When combined with the base unit meter (symbol m), the resulting abbreviation is mm—milli‑meter. This concise representation is favored in scientific, engineering, and everyday contexts because it reduces space and improves readability, especially in tables, schematics, and technical documentation.
In contrast, the use of “MM” for million stems from Roman numerals, where “M” stands for mille (thousand). Consider this: doubling it (“MM”) clarifies the magnitude of a thousand thousands, i. e., one million.
