why is kilocalorie and calorie used interchangeably?

480 viewsOtherPhysics

From what I understand, kilo is used for a 1000 units of something. Like kilometer is 1000 meters, kilogram is 1000 gram and so on. But when it comes to the food we consume, when we say coconut water has 18 kilocalorie/100 gm, why does it not mean 18000 calorie in general sense?

Does anyone actually use the smaller calories unit for anything as a regular measure of non-food energy things?
