Teaspoons is a much more widely known quantity in the US than grams.
Youre making a cake, not an explosive compound.
People understand what a teaspoon is. No one understands the metric system.-John Oliver (Just kidding but it's kind of true in the U.S)
We need to be more precise, so go metric on this one.
Death to the imperial system!
Nutrition facts should be more accurate than that. FreedomBeforeEquality would be right, except the question was about nutrition facts on the side of labeling, not a cake or similar recipe- a recipe can be either, nutrition facts should be more professional, since it's company made.
More precise. More of the world uses it.
