How many grams is half a teaspoon of instant coffee?
One teaspoon of instant coffee weighs about 0.896 grams and one tablespoon is about 2.69 grams, so half a teaspoon comes out to roughly 0.448 grams. Instant coffee is light and fluffy: a level teaspoon is only about 0.9 g, so a level cup comes to roughly 43 g. Most people scoop it rounded, which USDA puts nearer 1.8 g a teaspoon — so 2 g is about one rounded teaspoon. It is lighter than espresso powder, so use a little more if you swap it into baking.
Small spoon amounts are where weighing has the biggest payoff: tiny errors compound in baking. If your scale reads in 1-gram steps you can measure instant coffee directly. (For reference, one US cup is 43 g.)
