    Study Notes

    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

    Converting Between Meters And Centimeters

    • 1 meter is equal to 100 centimeters
    • To convert meters to centimeters, multiply by 100
    • To convert centimeters to meters, divide by 100

    Converting Between Kilometers And Meters

    • 1 kilometer is equal to 1000 meters
    • To convert kilometers to meters, multiply by 1000
    • To convert meters to kilometers, divide by 1000

    Converting Between Millimeters And Centimeters

    • 1 centimeter is equal to 10 millimeters
    • To convert millimeters to centimeters, divide by 10
    • To convert centimeters to millimeters, multiply by 10

    Everyday Applications Of Length Conversion

    • Measure room lengths in meters
    • Measure book widths in centimeters
    • Measure paper thickness in millimeters
    • Convert between units to solve everyday problems

    Word Problems With Decimals

    • Convert meters to centimeters by multiplying by 100, even with decimals (e.g., 2.5 m = 2.5 x 100 = 250 cm)
    • Convert centimeters to millimeters by multiplying by 10, even with decimals (e.g., 15.2 cm = 15.2 x 10 = 152 mm)
