Think and Write What do units of capacity measure?

Metric Units of Capacity The metric units of capacity are: Milliliter (mL) Liter (L) In the U.S.A. we use customary units of capacity, such as cups, pints, and gallons, to measure how much liquid an item holds. Most other countries use metric units of capacity.

Milliliters A milliliter (mL) is a very small amount of liquid. You can use an eyedropper to measure a milliliter. Milliliters are used to measure smaller capacities, like the amount of liquid given to a baby for medicine. You can also use it for measuring a small glass of milk. 1,000 mL= 1 Liter

Liters Liters (L) are used to measure larger amounts of liquid. Liters are used to measure the amount of water in a sink or bathtub as well as the amount of water in a pool. Some water bottles can hold 1 liter. What capacities would you measure using liters?

Practice! Choose the correct unit to measure the capacity of the item, liter (L) or milliliter (mL). Swimming pool Medicine cup Juice box Can of paint

Choose the correct measurement! 1. 5 mL or 5 L 2. 200 mL or 200 L 3. 6 L or 60 L
