In finance and accounting, MM (or lowercase “mm”) denotes that the units of figures presented are in millions. Thus, MM is the same as writing “M multiplied by M,” which is equal to “1,000 times 1,000”, which equals 1,000,000 (one million). In these countries millimeters are the preferred unit for measuring dimensions of building materials, such as pipes, beams, and panels. Millimeters are found in manufacturing for precision measurements, machinery, and tools. Millimeters are also used in medicine and are used in the fashion and textile industry.

Millimeters are a unit of measurement commonly used in the metric system to quantify lengths and distances. The term “millimeter” is derived from the Latin words “milli,” meaning one thousandth, and “metrum,” meaning measure. As the name suggests, a millimeter is equal to one thousandth of a meter, making it a very small unit of measurement. Under the metric system of measurement, the commonly used units of distance are millimeters (mm), centimeters (cm), meters (m), and kilometers (km).
