Is there a difference between a kcal and a calorie? If so, what? Thanks!

    Really, what we usually call calories are kilocalories.

    What is the difference between calories and kilocalories? The "calorie" we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie (upper case C). A kilocalorie is the amount of heat required to raise the temperature of 1 kilogram of water one degree Celsius.

    So kilocalories is the correct term, shortened to "kcal"?

    calorie = the amount of energy needed to raise the temperature of one cubic centimeter (1mL) of water by one degree Celsius.
    Calorie = kilocalorie = the amount of energy needed to raise the temperature of 1,000 cubic centimeters (1L) of water by one degree Celsius. This is what people mean when referring to a food calorie.

    In a more scientific context, it would be a better term to use. In this context, it's often just confusing for no real benefit not to use "calorie." I guess it depends on whether you want to be scientifically or idiomatically correct.

    I mean, yeah, a tomato is scientifically a fruit, but...

    I prefer the word "calorie" instead of "kcal" because that's how I grew up. And yes, wisdom is knowing that a tomato is a fruit, but common sense knows that you don't include it in a fruit salad . . .

    Stick with "calorie," then. People will know what you mean and if you run across kilocalorie, kcalorie, or kcal, you'll know it's the same thing as your "calorie."
