Cubic Feet to Cubic Meters
Cubic metres = cubic feet × 0.0283168. 27 ft³ (one cubic yard) = 0.7646 m³; 100 ft³ = 2.83 m³; an 80 lb concrete bag's 0.6 ft³ yield is 0.017 m³.
m³ = ft³ × 0.0283168 yd³ = ft³ ÷ 27
Worked example
100 ft³ × 0.0283168 = 2.832 m³ (3.70 yd³).

How to Convert Cubic Feet to Cubic Metres
- Work out the volume in cubic feet (length × width × height in feet).
- Multiply by 0.0283168.
- Round to suit the job: two decimals for concrete orders, three for small volumes.
Example: a 10 × 10 ft slab 4 in (0.333 ft) thick is 33.3 ft³ × 0.0283168 = 0.94 m³.

Frequently Asked Questions
How do I convert cubic feet to cubic metres?
Multiply by 0.0283168 (0.3048³). 50 ft³ × 0.0283 = 1.416 m³.
How many cubic feet in a cubic yard?
27 ft³ (3 × 3 × 3), which is 0.7646 m³.
How many litres is a cubic foot?
28.32 L.
How do I calculate cubic feet?
Multiply length × width × height in feet. A box 4 × 3 × 2 ft is 24 ft³. If you measured in inches, multiply and divide by 1,728 (12 × 12 × 12).
How big is 1.8 cubic feet?
About 51 litres or 0.051 m³: a cube about 1.2 ft (14.6 in) on each side.
What is CFT?
CFT means cubic feet (ft³). It is the usual unit for sand, aggregate and concrete in India and Pakistan. 1 CFT = 0.0283 m³, and 1 m³ = 35.31 CFT.
How many CFT is 1 brass?
1 brass = 100 CFT, which is 2.83 m³. Brass is used for sand and aggregate loads in parts of India.
How many CFT of sand are in a ton?
About 22 CFT per tonne of dry, loose sand at 1,600 kg/m³ (45.3 kg per CFT). Damp or compacted sand is heavier, so a tonne fills fewer CFT.
