* Liter (L): This is the standard unit in the metric system.
* Milliliter (mL): This is a smaller unit within the metric system, equal to one-thousandth of a liter. It's commonly used for measuring smaller volumes.
* Cubic meter (m³): This is the standard unit of volume in the metric system. While not as common for liquids and gases, it's important for larger volumes.
* Cubic centimeter (cm³): This unit is equal to one milliliter.
Other units you might encounter:
* Cubic decimeter (dm³): This unit is equal to one liter.
* Cubic inch (in³): This is a unit in the imperial system.
* Cubic foot (ft³): This is another unit in the imperial system.
* Gallon (gal): This is a unit of volume used in the US.
The specific unit chosen depends on the size of the volume being measured. For example, a chemist might measure the volume of a solution in milliliters, while an engineer might measure the volume of a gas tank in cubic meters.
