In the metric system, the most commonly used unit for measuring volume is the liter (L). A liter is defined as the volume of a cube with sides of 10 centimeters (cm) in length, which is equivalent to 1,000 cubic centimeters (cm³).
Volume can also be measured in milliliters (mL), where 1 liter is equal to 1,000 milliliters. This makes milliliters a more convenient unit for measuring smaller volumes, such as liquids. For example, many beverages are often sold in liters or milliliters.
In scientific contexts, especially in chemistry, volume might also be expressed in cubic meters (m³) or cubic centimeters (cm³), where 1 m³ equals 1,000,000 cm³. Understanding these various units is essential in the metric system as it allows for easy conversions and calculations in everyday situations and scientific measurements.
