Volume is the measure of how much space an object takes or the amount of space taken up by a three-dimensional object. Volume of liquid refers to the capacity of liquids in the containers or refers to a quantity of liquid or the amount of space taken up by a liquid that absolutely spreads to fill its storage place. The volume of a container is generally understood to be the capacity of the container, i.e. the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.
Capacity can be measured by using non standard units (more or less) and in standard units in the metric system. The Metric System Units for measuring volume are millilitres and litres. Millilitres are used to measure a small liquid volume, such as a dosage of cough medicine and heavy cream. The volume of a bigger amount, like a bottle of mineral water, an aquarium or swimming pool can be measured using litres.
There are numerous tools used for measuring volume such as:
| 1) Measuring spoons |  |
| 2) Measuring cups |  |
| 3) Burette |  |
| 4) Graduated Cylinders |  |
| 5) Beakers |  |
