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.
What is metre?
The metre (m) is the base unit of length in the International System of Units (SI). Originally defined as one ten-millionth of the distance from the equator to the North Pole, the metre is now defined by the speed of light in vacuum. It is used worldwide for everyday measurements, construction, and science.
