About this calculator

This calculator finds a daily carbohydrate gram target by taking a percentage of total daily calories and dividing by 4, since carbohydrates provide 4 kilocalories per gram — the same conversion nutrition labels use.

It's used by people following a specific macro split like keto (very low carb) or a standard 45–65% carb diet, by athletes tuning carb intake around training, and by people managing diabetes who need to keep carb grams within a target range per meal or per day.
