Food labels
Pet Food Label Calorie Conversions
Convert kcal/kg, kcal/100g, kcal/cup, and kcal/can into usable feeding amounts.
The label unit problem
Pet foods do not all list calories in the same way. One label may say kcal/cup, another may say kcal/kg, and wet food may say kcal/can.
A calculator is only as good as the unit you enter, so converting labels correctly is essential.
Common conversions
If a food lists kcal/kg, divide by 1000 to get kcal per gram. If it lists kcal/100g, divide by 100 to get kcal per gram. If it lists kcal/can, use the can as the portion unit.
- 3500 kcal/kg = 3.5 kcal/g.
- 95 kcal/can means two cans provide 190 kcal.
- 400 kcal/cup means half a cup provides 200 kcal.
- Always check whether the label refers to a cup, kg, 100g, can, pouch, or treat.
Mixed feeding example
If a pet needs 500 kcal/day and you want 40% from wet food, that is 200 kcal wet and 300 kcal dry. Divide each part by that food's calorie unit.
This method avoids accidentally adding wet food on top of a full dry-food ration.
Why calories are not the whole diet
Calories help with portion size, but they do not prove a diet is nutritionally appropriate. Life stage, complete-and-balanced labeling, health status, and veterinary recommendations still matter.

FAQ
What if my label has no calories?
Check the manufacturer's site or contact them. Avoid guessing for precise feeding plans.
Is kcal the same as Calorie?
In pet food labeling, kcal is the practical food calorie unit owners use for feeding math.
Can two cups of different foods have different calories?
Yes. Kibble density and formulation can make a large difference.
