Cubic Feet Calculator
Calculate cubic feet quickly from length, width, and height. You can also convert cubic inches, cubic yards, cubic meters, liters, and other volume measurements to cubic feet.
Cubic Feet = Length × Width × Height
When your measurements are in inches: Cubic Feet = Length × Width × Height ÷ 1,728
What Is a Cubic Feet Calculator?
A cubic feet calculator is a simple online tool used to calculate the volume of a three-dimensional space in cubic feet. It can help you calculate cubic feet using the length, width, and height of an object, room, container, storage area, or construction space.
Instead of doing the calculation manually, enter your measurements into the calculator above and get the cubic feet result instantly. This calculator is useful for moving, shipping, storage, construction, landscaping, home improvement, and DIY projects.
How to Calculate Cubic Feet
To calculate cubic feet, multiply the length by the width and then multiply the result by the height. All three measurements should be expressed in feet.
Length = 10 feet
Width = 5 feet
Height = 4 feet
Cubic Feet = 10 × 5 × 4
Cubic Feet = 200 ft³
How to Calculate Cubic Feet From Inches
If your measurements are in inches, multiply the length, width, and height together and divide the result by 1,728. The number 1,728 comes from 12 × 12 × 12 because one foot contains 12 inches.
Length = 24 inches
Width = 12 inches
Height = 18 inches
24 × 12 × 18 = 5,184 cubic inches
5,184 ÷ 1,728 = 3 cubic feet
How Do You Calculate Cubic Feet?
The basic formula is: Length × Width × Height when all measurements are in feet. If the measurements use another unit, convert them to feet first or use the conversion calculator above.
Common Cubic Feet Conversions
- 1 cubic yard = 27 cubic feet
- 1 cubic foot = 1,728 cubic inches
- 1 cubic meter ≈ 35.3147 cubic feet
- 1 cubic foot ≈ 28.3168 liters
- 1 US gallon ≈ 0.133681 cubic feet
What Can You Use Cubic Feet For?
Knowing the cubic feet of an object or space can be useful for estimating storage capacity, shipping volume, moving boxes, room volume, concrete projects, landscaping materials, soil, gravel, sand, and other construction materials.
For example, if you are ordering material for a construction or landscaping project, calculating the volume first can help you estimate how much material you may need.
How Accurate Is This Calculator?
The calculator performs the mathematical volume calculation based on the measurements you enter. The result is as accurate as the measurements supplied. When estimating physical materials, it is often useful to allow additional material for waste, irregular shapes, or measurement differences.
Frequently Asked Questions About Cubic Feet
1. How do I calculate cubic feet?
Multiply the length, width, and height together when all three measurements are in feet. The formula is Length × Width × Height.
