Standard Units of Length
Length is measured using standard units. Centimeter (cm) is used for small objects, meter (m) for longer objects like cloth or rooms, and kilometer (km) for very long distances between cities.
Conversion of Meters to Centimeters
To convert meters into centimeters, we multiply the number of meters by 100 because one meter is equal to 100 centimeters.
Conversion of Centimeters to Meters
To convert centimeters into meters and centimeters, we split the given number into hundreds and remaining tens and ones, where the hundreds part becomes meters.
Addition and Subtraction of Lengths
Lengths in meters and centimeters can be added or subtracted by writing them in separate columns, just like regular numbers, making sure to add or subtract centimeters first and then meters.
