What is a Cubic Feet Calculator?
A Cubic Feet Calculator is a free tool that helps you calculate the volume of a space in cubic feet. It determines the cubic footage based on the length, width, and height of the space.
This calculator is useful for:
- Shipping and Moving - Estimating the volume of boxes and containers.
- Construction and DIY - Calculating material needs for projects like concrete slabs or garden beds.
- Storage - Determining the capacity of storage units or refrigerators.
To understand how volume is measured in different units, check out our Volume Converter to see how cubic feet compares to liters, gallons, and more.
For land area calculations, explore our Acreage Calculator to convert between square feet, acres, and other units.
To convert between different units of length, use our Length Converter to easily switch between feet, meters, inches, and more.
How This Calculator Works
The calculation uses the formula:
Where:
- Length = The longest side of the object.
- Width = The shorter side of the object.
- Height = The vertical dimension of the object.
The calculator first converts all input measurements into feet and then multiplies them to get the result in cubic feet.
Key Concepts Explained
Volume
Volume is the amount of three-dimensional space occupied by an object, often expressed in cubic units.
Cubic Foot (ft³)
A cubic foot is an imperial and US customary unit of volume, equivalent to the volume of a cube with 1-foot-long sides.

Frequently Asked Questions (FAQ)
Q: What is a cubic foot?
A: A cubic foot is a unit of volume that measures a cube with sides that are one foot long. It is commonly used in the United States for measuring the volume of spaces, such as rooms, shipping containers, and refrigerators.
Q: How do I calculate cubic feet?
A: To calculate cubic feet, you multiply the length, width, and height of an object or space. Make sure all measurements are in feet before you multiply. If your measurements are in other units, like inches or yards, you must convert them to feet first.
Q: Why is calculating cubic feet important?
A: Calculating cubic feet is important for a variety of applications, such as determining the capacity of a storage container, estimating the amount of material needed for a construction project, or figuring out the shipping cost for a package.
Q: Can I use this calculator for irregularly shaped objects?
A: This calculator is designed for rectangular or cube-shaped spaces. For irregularly shaped objects, you may need to break them down into smaller, regular shapes and calculate the volume of each part separately, then add them together.
