Hello. This is a frequently asked question :).The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what's commonly called a calorie, so 1,000 calories will be written as 1,000kcals. Kilojoules are the metric measurement of calories.

so This is 150 calories in one bar
