In microeconomics, this problem is less evident as we may be able to observe say, the price of 1.5 litre of coke is say $2. In macroeconomics however, do we know what "national product" means? What exactly is price level? Whose price level should we use as a guage? What is the meaning of money? These issues are rather complex.
