1. What is the SI unit designation?A derived unit of length in the International System of Units (SI)
2. What is the metric relationship?Equivalent to 10⁻² metres (one hundredth of a metre)
3. Why do we use centimetres instead of metres or millimetres?Centimetres give a good balance: metres can be too big with long decimals, and millimetres can be too precise for everyday use. They fit well for things like human height, furniture, and many parts in machines.
4. How big is a centimetre compared to a metre?One metre is made up of 100 centimetres. So a centimetre is one part of a hundred in a metre.
