Why is a unit of charge in emu equal to that in mks?

Where I come from, the words charge and emu in the one sentence can only mean one thing these days. read more

The tesla (note that symbols names in SI are always in lower case in English, except for degree Celsius in which Celsius is regarded as a descriptive adjective for a unit rather than the main unit itself) is an electromagnetics unit, not a mechanics unit derived from the 3 mks base units. read more

In another variant of the CGS system, electromagnetic units (EMU), current is defined via the force existing between two thin, parallel, infinitely long wires carrying it, and charge is then defined as current multiplied by time. read more

The MKS unit of force, the newton, is the force which accelerates a mass of one kilogram at the rate of one meter per second per second. Since the meter equals 100 centimeters and the kilogram equals 1000 grams, the ratio between a CGS unit and the corresponding MKS unit is characteristically a power of 10. read more
