Morphology

kilocalorie = calorie (transparent) = kilo + calorie + kilo

The meaning is the straightforward numeric prefix 'kilo-' (thousand) applied to the unit 'calorie', yielding 1,000 calories.

Etymology

Kilocalorie joins kilo- meaning 'thousand', as in kilometer, with calor meaning 'heat', which is the base of the word calorie. So a kilocalorie is like a 'thousand heat' unit of energy — the amount needed to warm one kilogram of water by one degree Celsius — and that is why food labels often call it a 'Calorie' to show how much energy is in food.
