Converting Units of Length

Converting Between Meters And Centimeters

• 1 meter (m) = 100 centimeters (cm)
• To convert meters to centimeters, multiply by 100
• To convert centimeters to meters, divide by 100

Examples:

• 5 m = 5 x 100 = 500 cm
• 250 cm = 250 ÷ 100 = 2.5 m

Kilometers To Meters

• 1 kilometer (km) = 1000 meters (m)
• To convert kilometers to meters, multiply by 1000
• To convert meters to kilometers, divide by 1000

Examples:

• 3 km = 3 x 1000 = 3000 m
• 4500 m = 4500 ÷ 1000 = 4.5 km

Millimeters To Centimeters

• 1 centimeter (cm) = 10 millimeters (mm)
• To convert millimeters to centimeters, divide by 10
• To convert centimeters to millimeters, multiply by 10

Examples:

• 50 mm = 50 ÷ 10 = 5 cm
• 7 cm = 7 x 10 = 70 mm

Converting Units Of Length In Everyday Situations

• Real-world examples:
  • Measuring the length of a room (meters)
  • Measuring the width of a book (centimeters)
  • Measuring the thickness of a paper (millimeters)
• Convert between units to solve problems in everyday situations

Word Problems Involving Length Conversion With Decimals

• Examples:
  • A bookshelf is 2.5 meters long. How long is it in centimeters?
    • 2.5 m x 100 = 250 cm
  • A pencil is 15.2 centimeters long. How long is it in millimeters?
    • 15.2 cm x 10 = 152 mm
• When converting between units with decimals, follow the same conversion rules as above
• Be careful when working with decimals to ensure accurate conversions
