Volume in different units

The same box expressed in cubic metres, cubic yards, and cubic feet.

How it works

A cubic metre is the volume of a cube one metre on each side. Multiply length by width by height in metres; the calculator converts other units to metres first.

volume = length × width × height
1 m³ = 1000 L = 35.3147 ft³ = 1.30795 yd³

Worked example

A 2 m × 1.5 m × 1 m space is 2 × 1.5 × 1 = 3 m³, which is 3,000 litres.
