Understanding Centimetres and Metres: A Comprehensive Guide
In the world of measurement, centimetres and metres are fundamental units used in various aspects of life, from daily tasks to scientific research. Understanding the relationship between these two units and how to convert between them is essential. This blog explores what centimetres and metres are, their uses, and how to teach these concepts effectively, especially through outdoor learning.
What are Centimetres?
A centimetre (cm) is a unit of length in the metric system. It is equal to one-hundredth of a metre. The term “centimetre” is derived from the Latin words “centum” (meaning one hundred) and “metrum” (meaning measure).
Key Facts about Centimetres:
- 1 centimetre = 0.01 metres
- 100 centimetres = 1 metre
- Commonly used for measuring smaller objects and distances

What are Metres?
A metre (m) is the base unit of length in the International System of Units (SI). It is widely used globally for measuring length and distance. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole.
Key Facts about Metres:
- 1 metre = 100 centimetres
- Used for measuring larger distances and objects
- Standard unit for scientific and everyday measurements

Converting Between Centimetres and Metres
Understanding how to convert between centimetres and metres is straightforward:
- To convert from centimetres to metres, divide by 100 (e.g., 150 cm = 1.5 m).
- To convert from metres to centimetres, multiply by 100 (e.g., 2 m = 200 cm).
