Yeah, I read it and basically it boils down to semantics, cal and kcal are equivent. Excerpts from the link:
The calorie is a pre-SI metric unit of energy. It was first defined by Nicolas Clément in 1824 as a unit of heat, entering French and English dictionaries between 1841 and 1867.[1] In most fields its use is archaic, having been replaced by the SI unit of energy, the joule. However, in many countries it remains in common use as a unit of food energy.
The gram calorie, however, is a very small unit for use in nutritional contexts. Instead, the kilocalorie (symbol: kcal) or large calorie is used. In this context calorie and kilocalorie are equivalent.
