What is decimetre?
The decimetre (dm) is a metric unit equal to one tenth of a metre or 10 centimetres. While less commonly used in everyday life, it appears in scientific contexts and in some European countries for measuring small distances.
What is millimetre?
The millimetre (mm) is a metric unit equal to one thousandth of a metre. It is widely used in engineering, manufacturing, and medicine for precise measurements. Standard paper thickness is typically measured in millimetres.
