About
Gelatin powder is a dry gelling agent made from animal collagen, packing about 5.4 ounces (154 grams) per cup.
Gelatin powder has a typical bulk density of about 5.4 ounces per cup (0.65 grams per milliliter). Because of its small, hard granules, it packs more weight into the same space than fluffy baking ingredients like cocoa or powdered sugar. It remains less dense than table salt or white sugar, which have heavier, closer-fitting crystals. In recipes, a small volume of this dry powder can set several cups of liquid into a firm gel.
From Wikipedia
Gelatin in American English or gelatine in British English is a translucent, colorless, flavorless food ingredient, commonly derived from collagen taken from animal body parts. It is brittle when dry, and rubbery when moist.
