So 50 grams of added sugar ≈ 12 teaspoons ≈ 12–13 cubes.
Each gram of sugar is about 4 calories.
Nutrition labels list sugar in grams, but almost nobody thinks in grams. Converting to teaspoons or sugar cubes makes the numbers suddenly vivid.
The key conversions
A few simple ratios unlock every sugar number:
1 teaspoon of sugar ≈ 4 grams
1 sugar cube ≈ 4 grams (about one teaspoon)
1 gram of sugar ≈ 4 calories
So to turn grams into teaspoons, divide by four. A drink with 40 grams of sugar contains about 10 teaspoons — or 10 sugar cubes stacked on the counter.
Putting the daily limit in view
The FDA's 50-gram daily value for added sugars is about 12 teaspoons or 12–13 cubes. The American Heart Association's tighter 25-gram target for women is about 6 teaspoons. Picture those cubes and the limits feel much more concrete.
Common drinks in cubes
12-oz soda (39g): ~10 cubes
Full-sweet boba (50g): ~12–13 cubes
Large blended coffee (60g): ~15 cubes
Plain latte (0g added): 0 cubes added
Why calories follow
Since each gram of sugar is about 4 calories, 40 grams of sugar is roughly 160 calories — all of it 'empty' if it's added sugar with no accompanying nutrients. This is the math behind why sugary drinks add up so fast on the calorie side too.
The BevFacts app shows your drink's sugar as a row of sugar cubes, so the grams on the label become something you can actually picture.
