What is the use of millimeters?
Usage context: Millimetres are used as a standard measure of length in all manner of engineering and commercial applications where accuracy greater than the closest centimetre is required. Where even greater accuracy must be measured or expressed, fractions of a millimetre are used to three decimal places.
What unit is used to express multiples of a millimeter?
There are numerous units for expressing multiples of the millimetre, but these are defined by their relationship to the metre (the SI base unit of length), rather than the millimetre.

Overview
The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre. There are ten millimetres in a centimetre.
One millimetre is equal to 1000 micrometres or 1000000 nanometres. Since an i…
Definition
Since 1983, the metre has been defined as "the length of the path travelled by light in vacuum during a time interval of 1/299792458 of a second". A millimetre, 1/1000 of a metre, is therefore the distance travelled by light in 1/299792458000 of a second.
Informal terminology
A common shortening of millimetre in spoken English is "mil". This can cause confusion since in the United States, "mil" traditionally means a thousandth of an inch.
Unicode symbols
For the purposes of compatibility with Chinese, Japanese and Korean (CJK) characters, Unicode has symbols for:
