Centimetre–gram–seicont seestem o units

The centimetre–gram–seicont seestem o units (abbreviatit CGS or cgs) is a variant o the metric seestem based on the centimetre as the unit o lenth, the gram as the unit o mass, an the seicont as the unit o time. Aw CGS mechanical units are unambiguously derived frae thir three base units, but thare are several different weys o extending the CGS seestem tae cover electromagnetism.
