Convert Cubic Feet to Cubic Meters with Ease

Conversion factor

One cubic foot equals 0.0283168466 cubic meters — that's the cube of the foot-to-meter length factor (0.3048³). The calculator multiplies your entry by that constant and shows six decimal places, since cubic meter values from feet inputs are often small.

Worked example

A shipping crate measuring 4 ft × 3 ft × 2 ft has a volume of 24 cubic feet. Multiply by 0.0283168466: 24 × 0.0283168466 = 0.679604 cubic meters. That's the number a freight carrier would want on a cubic-meter-based rate sheet.

Why the factor has so many digits

The meter is defined independently of the foot, so the ratio between the two doesn't resolve to a clean decimal. 0.0283168466 is accurate to nine significant figures, which is more precision than almost any practical measurement (lumber dimensions, room volumes, shipping quotes) actually carries — the extra digits mostly matter for large volumes where small rounding errors compound.

Typical uses

This conversion comes up when comparing HVAC airflow rated in cubic feet per minute against metric equipment specs, when converting US lumber or aggregate volumes for an international bill of materials, or when a shipping quote needs cubic meters (CBM) but your measurements were taken in feet.
