About the cubic feet calculator
Cubic feet measures volume — how much three-dimensional space something takes up — and for any box-shaped space, it's found with one formula: length multiplied by width multiplied by height, all in feet. That covers everything from a moving box to a garden bed to a room's total air volume.
This calculator accepts measurements in feet, inches, or meters, since real-world dimensions come in all three depending on what you're measuring — furniture and shipping boxes are often labeled in inches, rooms in feet, and international products in meters or centimeters. Enter your dimensions in whichever unit you have, and it converts everything to feet before multiplying.
Alongside cubic feet, the calculator also shows cubic yards (cubic feet divided by 27, the standard unit for ordering mulch, soil, or concrete), cubic meters, and liters — useful for cooler and container capacity, shipping volume, or comparing against metric spec sheets.
Common uses include estimating moving truck or storage unit space, figuring out how much soil, mulch, or gravel to order for a garden bed, checking appliance or cooler capacity, and calculating shipping volume for freight, which is often priced by cubic feet or cubic meters rather than weight alone.
Cubic feet calculator questions
How to calculate and convert volume.
How do I calculate cubic feet?
Multiply length by width by height, all measured in feet. For example, a box that's 2 ft x 2 ft x 3 ft has a volume of 2 x 2 x 3 = 12 cubic feet.
How do I convert inches to cubic feet?
Measure length, width, and height in inches, then either convert each to feet first (divide by 12) or use this calculator's inches option, which handles the conversion automatically.
How many cubic feet are in a cubic yard?
27 cubic feet make one cubic yard (3 ft x 3 ft x 3 ft = 27 cubic feet), which is the standard unit for ordering bulk materials like mulch, soil, and concrete.
How do I calculate cubic feet for a room?
Multiply the room's floor area (length x width) by its ceiling height, all in feet. A 10 ft x 12 ft room with an 8 ft ceiling is 10 x 12 x 8 = 960 cubic feet.
How many cubic feet is a standard moving box?
A typical medium moving box (18" x 18" x 16") is about 3 cubic feet, while a large box (18" x 18" x 24") is about 4.5 cubic feet.
What's the difference between cubic feet and square feet?
Square feet measures a flat area (length x width), while cubic feet measures volume (length x width x height). A room's floor might be 120 square feet, but its total air volume in cubic feet also depends on ceiling height.
