one dimensional vs two dimensional

It is often necessary to convert one set of units to another. This can be done in a systematic way by the method called dimensional analysis or the conversion factor method. Conversion factor is equal to the ratio of the magnitudes of the same quantity in the two unit..

Dimensional formula - It is the term which tells about the power with which a fundamental quantity is contained in a physical quantity. E.g., Dimensional formula of velocity is [LT - 1 ], that of density is [ML - ..

Dimensional analysis has no information on dimensionless constants. If a quantity is dependent on trigonometric or exponential functions, this method cannot be used. In some cases, it is difficult to guess the factors while deriving the relation connecting two or more ph..
