The millimeter (mm) is a metric unit of length equal to one-thousandth of a meter. It is the working unit of engineering drawings, precision manufacturing, electronics, and most consumer-goods specifications outside the United States. A credit card is about 0.76 mm thick; the diameter of a pencil lead is around 2 mm.
The meter (m) is the SI base unit of length. Defined since 2019 as the distance light travels in vacuum in exactly 1/299,792,458 of a second, the meter is the reference all other length units derive from. It is the standard unit for room dimensions, sports fields, and short-to-mid distances in most of the world.
