To convert cubic feet to cubic meters, apply m³ = ft³ × 0.0283168. For example, 25 ft³ = 0.707921 m³, and 1 ft³ is 0.0283168 m³.
A foot is exactly 0.3048 m, so a cubic foot is 0.3048³ — exactly 0.028316846592 m³ — and a cubic meter is about 35.3147 ft³. Cubing is the usual trap: a meter is 3.28 ft, but a cubic meter is 35.3 cubic feet, not 3.28.
Everything on this page is computed in your browser from the exact definitions above — the table is not a stored list of pre-rounded answers, and neither is the converter. For a unit not covered here, the full unit converter handles length, weight, volume, temperature and cooking measures.
How many cubic meters is 25 ft³?
25 ft³ = 0.707921 m³. m³ = ft³ × 0.0283168, so any amount converts the same way — the table on this page lists the values most often looked up.
What is the formula for converting cubic feet to cubic meters?
m³ = ft³ × 0.0283168. A foot is exactly 0.3048 m, so a cubic foot is 0.3048³ — exactly 0.028316846592 m³ — and a cubic meter is about 35.3147 ft³. Cubing is the usual trap: a meter is 3.28 ft, but a cubic meter is 35.3 cubic feet, not 3.28.
Is the cubic feet to cubic meters conversion exact?
The underlying relationship is an exact definition, not a measurement. The decimal factor shown (0.0283168 m³) is a rounding of it, so results here are given to six significant figures — enough for any practical use, and you can see the exact definition above.
How do I convert cubic meters back to cubic feet?
Use the reverse of the same relationship; the cubic meters to cubic feet page has its own table and converter.
