To calculate cubic feet, multiply length × width × height. If your measurements are in feet, the result is cubic feet. If measurements are in inches, divide by 1,728 to convert to cubic feet.
Divide the cubic inches by 1,728. There are 1,728 cubic inches in one cubic foot (12 × 12 × 12 = 1,728).
Yes, measure your dimensions in inches, multiply them together to get cubic inches, then divide by 1,728 to get cubic feet. Our calculator handles this conversion automatically.
For irregular shapes, break them down into regular rectangular sections, calculate the cubic feet for each section separately, then add them together for the total volume.
Cubic feet calculations are useful for determining storage capacity of boxes, rooms, refrigerators, moving trucks, shipping containers, and calculating concrete or mulch needed for projects.
First convert meters to feet by multiplying by 3.28084, then calculate cubic feet normally. Alternatively, calculate cubic meters first, then multiply by 35.3147 to get cubic feet.
Convert yards to feet by multiplying by 3, then calculate cubic feet normally. Or calculate cubic yards first, then multiply by 27 to get cubic feet (since 1 cubic yard = 27 cubic feet).
