A calorie is a unit of heat (energy in transit) and it equals 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.
