# Volume vs. Capacity: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 24, 2023
Volume refers to the amount of space an object occupies, while capacity indicates the maximum amount something can contain or produce.

## Key Differences

Volume is a measure of the space taken up by an object, whether solid, liquid, or gas. Capacity, on the other hand, refers to the potential or maximum amount that a container or system can hold.
In everyday language, one might consider volume when thinking about the size of a book or the sound level of music. In contrast, capacity would be more relevant when considering how much water a bottle can hold.
Scientifically, volume is used to measure the three-dimensional space an entity occupies. Capacity is concerned with the maximum potential or limit of something, often in terms of containment.
Volume can be constant for solid objects, but for containers, it represents their total possible filled space. Capacity indicates the upper limit of how much a container can hold without overflowing.
For example, the volume of a cube is calculated by multiplying its length, width, and height. The capacity of a water tank, however, would tell us the maximum amount of water it can store.
