Cat feeding math
Dry cat food grams calculator
Convert dry cat food calories into grams per day or grams per meal using kcal per cup, kcal per 100g or kcal per kg from the label.
Why grams beat cups
Cups are convenient but imprecise. Kibble shape and scoop technique change the amount. If you can weigh dry food in grams, the portion becomes much more repeatable.
Which label number to use
If the bag lists kcal/kg, divide by 1000 to get kcal per gram. If it lists kcal/100g, divide by 100. If it only lists kcal/cup, weigh one level cup once, then BowlMath can estimate grams from cup calories.
Daily grams vs meal grams
Calculate the daily dry food grams after wet food and treats are counted. Then divide by meals per day so each serving is easy to repeat.
Quick answers
How do I convert kcal/kg to kcal/g?
Divide kcal per kg by 1000. A food with 3800 kcal/kg is 3.8 kcal per gram.
Are grams better than measuring cups?
Usually yes. Grams are more consistent, especially for small cat portions.
Important: BowlMath gives a practical starting estimate, not veterinary advice. Ask your veterinarian before changing portions for kittens, seniors, pregnant or nursing cats, diabetic cats, cats on therapeutic diets, or cats gaining/losing weight unexpectedly.
