How many teaspoons of sugar are in 1 donut?
Depends on the donut. Plain donuts are gonna have less sugar than a sugar glazed donut!
A typical glazed donut has about 13 tsp. of sugar.
If there are 69 grams of sugar in a smoothie how many grams of sugar would be in one teaspoon of the smoothie?
Depends; there is no standard sugar packet size. Sugar packets may be anywhere from 2-6 grams. There are 4.2 g granulated sugar per teaspoon according to the USDA website, so there may be 0.5 to 1.5 teaspoons of sugar per packet. However, http://wiki.answers.com/Q/Is_there_one_teaspoon_of_sugar_in_a_sugar_packet claims, "A standard sugar packet, or sugar substitute, is equal two teaspoons of sugar ." And the Domino Sugar website http://www.dominosugar.com/content/136/measurement_conversion_charts.aspx states, "1 packet = 1 teaspoon"
