Customary Measurements

When we convert from a large measurement to a small unit, we multiply.

When we convert from a small measurement to a large unit, we divide.

​100 pennies = $1 dollar

There are 100 pennies in one dollar. The dollar is a larger unit than the penny. You need many pennies to equal one dollar. The same is true when working with units of length, weight and capacity. You need more of a smaller unit to equal a larger unit.
