Calorie Labels on Food Packaging

Hey all, I'm going to try this Caloric Deficit routine and I have a quick question.

What's the difference between a calorie and a kilo-calorie?

I know - a kilo calorie should mean 1000 calories.

But, for example, I was looking at different types of breads.

Hovis had the calorie count at 109 calories per slice, while Kingsmill had 94 kilo-calories per slice.

Now I find it really hard to believe one slice of Kingsmill has 94000 calories

Am I missing something simple here? Is 94 kilo-calories just another way of saying 94 regular calories? Is there a link between the two?

Thanks for any advice
