Cubic Feet Calculator
Enter dimensions to calculate cubic feet automatically
This is a free online tool to calculate the volume of a cuboid or a box, support metric and imperial units (inches, feet, yards, mm, cm or meter), simple CFT calculator with calculation formula and dynamic visual cube help us understand the answer more easily.
How to use this CFT calculator
- Fill the numbers into blanks of lenght, width and height
- Accept input decimals or fraction, eg. 1.4, 5.5, 1 7/8 or 3/8
- Choose the unit of measure you are using (in, ft, yd, mm, cm, m)
- Then you will know how many cubic feet(cf³) is it
How to calculate cubic feet ?
CFT is also known as cubic feet or ft3, a unit measurement of volume,
a cubic foot is the space occupied by a cube with 1 foot width, length and height.
Here is how to figure out the cubic feet,
if your unit of measurement is not feet,
convert the nuit to feet first, then,
multiply length, width and height values together,
this will give you the volume of the cube.
For example :
How to calculate the volume(cf3) of a carton that
dimension is 13 x 20 1⁄4 x 12 1⁄2 inches ?
Convert from measurements in inches to cubic feet,
when we measure the dimension of a carton with a ruler,
the unit is inches, and we need calculate the cubic feet.
- 13 in = 13 ÷ 12 = 1.083 ft
- 20 1⁄4 in = 20.25 ÷ 12 = 1.688 ft
- 12 1⁄2 in = 12.5 ÷ 12 = 1.042 ft
- 1.083 × 1.688 × 1.042 = 1.9048844 ft³
Unit conversion formula
- 1 inch = 1/12 feet = 0.0833333333 feet (convert inches to feet)
- 1 yard = 3 feet
- 1 mm = 0.1 cm = 0.0032808399 feet (convert mm to feet)
- 1 cm = 0.01 m = 0.032808399 feet (convert cm to feet)
- 1 meter = 3.2808399 feet (3 feet 3 3⁄8 inches) (convert meters to feet and inches)
Cubic feet formula for different units
If you don't want to convert the unit to feet first, that's ok, below are formulas for other units.
- length(feet) × width(feet) × height(feet) = cubic feet(cf³)
- length(inches) × width(inches) × height(inches) ÷ 1728 = cubic feet(cf³)
- length(yards) × width(yards) × height(yards) × 27 = cubic feet(cf³)
- length(cm) × width(cm) × height(cm) ÷ 28316.846592 = cubic feet(cf³)
- length(meters) × width(meters) × height(meters) × 35.31466688252347 = cubic feet(cf³)
