1/2 Cup Cinnamon in Grams
1/2 cup of cinnamon weighs 62.5 g (spooned and levelled, USDA). Warm, sweet spice ground from cinnamon bark. All the figures on this page are approximate conversions based on the USDA value, so when a recipe really matters, verify with a kitchen scale.
Warm, sweet spice ground from cinnamon bark. It is used for baking, oatmeal, curries and drinks. That range of uses is part of why the conversion comes up so often: the same ingredient appears in everyday cooking and in precise baking, and the two situations demand different levels of accuracy. Knowing the weight of half a cup, rather than guessing from a measuring cup, keeps the result consistent no matter which recipe you are following.
Why weighing half a cup of cinnamon beats measuring it in cups
Half a cup is a large amount for a spice, and it usually appears in recipes that are being made in bulk: a big batch of curry paste, a rub for a whole brisket, a jar of pickling spice or a large pot of chilli. cinnamon is potent, so the difference between a level half-cup and a heaped one is not a subtle change in flavour, it is a different dish. The 62.5 g figure on this page is the standard for cinnamon measured spooned and levelled from USDA, so it gives you a fixed number to work from whether you are cooking for four or for forty. Once you know the weight, scaling a recipe up or down becomes simple arithmetic instead of a gamble.
Cinnamon cups to grams conversion table
| Cups | Grams (approx.) |
|---|---|
| 1/4 cup | 31.5 g |
| 1/3 cup | 41.5 g |
| 1/2 cup | 62.5 g |
| 2/3 cup | 83.5 g |
| 3/4 cup | 94 g |
| 1 cup | 125 g |
| 1 1/2 cups | 187.5 g |
| 2 cups | 250 g |
| 3 cups | 375 g |
One tablespoon of cinnamon weighs about 8 g, and one teaspoon about 2.5 g. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one. The table is rounded to the nearest half gram, so the numbers are approximate by design; the half-cup figure of 62.5 g is the one to use when a recipe calls for half a cup.
How the weight was measured
Spooned and levelled means spooning the ingredient into the measuring cup until it is heaped, then sweeping a straight knife across the top to level it off. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight.
The source for the 125 g per cup figure is USDA, and the confidence in the value is medium. USDA publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Because cinnamon is measured spooned and levelled, the weight per cup is stable from one kitchen to the next, and the 62.5 g figure for half a cup is a reliable default. Small differences in brand or temperature shift it by only a gram or two, which is far below the threshold that changes a recipe.
All the figures on this page are approximate conversions. When a recipe really matters, verify with a kitchen scale: weigh the ingredient directly into the bowl on a tared scale and trust that number over any cup.
Worked examples
A curry paste for the freezer
A curry paste using 1/2 cup of cinnamon needs 62.5 g, and the spice must be weighed precisely because it is the backbone of the flavour. Too little and the paste is bland; too much and it is bitter. Weigh it once, freeze the paste in portions, and every future curry will taste the same.
Scaling up a pickling spice mix
A pickling mix that starts with 2 cups of cinnamon needs 250 g. At that scale a cup-measure error compounds badly, and an over-spiced pickle is hard to rescue, so weighing the full amount on a scale is the only sensible approach.
A seasoning blend for the week
A seasoning blend calling for 1/3 cup of cinnamon needs about 41.5 g. The spice balances salt and heat in the blend, and weighing it keeps the balance right even when you scale the recipe for a crowd.
When this conversion matters most
The weight matters whenever cinnamon is doing the heavy lifting on flavour. In a curry the spice is the dish; in a cake it is the character; in a rub it is the crust. In a single serving, by contrast, a gram or two either way is invisible, so save the scale for the recipes where the spice is load-bearing and season freely where it is not.
Common mistakes with cinnamon
- Using a tablespoon for a half-cup. Eight tablespoons of a fine powder means eight chances to pack it differently. Weigh 62.5 g in one go instead.
- Rounding down to save time. Rounding 62.5 g to a neat number feels tidy but is a real error when the ingredient is potent. Keep the real figure; the scale does the work for you.
- Swapping spices by volume. Different spices weigh different amounts per cup, so swapping cinnamon for another spice cup-for-cup changes the recipe. Swap by weight instead.
- Storing spices above the stove. Heat and steam degrade spices and change how they pack. Keep cinnamon in a cool, dark cupboard as the storage note advises.
Storage and handling
Airtight jar, cool and dark, up to 1 year. Keeping cinnamon stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so good storage is not just about freshness, it is about measurement accuracy too. If a container has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup.
Frequently asked questions
How many grams is 1/2 cup of cinnamon?
1/2 cup of cinnamon weighs 62.5 g, measured spooned and levelled according to USDA. That is the figure to use when converting a recipe from cups to grams, and it is the value the conversion table on this page is built on.
How do I measure cinnamon without a scale?
Spooned and levelled means spooning the ingredient into the measuring cup until it is heaped, then sweeping a straight knife across the top to level it off. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight. That gives the closest result to 62.5 g per half-cup, but it is still an estimate: the honest answer is that a scale is the only way to know the exact weight, and a basic digital kitchen scale costs less than a bag of good flour.
Does 1/2 cup of cinnamon always weigh 62.5 g?
No. Brand, grind, moisture and how settled the jar is all shift the weight by a few grams. The 62.5 g figure is the standard USDA value for cinnamon measured spooned and levelled, and it is the right default, but when a recipe is precise, weigh the ingredient and trust the scale over the cup.
What is cinnamon used for?
Baking, oatmeal, curries and drinks. Warm, sweet spice ground from cinnamon bark.
Why is 1/2 cup of cinnamon so much lighter than 1/2 cup of sugar?
Because cinnamon is a fine, airy powder while sugar is a dense crystal. Volume measures how much space something takes up, not how much of it there is, which is exactly why weighing in grams is more reliable than measuring in cups.
How should I store cinnamon?
Airtight jar, cool and dark, up to 1 year. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
