Calculate the carbohydrate % of any beverage: To calculate the carbohydrate concentration of any beverage as a percentage, divide the amount of carbohydrate in one serving (in grams) by the amount of fluid in one serving (in milliliters), and then multiply by 100 (8 ounces equals 240 milliliters).

For Gatorade: 14 grams carbohydrate x 100 = 5.83 or 6% carbohydrate concentration 240 milliliters
