real estate, HVAC, and US construction.
In global construction, project designs are often created using metric measurements (m³) but implemented with imperial materials (ft³) in North America. A standard room of 50 m³ equals approximately 1,765 ft³. Converting accurately between the two systems prevents costly over-ordering and structural errors on international building projects.
Heating, ventilation, and air conditioning (HVAC) engineers frequently work with both cubic metres and cubic feet when calculating airflow rates and duct sizing. Air volume in metric systems is expressed in m³/h, while US systems use ft³/min (CFM). Converting between these units is a daily task for HVAC professionals working across international standards.
International shipping and freight calculations commonly require converting cubic metres to cubic feet. A standard 20-foot shipping container has an internal volume of approximately 33.2 m³ or 1,172 ft³. Freight rates are often quoted per cubic metre (CBM) internationally but per cubic foot in the United States, making this conversion essential for logistics professionals.
Natural gas volumes are measured in cubic metres (m³) in most countries and in cubic feet (ft³) in the United States. Gas billing statements, pipeline capacities, and energy calculations all depend on this conversion. One cubic foot of natural gas equals approximately 0.02832 m³, and one cubic metre equals about 35.315 ft³ of gas volume.
For everyday use, rounding to 35.315 cubic feet per cubic metre is perfectly sufficient. However, for high-precision engineering, scientific research, or legal measurement applications, always use the full exact value of 35.314666721 cubic feet per cubic metre. In large-scale industrial projects, even a small rounding error multiplied across thousands of cubic metres can lead to significant material and cost discrepancies.
These are the most frequently searched cubic metres to cubic feet conversions used across construction, real estate, shipping, and engineering projects worldwide.
