Pet food labels show nutrient percentages, but what really matters is how many grams your pet actually eats. Use this tool to convert pet food percentages to grams based on portion size and calorie content.
Learn more about interpreting guaranteed analysis in our article Interpreting Guaranteed Analysis: Beyond Percentages.
How to Use
Enter the percentage of each nutrient as shown on the food label, the number of calories per kilogram, and the recommended portion size (in grams). The calculator will convert those percentages into actual grams of nutrients your pet gets in that portion—plus show how many calories the portion provides.
Use it to compare two foods side by side and make smarter decisions based on what your pet actually eats, not just what’s listed on the label.
