Unit definitions

What is a meter?

The metre is the SI base unit of length, defined since 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second. It underpins every other metric length unit and is the global standard for science, construction, and international trade.

What is a millimeter?

The millimetre is one thousandth of a metre, an SI unit of length. It is the finest gradation on most metric rulers and is standard for engineering drawings, machining tolerances, and rainfall measurement. Ten millimetres make one centimetre.
