About cinnamon, powder measurements
Ground cinnamon is light and fluffy — a reference density near 0.56 g/ml, only about 8 g per tablespoon. Freshly milled bark is airier and weighs less by the spoon than fine, long-stored powder that has settled and clumped, so a heaped spoon of old cinnamon can carry surprisingly more.
