A calorie is a unit of heat or energy and it equal about 4.2 J where 1J = 1 kg m^2 s^-2 . Suppose we employ a system of units in which the unit of mass equals alpha kg, the unit of length equals beta m, the unit of time is gamma s. Show that a calorie has a magnitude 4.2 alpha^-1 beta^-2 gamma^2 in terms of the new units.
