How do you calculate k cal per cup of dog food?

To calculate kilocalories (kcal) per cup of dog food, first check the food's packaging for its calorie content, usually expressed as kcal per kilogram (kg) or kcal per 100 grams. If the calorie content is given per kg, divide that number by 4.54 (the number of kg in a pound) to get kcal per pound. Then, determine the weight of one cup of the dog food in pounds (or grams) and multiply that weight by the kcal per pound (or kcal per gram) to find the total kcal per cup.
