Examples

Refrigerator interior, 28 × 28 × 60 in

≈ 27.2 cu ft

Storage unit, 10 × 10 × 8 ft

= 800 cu ft

Moving box, 18 × 18 × 24 in

≈ 4.5 cu ft

Room, 4 × 5 × 2.4 m

≈ 1,695 cu ft

How it works

All three measurements are converted to feet and multiplied together. The result in cubic feet is then converted to cubic yards and cubic meters using fixed factors.

Volume · L × W × H = cubic feet

1 cu yd = 27 cu ft · 1 cu m ≈ 35.314 cu ft · 1 in = 1/12 ft · 1 yd = 3 ft · 1 m ≈ 3.281 ft

Frequently asked questions

Multiply length by width by height with all three values in feet. If you measured in inches, divide each measurement by 12 first; if you measured in yards, multiply by 3. The calculator does this for you when you choose a unit.

27. A cubic yard is 3 feet on a side, and 3 × 3 × 3 = 27 cubic feet.

About 35.31. We compute this conversion for you whenever you enter values, regardless of the unit you use.
