Millimeter to Kilometer Converter

Millimeter

The millimeter (symbol: mm) is a unit of length in the metric system, equal to one thousandth of a meter. Meter, as you know, is the SI base unit of length. Therefore, there are one thousand millimeters in a meter. There are ten millimeters in a centimeter.

One millimeter is equal to 1000 micrometers or 1000000 nanometers. Since an inch is officially defined as exactly 25.4 millimeters, a millimeter is equal to exactly 5⁄127 (≈ 0.03937) of an inch.

The millimeter is often used in day-to-day life for measuring small lengths. For example, pressure is measured in millimeters of mercury (mmHg). A sheet of paper is typically between 0.07 mm and 0.18 mm thick, with ordinary printer paper or copy paper approximately 0.1 mm thick. More information
