which unit is used to measure mass in the metric system UNANSWERABLE what is this system? It  is a system of measurement that succeeded the decimalised system based on the metre introduced in France in the 1790s. what are some of its common ones? Mètre des Archives and Kilogramme des Archives what is the emu system? Several systems of electrical units were defined following discovery of Ohm's law in 1824. what are the prefixes used here? In the metric system, multiples and submultiples of units follow a decimal pattern and in the early days, multipliers that were positive powers of ten were given Greek derived prefixes such as kilo and mega and those negative were given centi and milli. what does gravitational system uses? It uses  the kilogram-force (kilopond) as a base unit of force, with mass measured in a unit known as the hyl, "Technische Masseneinheit" (TME), mug or metric slug.

The tonne-force, metric ton-force, megagram-force, and megapond (Mp) are each 1000 kilograms-force. The decanewton or dekanewton (daN), exactly 10 N, is used in some fields as an approximation to the kilogram-force, because it is close to the 9.80665 N of 1 kgf.
