We use tables of conversion factors and a calculator to convert customary units to other customary units, such as ounces to pounds and to tons, miles to feet and to inches, gallons to ounces, and so on (length, weight, capacity).
I solve three word problems that involve conversions between customary measuring units. For example, one of them is, how many 6-ounce servings do you get from 9 gallons of coffee?
Use ratios to convert measurement units
