What is the difference between the cuystomary english system and the metric system of 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.
