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?
