Standard Units of Length
We use centimeters (cm) for small objects like pencils, meters (m) for larger things like room length, and kilometers (km) for very long distances between cities.
Conversion between Meters and Centimeters
Since one meter is equal to 100 centimeters, we multiply by 100 to convert meters to centimeters, and divide or split to convert centimeters into meters and centimeters.
Measuring with a Ruler
To measure an object, align one end with the 0 mark on the ruler and read the number where the other end stops.
Addition and Subtraction of Lengths
To find total length or the difference between two lengths, we add or subtract meters with meters and centimeters with centimeters separately.

Frequently Asked Questions
How do I convert meters into centimeters?
To convert meters into centimeters, multiply the given meter value by 100.
Should I write units like 'cm' or 'm' in my final answer?
Yes, always include the correct unit (cm, m, or km) in your final answer, otherwise marks may be deducted.
When do we use kilometers instead of meters?
We use kilometers to measure very large distances, such as the distance between two towns or schools.
