What is a Cubic Foot?

Cubic footage is the volume of a space measured in feet. It’s the volume of a cube with width, length, and height equal to one foot.[1]

Measurements in cubic feet are primarily used in the US and parts of Canada.

Knowing the cubic footage of an object or space is often necessary for shipping, freight, and landscaping projects.

How to Calculate Cubic Feet

The first step to finding cubic feet is to measure the length, width, and height of a space or item.

Then, convert the dimensions to feet.

Finally, apply the volume formula to solve cubic feet:

volume = length × width × height

How to Calculate Cubic Footage using Dimensions in Feet

To calculate cubic feet using dimensions that are already in feet, use the formula above to solve by multiplying the three measurements together.

For example, let’s calculate cubic footage of a volume that is 2 feet long, 3 feet wide, and 1 foot high.

volume = 2′ × 3′ × 1′
volume = 6 cu ft

How to Calculate Cubic Footage using Dimensions in Inches

If your measurements are in inches, then convert them to feet by dividing the inch measurement by 12, or use our handy inches to feet conversion utility.

Next, follow the steps above to calculate using dimensions in feet.

For example, let’s calculate cubic footage of a volume that is 36 inches long, 48 inches wide, and 24 inches high.

Start by converting all dimensions to feet.

length = 36″ ÷ 12 = 3′
width = 48″ ÷ 12 = 4′
height = 24″ ÷ 12 = 2′

Then enter the dimensions into the volume formula and solve.

volume = 3′ × 4′ × 2′
volume = 24 cu ft

Alternative Method

An alternative approach is to enter the inch measurements into the volume formula above and solve to find the volume in cubic inches.

Then, convert the volume in cubic inches to cubic feet by dividing by 1,728.[2]

cu ft = cu in ÷ 1,728

You can also convert using our handy cubic inches to cubic feet conversion utility.

For example, let’s calculate cubic feet using this alternative method.

Start by finding cubic inches.

volume = 36″ × 48″ × 24″
volume = 41,472 cu in

Then divide by 1,729 to find cubic feet.

volume = 41,472 cu in ÷ 1,728
volume = 24 cu ft

How to Calculate Cubic Feet using Dimensions in Other Units

If your measurements are in yards, centimeters, meters, or another unit of length, then the process to find cubic footage is similar to that when the dimensions are in inches.

Start by converting your measurements to feet. We offer several length unit conversion utilities to simplify this conversion, and the calculator above allows entering several units.

Finally, enter the converted measurements into the volume formula and solve.

How to Find Cubic Footage of a Cylinder

To find the volume of a cylinder, use this formula:

cu ft = π × radius2 × height

Enter the radius and height in feet to get the volume in cubic feet. We also have a cylinder volume calculator that makes it easy to solve.

How to find Cubic Feet using Area and Height

Given the area of a space it’s possible to find cubic footage if the height is also known. The formula for volume using area and height is:

volume = area × height

The volume is equal to the area times the height.

How to find Cubic Feet using Square Feet

Square footage is a measure of area. Since volume is equal to area times height, simply multiply square feet times the height in feet to find the cubic footage.

You can also use a calculator like our square footage to cubic footage calculator to simplify the conversion.

For example, let’s calculate cubic feet of a 5 square foot area that is 3 feet high.

Start by finding cubic inches.

volume = 5 sq ft × 3 ft
volume = 15 cu ft

How to Convert Other Volume Units to Cubic Feet

If you have a volume measurement in cubic inches, cubic yards, cubic centimeters, or cubic meters, you can convert to cubic feet using a simple formula.

This table shows the formula to convert several forms of volume to cubic footage.
Volume UnitFormula
cubic inchescu ft = cu in ÷ 1,728
cubic yardscu ft = cu yds × 27
cubic centimeterscu ft = cu cm ÷ 28,316.8
cubic meterscu ft = cu m × 35.3

For example, let’s convert 3 cubic yards to cubic feet.

Start by locating the formula in the table above.

volume = cu yds × 27

Then enter the measurement to the formula and solve.

volume = 3 × 27
volume = 81 cu ft

You can also use a volume conversion calculator to easily convert.

What are the Dimensions of One Cubic Foot?

As mentioned above, a cube with the volume of one cubic foot has sides that are one-foot in each dimension. See the table below for the dimensions in other units of measure.

Dimensions of a cube with a volume of one cubic foot.
inches12″ × 12″ × 12″
yards0.334 yd × 0.334 yd × 0.334 yd
centimeters30.48 cm × 30.48 cm × 30.48 cm
meters0.3048 m × 0.3048 m × 0.3048 m
