1 ft³ = 0.028317 m³ (exact NIST conversion factor)
- 1
Input volume (ft³)
100 - 2
Conversion factor (1 ft = 0.3048 m, cubed)
0.0283168471 foot = 0.3048 m exactly; 0.3048³ = 0.028316846592 m³/ft³. - 3
Cubic meters = ft³ × factor
100 × 0.028317 = 2.831685
How does this calculator work?
Multiply cubic feet by 0.028317 to get cubic meters (1 ft³ = 0.028317 m³ exactly). The reverse is × 35.315. For example, 100 ft³ = 2.832 m³. Enter any cubic-foot value above to instantly see cubic meters, liters, gallons, cubic inches and more.
Formula
How this is calculated
One foot equals exactly 0.3048 metres (since 1959 by international agreement). Cubing both sides gives 1 ft³ = 0.3048³ = 0.028316846592 m³ exactly. This calculator multiplies any cubic-foot value by that factor to produce cubic metres.
The reverse direction — cubic metres to cubic feet — divides by the same factor (or equivalently multiplies by 35.3147). Both directions use the same single exact constant; no rounding is introduced at the conversion step itself.
The additional unit conversions all derive from established factors: 1 ft³ = 1728 in³ (12³ exactly); 1 ft³ = 1/27 yd³ (3³ exactly); 1 ft³ = 28.3168 L (since 1 m³ = 1000 L); 1 ft³ ≈ 7.48052 US liquid gallons (since 1 US gal = 231 in³ exactly, and 1728/231 ≈ 7.48052). All intermediate rounding is held to more digits than displayed, so the table is reliable to the number of decimal places shown.
Frequently asked questions
One cubic foot equals exactly 0.028316846592 cubic meters. To convert, multiply your cubic-foot value by 0.028317. For example, 100 ft³ = 2.8317 m³.
Multiply cubic meters by 35.3147. For example, 1 m³ = 35.3147 ft³. Alternatively, divide by 0.028317.
One cubic foot equals approximately 28.3168 liters. Since 1 m³ = 1000 L and 1 ft³ = 0.028317 m³, we get 0.028317 × 1000 = 28.317 L.
