Energy and Calories

The latter is an obsolete unit for energy anyway. The SI unit is Joules. 1 J = 1 N * 1 m = 1 kg * 1 m²/s² = etc etc – see that’s the whole idea of the SI system – you don’t have any coefficients.

Yet using Calories further makes it easier to construct misconceptions like the advertisement for Hydrive energy drinks: they give you lots of energy and are healthy because they have low Calories.
