What is a kilocalery?

Answer 1

A kilocalorie is one food calorie. A standard calorie is a unit of energy equal to 4.184 joules. This is a very small amount of energy, so when we're talking about the amount of energy in food, we use kilocalories, which is equal to 1000 standard calories. When we're talking about food, we always say that it has so many calories, but forget to note that we're talking about food calories, which makes it somewhat confusing. 1 standard calorie= 4.184 joules 1000 standard calories= 1 kilocalorie= 1 food calorie= 4184 joules If a piece of food has 80 (food) calories, then it has 80 kilocalories, or 80,000 standard calories.
