From this unit dimensions measurement equation, the CGS unit of force = gm × (cm/sec2) = gm cm sec-2or simply dyne and SI unit of force = Kg × (m/sec2) = Kg m sec-2or simply newton. Use of the SI unit, the candela, is preferred. The centimetre–gram–second system of units (abbreviated CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time.All CGS mechanical units are unambiguously derived from these three base units, but there are several different ways in which the CGS system was extended to cover electromagnetism. Units of Specific Heat. The imperial/U.S. Historically Rydberg units have been used. The energy unit used for everyday electricity, particularly for utility bills, is the kilowatt-hour (kWh), and one kWh is equivalent to 3.6×106 J (3600 kJ or 3.6 MJ). The Hartree (the atomic unit of energy) is commonly used in calculations.
