Defining and Converting U.S. System Units of Capacity

Units of capacity are generally used to measure liquids.

U.S. Units of Capacity

8 fluid ounces (fl oz) = 1 cup (c)

2 cups = 1 pint (pt)

2 pints = 1 quart (qt)

4 quarts = 1 gallon (gal)

Defining and Converting Metric System Units of Capacity

Metric Units of Capacity

1 kiloliter (kl) = 1000 liters (L)

1 hectoliter (hl) = 100 L

1 dekaliter (dal) = 10 L

1 liter (L) = 1L

1 deciliter (dl) = 1/10 or 0.1 L

1 centiliter (cl) = 1/100 L or 0.01 L

1 milliliter (ml) = 1/1000 or 0.001 L

Defining and Converting Metric System Units of Capacity

The milliliter and the liter are the two most commonly used metric units of capacity.
