Worked example: a 20-ounce bottle of soda

A 20 oz bottle of regular cola carries about 65 g of added sugar. Type 65 into the calculator. First step, grams to teaspoons: 65 / 4 = 16.25, displayed as 16.3 tsp. Second step, the daily-limit share: 65 / 50 = 1.3, so the tool reports 130% of the 50 g limit, with no tilde, because the result is at or above the full limit.

Run the same math on a 12 oz can at 39 g: 39 / 4 = 9.75 tsp, and 39 / 50 = 0.78, or 78% of the limit. That single can is three quarters of the entire daily budget before breakfast, dessert, or anything else counts. If you halve the serving instead, 19.5 g / 4 = 4.9 tsp and 39% of the limit, which shows how serving size, not the drink type, moves the number most.

Where the estimate breaks down

The 4 g per teaspoon conversion is a density approximation for granulated sugar, and liquid sugars in syrup weigh slightly differently, so real teaspoons can vary by up to 10% either way. A 39 g can is honestly 9.4 to 10.1 tsp, not exactly 9.75. The tool rounds to one decimal, which looks more precise than the physics justifies.

Labels round too: anything under 0.5 g per serving prints as 0 g, so a drink with 0.4 g per serving listed at 8 servings in the bottle is 3.2 g total even though the label shows zero. The 50 g limit is the FDA Daily Value for added sugar, calibrated to a 2,000-calorie diet for anyone age 4 and up; children under 4 have no established DV, and the American Heart Association suggests tighter budgets of 25 g for most women and 36 g for most men. Finally, the calculator counts what you enter as added sugar: if you paste in a label line that already includes naturally occurring sugar from milk or fruit, the limit share will be overstated.
