Why do food packages carry Kcal when they actually specify calories and not kilo-calories?

Kilocalories are commonly known as calories and abbreviated as kcal. One calorie (Kcal) has the same energy value as 4.186 kilojoules (kJ), while one kilojoule is equivalent to 0.24 calories. One calorie contains the amount of energy that raises the temperature of one litre of water by 1 degree Celsius.
