A calorie was originally a metric BTU, the amount of energy it took to
raise a gram of water 1 degree c.
They had some inflation when we started using it to describe food so
it became the amount of energy to raise a kg of water one degree c.


That last one is a kilocalorie, often written as Calorie (capitalized).
