Identify Equivalence of Metric Units of Capacity

When we think about capacity, we think about measuring liquids. In the Customary system of measurement, we measure liquids using cups, pints, ounces, gallons etc. In the Metric System of measurement, we measure capacity using two different measures, liters and milliliters.

Since there are only two metric units for measuring capacity, this text box shows them and their equivalent measures. Liters are larger than milliliters. Notice that prefix “milli” again.


When converting from large units to small units, you multiply.

When converting from small units to large units, you divide.


Example

4 liters = _____ milliliters

Liters are larger than milliliters, so we multiply by 1000.

4 liters = 4000 milliliters
