Daily carbohydrate target in grams, from your total calories and a target carb percentage.
Carbohydrate provides about 4 calories per gram, so dividing the calories allotted to carbs by 4 converts that calorie amount into grams.
That's the Acceptable Macronutrient Distribution Range for carbohydrate as a share of total daily calories — a general population guideline, not a target tailored to your specific goals.
The Macro Calculator splits your calories across protein, carbs and fat together (requiring all three percentages to add to 100%). This page focuses on carbs alone against a single AMDR benchmark.
