Dog food cups to grams converter
Convert cups of dry dog food to grams, or grams to cups, for your particular kibble. Use the two calorie numbers printed on the bag, or weigh one level cup on a kitchen scale.

Grams per cup = 380 kcal per cup ÷ 3,600 kcal per kg × 1,000 = 105.6 g. 1 cups × 105.6 g = 106 g.
Results apply to dry kibble measured with a level 8 oz cup. Weighing your food is always the most accurate method.
How many grams are in a cup of dog food?
A cup measures volume, not weight, so the answer depends on your kibble. Small, dense pieces pack more grams into a cup than big, airy ones. The good news is that your bag already holds the answer. AAFCO rules require a calorie statement in kcal per kilogram and in kcal per familiar unit such as a cup, and dividing one by the other gives the weight of a cup.
Grams per cup = kcal per cup ÷ kcal per kg × 1,000
Worked example: a kibble labelled 3,600 kcal/kg and 380 kcal/cup weighs 380 ÷ 3,600 × 1,000 = 106 g per cup, or about 3.7 oz. That is 4.3 cups per pound and 9.5 cups per kilogram.

Three made-up labels show how much the answer moves: from 91 g per cup for a light kibble to 118 g for a dense one. Find your own food's numbers with the converter.
| Cups | 91 g/cup (310 kcal/cup, 3,400 kcal/kg) | 106 g/cup (380 kcal/cup, 3,600 kcal/kg) | 118 g/cup (450 kcal/cup, 3,800 kcal/kg) |
|---|---|---|---|
| ¼ cup | 23 g | 26 g | 30 g |
| ½ cup | 46 g | 53 g | 59 g |
| ¾ cup | 68 g | 79 g | 89 g |
| 1 cup | 91 g | 106 g | 118 g |
| 1½ cups | 137 g | 158 g | 178 g |
| 2 cups | 182 g | 211 g | 237 g |
| 2½ cups | 228 g | 264 g | 296 g |
| 3 cups | 274 g | 317 g | 355 g |
| 4 cups | 365 g | 422 g | 474 g |
Converting grams to cups
The same number works in reverse. Feeding guides on European bags, and many vet diet plans, give daily amounts in grams. To turn grams into cups, divide by the grams in one cup: a plan of 250 g a day of the 106 g-per-cup food above is 250 ÷ 106 = 2⅜ cups. European labels often state energy per 100 g instead of per kg; multiply it by 10 before using the formula. If the label gives no calories per cup at all, weigh a cup instead.
How to weigh a cup of your dog's food
If your label doesn't give both numbers, or you want to check, a kitchen scale takes two minutes:
- Put an empty bowl on the scale and set it to zero.
- Fill a standard 8 oz dry measuring cup with kibble, level it off with a straight edge, and tip it into the bowl.
- Read the grams. Repeat two more times and take the average, since no two scoops are quite the same.
- Enter that number under "I weighed it" in the converter.
Weigh again whenever you change food, because a new recipe or kibble size changes the answer.
Why measuring cups are inaccurate
Researchers have tested this. In a 2011 study by German and colleagues, portions measured with cups ranged from 18% under to 80% over the intended amount. In a 2019 University of Guelph study of 100 dog owners, errors ranged from about 48% too little to 152% too much, and small amounts such as a quarter cup were the hardest to get right. The device mattered as well: a one-cup dry measuring cup did better than a two-cup liquid measure or a commercial scoop. The Guelph team recommended weighing food on a gram scale instead.
Switching your dog's food from cups to grams
To move from scooping to weighing, convert your dog's current daily cups to grams once, then weigh that amount at every meal. If you are not sure the current amount is right, start from your dog's calorie needs with the dog feeding calculator, which works in cups or grams. Knowing the grams also makes the bag calculator exact, since a bag is sold by weight. The Merck Veterinary Manual notes that the same calorie statement also lists energy per can for wet food, so canned food can simply be portioned by the can.
Frequently asked questions
How many grams is 1 cup of dog food?
There is no single answer, because kibbles differ in size, shape and density. Work it out from your bag: divide the kcal per cup by the kcal per kg and multiply by 1,000. A food labelled 3,600 kcal/kg and 380 kcal/cup has about 106 g in a cup. Or weigh one level cup on a kitchen scale.
How many cups are in a pound of dog food?
Divide 454 g (one pound) by the grams in one cup of your food. At 106 g per cup that is about 4.3 cups per pound; a lighter kibble gives more cups per pound and a denser one fewer.
Is the scoop that came with my dog food the same as a cup?
Not necessarily. Scoops come in all sizes, and in a University of Guelph study owners using a commercial scoop or a two-cup graduated liquid measure were less accurate than with a one-cup dry measuring cup, so weigh your scoop's contents once if you use one.
Why does my dog food bag list kcal per cup but not grams per cup?
AAFCO rules require the calorie statement to give both kcal per kg and kcal per familiar unit such as a cup, but not the cup's weight. Those two numbers are enough to work it out, which is what the converter does.
