The EU should use Joules not calories - Lemmy Português

Joule is the metric system unit to measure the energy in food, however we still see calories being used everywhere, specially advertising and fitness influencers. Let’s stop this nonsense.

Why? It is quite a round number. 1 calorie raises the temperature of 1 gram of water by 1 degree

And how do you convert that to mechanical or electrical energy?

Why would I need the energy of a biscuit as electrical energy? In a case like that I guess that I’ll multiply by 4.whatever and get joules.

Counter question: Why would I need to know how many grams of water I can raise the Temperature by one degree with the food I eat?

For the same practical reason I would need the mechanical energy of a carrot.

Wait wait, I got it! How many biscuits do I need to burn to boil the carrot?
