    The small calorie or gram calorie (symbol: cal)[2] approximates the energy needed to increase the temperature of 1 gram of water by 1 °C. This is about 4.2 joules.

    The large calorie, kilogram calorie, dietary calorie or food calorie (symbol: Cal)[2] approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C. This is exactly 1,000 small calories or about 4.2 kilojoules.

    Basically a kcalorie = kcal = Calorie

    if it is a lower case c, that's 1000 regular Calories that we use and was probably typed wrong.

    To clarify all this mumbo jumbo, the calories you're used to seeing reported on food and this site are kCals. Small calories (cal) are too small of a unit to be useful for measuring food energy.
