Convert grams of sugar on labels to teaspoons of sugar

Convert grams of sugar on labels to teaspoons of sugar   (05/09/2014, 9:27 PM)

I am trying to figure out how much sugar is in many foods. I measure in teaspoons or tablespoons so grams of sugar on a food label means nothing to me. Can you tell me how to convert it so I can figure out how much sugar is in a food. Thanks
