Cubic Feet to Cubic Meters Converter (ft³ to m³)
1 ft³ = 0.028316846592 m³ exactly. Convert cubic feet to cubic meters for moving, firewood, storage and shipping, with ft³ and m³ charts.
Cubic Meter (m³) = Cubic Foot (ft³) × 0.028316846592
Cubic Foot (ft³): A cubic foot is a cube 1 foot on each side, equal to 1,728 cubic inches or exactly 28.316846592 liters. It is used in the US for room and appliance capacity and gas volumes.
Cubic Meter (m³): The cubic meter is the SI unit of volume: a cube 1 m on each side, equal to 1,000 liters. It is used for water and gas metering, concrete, shipping and earthworks.
| Cubic Foot (ft³) | Cubic Meter (m³) |
|---|---|
| 1 | 0.028316846592 |
| 5 | 0.14158423296 |
| 10 | 0.28316846592 |

Cubic feet measure the space in American refrigerators, moving trucks, storage units and firewood stacks, and the gas on a US utility bill, while freight forwarders, international movers and most product specifications outside the US quote cubic meters. One foot is exactly 0.3048 m, so a cubic foot is 0.3048 cubed, which comes to exactly 0.028316846592 m³.
To get cubic feet in the first place, multiply length, width and height in feet, or multiply the measurements in inches and divide by 1,728. The table works through real shapes, from a carry-on bag to a full cord of firewood, and the reverse chart lists cubic-meter figures of the size found in moving and storage quotes.

Formula
Cubic Meter (m³) = Cubic Foot (ft³) × 0.028316846592
Cubic Foot (ft³) = Cubic Meter (m³) × 35.3146667215
Both factors come from exact definitions: 1 cubic meter = 35.3146667215 cubic feet and 1 cubic foot = 0.028316846592 cubic meters (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
128 ft³ × 0.028316846592 ≈ 3.62456 m³
30 m³ × 35.3146667215 ≈ 1059.44 ft³

Quick mental estimate
Divide the cubic feet by 35: 700 ft³ → 20 m³. The exact answer is 19.82 m³, so the shortcut comes out about 0.9% high.

The two units
Cubic Foot (ft³): A cubic foot is a cube 1 foot on each side, equal to 1,728 cubic inches or exactly 28.316846592 liters. It is used in the US for room and appliance capacity and gas volumes.
Cubic Meter (m³): The cubic meter is the SI unit of volume: a cube 1 m on each side, equal to 1,000 liters. It is used for water and gas metering, concrete, shipping and earthworks.
Frequently asked questions
Why is a cubic foot not 0.3048 cubic meters?
Because volume has three dimensions, the length factor has to be cubed: 0.3048 × 0.3048 × 0.3048 gives 0.028316846592. Using 0.3048 directly would overstate the volume more than tenfold.
How big is a cord of firewood in cubic meters?
A cord is a stack 4 ft high, 4 ft wide and 8 ft long, 128 ft³ in all, or about 3.62 m³. That space includes the air between the logs, and a loosely thrown pile takes up more room for the same amount of wood.
How do I find the volume of a box in cubic feet?
Measure it in inches, multiply length × width × height, and divide by 1,728, the number of cubic inches in a cubic foot. A 24 × 18 × 18 in box holds 7,776 in³, which comes to 4.5 ft³ or about 0.127 m³.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
