The units, excluding prefixed units, form a coherent system of units, which is based on a system of quantities in such a way that the equations between the numerical values expressed in coherent units have exactly the same form, including numerical factors, as the corresponding equations between the quantities. The SI units of measurement are based on seven quantities, other commonly used quantities are derived from these. Some other units are not derived SI units but commonly accepted, such as the litre. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units. When Maxwell first introduced the concept of a coherent system, he identified three quantities that could be used as base units: mass, length and time. thumb_down_alt 0 dislike. temperature, symbol T, in terms of its difference from the reference asked May 6, 2018 by anonymous.
