Cubic Feet Calculator
Free online cubic feet calculator to compute volume from length, width and height measurements. Instantly convert cubic feet to cubic yards for shipping, construction and storage.
About This Calculator
The Cubic Feet Calculator helps you quickly compute the volume of any rectangular space or object in cubic feet. Simply enter the length, width, and height in feet, and the calculator instantly returns the total volume in cubic feet and cubic yards. This tool is essential for shipping and logistics, construction material estimation, home improvement projects, and storage planning.
How It Works
The calculator uses the standard volume formula: Volume (ft³) = Length (ft) × Width (ft) × Height (ft). Once the cubic feet volume is calculated, it automatically converts the result to cubic yards by dividing by 27, since one cubic yard equals 27 cubic feet. Results are rounded to two decimal places for practical use. For example, a box measuring 10 ft × 10 ft × 5 ft has a volume of 500 cubic feet, which converts to approximately 18.52 cubic yards.
If your measurements are in inches, simply divide each dimension by 12 to convert to feet before multiplying. For centimeter measurements, divide by 30.48. The calculator handles these conversions behind the scenes to give you accurate results in your preferred unit.
Common Applications
Cubic feet measurements are widely used in the US and UK for measuring refrigerator and oven capacity, shipping container volumes, aquarium sizes, and construction materials like concrete, soil, and gravel. The cubic yard conversion is especially useful for landscaping projects where materials are sold by the cubic yard. In the US, freight shipping rates are often based on cubic feet, while in the UK, both cubic feet and cubic meters are used depending on the industry. For international shipping, knowing the cubic feet volume helps determine freight class and shipping costs accurately.
Frequently Asked Questions
How do I calculate cubic feet?
To calculate cubic feet, multiply the length, width, and height of the space in feet: Volume (ft³) = Length × Width × Height. For example, a box that is 2 ft long, 2 ft wide, and 2 ft high has a volume of 8 cubic feet.
How many cubic feet are in a cubic yard?
There are 27 cubic feet in 1 cubic yard. This is because a yard is 3 feet long, so a cubic yard measures 3 ft × 3 ft × 3 ft = 27 ft³.
How do I calculate cubic feet from inches?
To calculate cubic feet from inches, first convert each dimension from inches to feet by dividing by 12. Then multiply the three dimensions together. Alternatively, multiply all three dimensions in inches and divide the result by 1,728.
How do I calculate cubic feet from centimeters?
To calculate cubic feet from centimeters, divide each dimension in centimeters by 30.48 to convert to feet, then multiply them together. Alternatively, multiply the three dimensions in centimeters and divide by 28,316.847.
What are cubic feet used for?
Cubic feet are commonly used to measure volume for shipping containers, refrigerators, freezers, ovens, aquariums, storage spaces, soil and gravel for landscaping, concrete for construction, and cargo capacity in trucks and aircraft.
Is this cubic feet calculator free?
Yes, this cubic feet calculator is completely free to use with no limits or registration required. You can calculate as many volumes as you need.
