Cubic Feet Calculator
A cubic feet calculator is a geometric volume tool that calculates the three-dimensional space of an object or area in cubic feet. It operates by multiplying length, width, and height dimensions, and it supports multiple input units like inches, yards, centimeters, and meters by converting them to feet prior to calculation. This utility is widely used in shipping, construction, and landscaping. Professionals and DIYers use it to determine the exact volume needed for materials like soil, concrete, gravel, shipping boxes, and storage spaces.
Enter length, width, and height in any common unit. We compute the volume in cubic feet, cubic yards, and cubic meters. Useful for storage, shipping, refrigeration, and HVAC sizing.
Quick Answer
Calculate the volume of a space in cubic feet. Enter the length, width, and height in your preferred unit to find the capacity.
Measurement unit
Enter all three dimensions in the same unit. Switch units at the top if your measurements are in inches, yards, centimeters, or meters.
Cubic feet
800
10 × 10 × 8 ft
Examples
Refrigerator interior, 28 × 28 × 60 in
≈ 27.2 cu ft
Storage unit, 10 × 10 × 8 ft
= 800 cu ft
Moving box, 18 × 18 × 24 in
≈ 4.5 cu ft
Room, 4 × 5 × 2.4 m
≈ 1,695 cu ft
How it works
All three measurements are converted to feet and multiplied together. The result in cubic feet is then converted to cubic yards and cubic meters using fixed factors.
Volume · L × W × H = cubic feet
1 cu yd = 27 cu ft · 1 cu m ≈ 35.314 cu ft · 1 in = 1/12 ft · 1 yd = 3 ft · 1 m ≈ 3.281 ft
Cubic feet, cu ft and cft
The same unit goes by several written forms. Cubic feet is often shortened to cu ft, to ft3, or simply to cft, and shipping and storage quotes in particular tend to use cft. They all mean the same measurement of volume, and it is what this calculator returns from a length, a width and a height.
