Why is the metric system known as the international system measurement?
All derived units use a common set of prefixes for each multiple. “Kilo” means 1000 whether it is used both for mass (kilogram) or length (kilometre). A few units such as the tonne (megagram) and quintal (100 kilograms) survive from old units but have been rounded to metric. The prefixes which come from the Greek language (kilo, mega, giga) are multipliers and those with Latin origins (centi, milli) are divisors.
