Using Ratio Reasoning to Convert Measurement Units

How many yards? How many feet? How many inches?

To do so, you would use a conversion rate. In problems which involve measurements (length, weight, volume, time, etc.), it is often necessary to convert from one measurement unit to another. To do so, you would use a conversion rate.

List some conversion rates that you know. Write them in ratio format. For example: 60 min 1 hour

Did you remember these? 60 sec 60 min 1 day 7 days 1 min 1 hr 24 hrs 1 week 1 mile 100 cm 1 gallon 5280 ft 1 meter 4 quarts

Conversion Table Provides equivalents for changing from one unit of measure to another Typically includes measurements of length (standard and metric), volume, time, and weight.

Tina has 5 quarts of milk. How many cups of milk does she have? Example #1: Tina has 5 quarts of milk. How many cups of milk does she have?

Example #2: How many minutes are in 2 days?

Example #3: A poster board is 108 inches wide. If it is cut in half, how many feet wide will each piece be?
