The cubic foot is a volume measure from the imperial and United States Customary systems. You can determine the cubic feet of an area by typing in the length, width, and height of your object in feet into our cubic feet calculator. Or, find the numbers yourself with our cubic feet formula.
To determine cubic feet, measure your object’s width, length, and height and type each dimension into our calculator.
If you prefer to do calculations yourself, determine the cubic feet of an area with the following formula:
Cubic feet = length x width x height in feet
Calculating Cubic Feet of a Cord of Wood
The standard dimensions for a cord of wood are 4 feet in width, 4 feet in depth, and 8 feet in height, resulting in a stacked volume of 128 cubic feet (cu ft).
Cubic Feet = 8 feet x 4 feet x 4 feet = 128 cubic feet
How to Convert Cubic Feet to Other Measurements
Here’s how to convert cubic feet to other standard volume measurements.
There are 1,728 cubic inches in one cubic foot. To go from cubic inches to cubic feet, divide by 1728.
Cubic feet = cubic inches ÷ 1,728
There are 27 cubic feet in one cubic yard. So to go from cubic yards to cubic feet, multiply your yards’ value by 27.
Cubic feet = cubic yards x 27
There are 7.48052 gallons in one cubic foot. To go from gallons to cubic feet, multiply your gallons number by 7.48052.
Cubic feet = gallons x 7.48052
How to Calculate Cubic Feet of a Refrigerator
To measure the cubic feet of a refrigerator, start by opening the doors, removing shelves and drawers, and then measuring the interior’s width, height, and depth in feet. Then multiply those numbers together.
Cubic feet of refrigerator = interior depth x width x height in feet
If you don’t know how to measure feet, take your measurements in inches and multiply them by each other. Then, divide your cubic inches total by 1,728 to determine the cubic feet.
For example, if your refrigerator measures 18 x 25 x 48 inches, start by calculating the number of cubic inches:
- 18 x 25 x 48 = 21,600 cubic inches
- 21,600 ÷ 1728 = 12.5 cubic feet
Most refrigerators range from 10 to 25 cubic feet.
How to Calculate Cubic Feet of a Microwave
To determine the number of cubic feet in a microwave, open the door and measure the depth, width, and height in feet. Then multiply those numbers by each other.
You can also measure in inches and convert cubic inches to cubic feet. So, if your microwave measures 12 x 21 x 10 inches, multiply those numbers together and then divide by 1,728 to calculate cubic feet.
- 12 x 21 x 20 = 5,040 cubic inches
- 5,040 ÷ 1,728 = 2.196 cubic feet
Frequently Asked Questions (FAQ)FAQ
How many square feet are one cubic foot?
Square feet and cubic feet don’t measure the same thing. Square feet measure area, like a piece of land, while cubic feet measure volume. A square foot is a measure of length x width. Cubic feet is length x width x height. For example, one cubic foot of mulch will cover about four square feet of the ground when three inches thick. If you increase or decrease the thickness, the amount of area the mulch covers will change.
How many cubic feet is a 10 x 10 room?
To find the cubic feet of a room, you must know the length, width, and height of the room. Assuming the room has standard 8-foot ceilings, the cubic feet of a 10 x 10 x 8-foot room is 800 cu. ft.
How many cubic feet are in a 12 x 12 x 8 room?
There are 1,152 cubic feet in a 12 x 12 x 8-foot room.
How big is a seven cubic foot freezer?
A 7 cubic foot freezer refers to the space inside the freezer and can hold about 175 lbs worth of food. However, the amount you can fit will depend on the orientation of the freezer.
