Box Volume Calculator (cm to liters)
Find the volume of a rectangular box (cuboid) by multiplying length, width and height. Enter all three sides in centimeters and get the result in cm³ and liters.
Enter length, width and height to see the volume.
How it works
How box volume works
The volume of a rectangular box equals length × width × height. When every side is measured in centimeters, the result comes out in cubic centimeters (cm³).
To convert to liters, divide the cubic centimeters by 1000, since 1 liter equals 1000 cm³.
Where it is useful
Box volume is handy for shipping, packing and storage, where carriers often charge by volumetric weight rather than actual weight.
It also helps with everyday tasks like sizing containers, aquariums or moving cartons.
Frequently asked questions
›What is the formula for box volume?
Volume = length × width × height. With all sides in centimeters, the result is in cubic centimeters (cm³).
›How do I convert cm³ to liters?
Divide the volume in cm³ by 1000. For example, 2000 cm³ equals 2 liters.
›Do all sides need the same unit?
Yes. Enter length, width and height all in centimeters so the result is consistent.
›Can I use it for shipping estimates?
Yes. Many carriers use volume to calculate volumetric weight, so the cm³ and liter results are useful.
›What if a box is not a perfect rectangle?
This calculator assumes a rectangular box (cuboid). For irregular shapes, measure the smallest box that contains the item.
