Measuring Ground Cinnamon Accurately
Why weight matters: 1/3 cup of ground cinnamon can weigh anywhere from 34g to 48g depending on how you measure it. The USDA standard is 39.67g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About ground cinnamon density: Ground cinnamon is a light, fine powder. 1 teaspoon = 2.5g. Ceylon and Cassia cinnamon weigh the same per volume. Most "cinnamon" in US stores is Cassia. Freshly ground sticks weigh slightly more per volume.
About 1/3 Cup as a Measurement
1/3 cup = 5 tablespoons + 1 teaspoon = 80ml. This unusual fraction appears in recipes that scale for 2 servings from a 3-serving base. It cannot be made from combining standard 1/4 and 1/8 cup measures without error.
One-third cup is common in yogurt parfait recipes, small-batch granola bars, and single-layer cake recipes scaled for 2 servings. It is exactly 80ml in metric volume.
