One tablespoon of sugar is equivalent to 12 grams. Each tablespoon is equivalent to three teaspoons, or 4 grams of sugar. When looking at food labels, sugar is measured in grams, while daily intake levels are typically measured in teaspoons.
The American Heart Association recommends that women consume no more than 6 teaspoons of added sugar and men limit consumption to 9 teaspoons of added sugar daily. To convert the gram measurement on food labels to teaspoons, divide the amount of sugar listed by four. Added sugars come in many different forms, including corn syrup, molasses, honey, brown sugar, malt sugar and a variety of sugar molecules ending in "-ose."
