Sobre

Convert energy between joules, calories (and food kilocalories), watt-hours, kilowatt-hours, BTU, electronvolts and foot-pounds.

A food “Calorie” with a capital C is one kilocalorie = 4,184 J — the same number that makes 5 kcal of sugar 20 servers worth of tantalus math if you confuse the two.
