What is the standard unit of volume in the metric system?

The standard unit of volume in the metric system is the liter. This unit is widely used in various scientific and everyday contexts for measuring liquids and other substances. The liter is defined as the volume of a cube that measures 10 centimeters on each side, which is equivalent to 1,000 cubic centimeters.

While other units such as cubic meters, milliliters, and deciliters also represent volume, the liter is the most common unit used for general purposes in the metric system. A cubic meter is a larger unit that is typically used for measuring larger volumes, while a milliliter is a smaller unit where 1 liter equals 1,000 milliliters. Deciliters, which are one-tenth of a liter, are also used but are less common in everyday measurements compared to the liter. Thus, the liter stands out as the standard metric unit for everyday volume measurement.
