About
Caffeine powder is a concentrated stimulant that weighs about 4.6 ounces (130 grams) per cup.
Caffeine powder has a typical bulk density of about 34 pounds per cubic foot (0.55 grams per milliliter). This makes it much lighter and fluffier than granulated sugar, falling closer to the density of sifted flour or cocoa powder. Because it is a loose powder, light tapping or settling can easily change how much fits in a given scoop. Even a small physical volume contains a huge concentration, meaning a single cup holds hundreds of typical daily servings.
