Explanation:
Every measurement has two parts. The first is a number (n) and the next is a unit (u). Q = nu. For Example, the length of an object = 40 cm. The number expressing the magnitude of a physical quantity is inversely proportional to the unit selected.
If n1 and n2 are the numerical values of a physical quantity corresponding to the units u1 and u2, then n1u1 = n2u2. For Example, 2.8 m = 280 cm; 6.2 kg = 6200 g.
