What children learn in Level 52

America's everyday units are called customary units. They don't follow powers of 10, so a chart is your friend.
The rule hasn't changed. Bigger to smaller means multiply. 4 feet is 4 times 12 inches.
Smaller to bigger means divide. 15 feet is 15 divided by 3 yards.
A mile is 5,280 feet, which is about the length of 15 football fields.
