You have already learned to find unit rates. (Lesson 6–2)
• Convert rates using dimensional analysis.
• dimensional analysis – the process of including units of measurement when computing
Convert Measurements Between Systems
A. Convert 3 liters to cups. Round to the nearest hundredth.
You have to convert liters to cups, but there is no conversion rate for liters to cups, so you need to use 1 liter ≈ 2.114 pints and 1 pint = 2 cups.
Convert from liters to pints and then pints to cups.
Divide out common units, leaving cups.
Simplify.
3 L ≈
≈ 12.68 cups
Answer: So, 3 liters is approximately 12.68 cups.
3 L 1
x 2.114 pt 1 L

B. Convert 7 kilometers to feet.
Use 1 km = 1000 m and 1 m ≈ 3.279 ft.
Divide out common units, leaving feet.
Simplify.
Answer: So, 7 kilometers is approximately 22,953 feet.
7 km ≈ 7 km 1
x 1000 m 1 km
x 3.279 ft1 m
≈ 22,953 feet
