Because everything must all be in the same unit system, e.g. Imperial, or metric (SI). You can't do any arithmetic like adding or multiplying on two numbers in different unit systems. For example, you can't add 100 km to 100 mi. The answer wouldn't make any sense. First you must convert one to the other, either miles to km or km to miles and so the result to would from 100 mi + 60 mi (approx. 100 km) = 160 mi.
