In the United States and Canada, in a nutritional context, the “large” unit is used almost exclusively.
In the European Union, on nutrition facts labels, energy is expressed in both kilojoules and kilocalories, abbreviated as “kJ” and “kcal” respectively.
Why is this downvoted? 1kcal = 1000 cal. So 2500kcal = 2500 * 1000 cal.
It is, which is only 2,500 Calories (like, the ones on food)
It’s a crappy system where kcal and Calories are the same thing even though they sound like they are off by a factor of 1000

Yes, 2500 Calories with a capital C. 2500 Calories = 2 500 000 calories. So the correction is valid, but for some reason being downvoted.
Probably because it’s unnecessary and pedantic. No one is confused when someone is technically incorrect and types “calories” when talking about food.

So yeah, it’s confusing if you’re not American.
