## Metric Capacity

#### Aligned To Common Core Standard:

**Grade 4 Measurement** - 4.MD.A.1

Measures of Metric Capacity - The capacity or volume of an object is the amount of matter it can hold within it. The common units for measuring capacity or volume includes milliliters (ml) and liters (l). milliliters is a unit that we use for measuring very small volumes and liters is a unit which is used for measuring large quantities. Other units for measuring capacity include ounce (oz), cubic meters, cubic decimeters, and cubic centimeters. The principal measuring unit for capacity is liter but we use multiples and sub-multiples as per the quantity that we are dealing with. We cannot measure the volume of toothpaste bottle in kilometers which is used to specify the volume of an Olympic-size pool. For huge quantities we use kiloliter, hectoliter, and decaliter. For small quantities we use deciliter, centiliter, and milliliters. These worksheets help you convert metric values of capacity and understand their relative size.
