noun

Capacity is how much something can hold or how much space it has inside. Just like a cup can hold a certain amount of water, a bucket can hold more water than a cup because it has a greater capacity. It's like the size of a container and how much it can fill up.

Example

1. The capacity of the water bottle is 500ml.
2. The stadium has a capacity of 50,000 people.
3. The truck's fuel tank has a capacity of 100 liters.
