i see, so if a food lable has 485 kcal per 100g, then that means for every 100g of that food i eat im consuming 485,000 calories? that cant be right or do i divide it to get 0.485... that looks wrong too... im confuddled O_o

It's easier for the general public to understand, because they aren't seeing all those zeros. We had a discussion on it in my biochemistry class a while back.. a calorie is actually very small, whereas a Calorie is what is on the nutrition labels. . just like the above posts stated. Not to mention this standard saves ink.

aaaaah, (light bulb lights up above head, flickers a bit then goes out) i think i get it now! ur sayin a calorie as us simpleminded folk know it, and a kcal are one and the same. so my malteaser which are 485kcal per 100g are 485 calories per 100g! why didnt ya just say that to begin with!!!

A calorie is 4.184 joules or the amount of energy it takes to raise the temperature of one gram of water from 15 to 16 degrees Celsius (or 1/100th the amount of energy needed to raise the temperature of one gram of water at one atmosphere pressure from 0 degrees C to 100 degrees C). Theseare used in physics/chemistry.
Food Calories are actually equal to 1,000 calories (1 food Calorie = 1 kilocalorie or 4.184 kilojoules). One Calorie is the amount of energy needed to raise the temperature of a kilogram of water the same amount as described above.
1000 calories = 1 Calorie
