Lesson 33

Multiple Unit Multipliers

Conversion of Units of Area

Review

• Use one unit multiplier to change 1 yard to feet.

• Use one unit multiplier to change 3 feet to inches.

Multiple Unit Multipliers

• We can use multiple unit multipliers

• String them together like before

• Example:

• 1 yard to inches:

Example 33.1

• Convert 360 inches to yards.

Example 33.2

• Use two unit multipliers to convert 1.4 kilometers to centimeters.

Example 33.3

• Use two unit multipliers to convert 24 miles to inches.

Conversion of Area

• use two unit multipliers

• the multipliers will usually be the same thing twice

Example 33.4

• Use two unit multipliers to convert 4 square feet to square inches.

Example 33.5

• Use two unit multipliers to convert 4 square meters to square centimeters.

Example 33.6

• Use two unit multipliers to convert 400 square inches to square feet.

Example 33.7

• Use two unit multipliers to convert:

• 6 miles to inches

• 20 square feet to square inches
