Length: Measurement Conversions

Miss Oberlander

Here’s a Little Rap to Help!

When you are converting on the fly,

Bigger to smaller, you multiply!

When you’re converting, don’t hide,

Smaller to bigger, just divide!

How to convert
• Given: 48 inches= __________ feet
• Step 1: Write what conversion you KNOW between inches and feet in the same order as the problem.

Know: ______ inches = 1 foot

Inches  feet

(small) TO (big)

• If you are going bigger to smaller, you will multiply! x
• If you are going smaller to bigger, you will divide! ÷

Step 3: Set up a math problem using what you know with what you were given.

Know: 12 inches = 1 foot

Given: 48 inches

48 ÷ 12 =

How to convert
• Given: 5 miles = __________ feet
• Step 1: Write what conversion you KNOW between inches and feet in the same order as the problem.

Know: 1 mile = ________ feet

miles feet

(big) TO (small)

• If you are going bigger to smaller, you will multiply! x
• If you are going smaller to bigger, you will divide! ÷

Step 3: Set up a math problem using what you know with what you were given.

Know: 1 mile = 5,280 feet

Given: 5 miles

5,280 x 5 =

How to convert
• Given: 52 yards= __________ feet
• Step 1: Write what conversion you KNOW between inches and feet in the same order as the problem.

Know: 1 yd = ________ feet

Yards  feet

(big) TO (small)

• If you are going bigger to smaller, you will multiply! x
• If you are going smaller to bigger, you will divide! ÷

Step 3: Set up a math problem using what you know with what you were given.

Know: 1 yard = 3 feet

Given: 52 yards

52 x 3 =

• The steps remain the same!
• Just remember the conversions we memorized:
• 1,000 millimeters = 1 meter
• 100 centimeters = 1 meter
• 10 decimeters = 1 meter
• 1,000 meters = 1 kilometer
• Multiplying and dividing with 10s is even easier!
• That’s why the rest of the world prefers to use METRIC rather than customary measurement.
How to convert
• Given: 200 centimeters = __________ meters
• Step 1: Write what conversion you KNOW between inches and feet in the same order as the problem.

Know: ___________centimeters = 1 meter

centimeters meters

(small) TO (big)

• If you are going bigger to smaller, you will multiply! x
• If you are going smaller to bigger, you will divide! ÷

Step 3: Set up a math problem using what you know with what you were given.

Know: 1 meter = 100 centimeters

Given: 200 centimeters

200 ÷ 100 =

• There are 2 meters is the same as 200 centimeters.
How to convert
• Given: 45 kilometers = __________ meters
• Step 1: Write what conversion you KNOW between inches and feet in the same order as the problem.

Know: 1 kilometer = 1,000 meters

kilometers meters

(big) TO (small)

• If you are going bigger to smaller, you will multiply! x
• If you are going smaller to bigger, you will divide! ÷

Step 3: Set up a math problem using what you know with what you were given.

Know: 1 kilometer = 1,000 meters

Given: 45 kilometers

45 x 1,000 =
