How many grams is one teaspoon of instant coffee?
One teaspoon of instant coffee weighs about 0.896 grams and one tablespoon is about 2.69 grams, so one teaspoon comes out to roughly 0.896 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.)
