1 Cup Cinnamon in Millilitres
1 cup of cinnamon is 236.6 ml and weighs 125 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.
A cup of ground spice is 236.6 ml, but the weight of that cup depends on how fine the grind is and how densely the powder settles. Two spices that look alike in the jar can differ by 50 g per cup. The table below gives you millilitres and grams together, with the method and source, so even a large batch can be scaled accurately.
Why millilitres and grams are two different answers
Volume and weight are different questions, and ground spices prove it. One US cup is 236.6 ml, and every spice fills it — but the weight ranges from about 86 g to about 288 g per cup across the spice drawer. Grind size, moisture and how settled the jar is all move the number. A cup measure is also a poor tool for spices in practice: a whole cup is far more than any recipe needs, so the table's smaller rows — a quarter cup, a third — are the ones you will actually use, and the gram column is the accurate way to scale them.
Cinnamon cups to millilitres conversion table
| Cups | Millilitres | Grams | Tablespoons |
|---|---|---|---|
| 1/4 cup | 59.1 ml | 31.2 g | 4 tbsp |
| 1/3 cup | 78.9 ml | 41.7 g | 5.3 tbsp |
| 1/2 cup | 118.3 ml | 62.5 g | 8 tbsp |
| 2/3 cup | 157.7 ml | 83.3 g | 10.7 tbsp |
| 3/4 cup | 177.4 ml | 93.8 g | 12 tbsp |
| 1 cup | 236.6 ml | 125 g | 16 tbsp |
| 2 cups | 473.2 ml | 250 g | 32 tbsp |
| 3 cups | 709.8 ml | 375 g | 48 tbsp |
| 4 cups | 946.4 ml | 500 g | 64 tbsp |
The table covers the amounts recipes actually ask for, from a quarter cup up to four cups. One tablespoon of cinnamon is about 7.8 g and 14.8 ml, which is handy when a recipe calls for a spoonful rather than a cup: divide the cup weight by 16 and you have the tablespoon weight. Remember that the millilitre column never changes — 1 cup is always 236.6 ml — while the gram column depends on the USDA density of 125 g per cup, measured spooned and levelled. If your recipe was written in grams, read the gram column; if it was written in cups or millilitres, read the millilitre column.
How much is 100 ml, 250 ml and 500 ml of cinnamon?
| Millilitres | Cups | Grams |
|---|---|---|
| 100 ml | 0.4 cups | 52.8 g |
| 250 ml | 1.1 cups | 132.1 g |
| 500 ml | 2.1 cups | 264.2 g |
Recipes written in metric units often call for round millilitre amounts rather than cups, so this table bridges the two. 250 ml of cinnamon is just over a cup — 1.1 cups — and weighs 132.1 g, while 500 ml is 2.1 cups and 264.2 g. A standard measuring jug usually has both millilitre and cup markings, so you can pour to either scale, but the gram column is the one to use on a scale. Note that 100 ml is 0.4 of a cup, which is why metric recipes rarely line up neatly with cup measures.
Worked examples
Baking calling for 2 cups of cinnamon
A baking recipe that calls for 2 cups of cinnamon needs 473.2 ml, which weighs 250 g. That is the figure to measure: pour 473.2 ml into a liquid jug, or weigh 250 g straight into the bowl. Because cinnamon is used for baking, oatmeal, curries and drinks. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 250 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Oatmeal calling for half a cup of cinnamon
A oatmeal recipe that calls for half a cup of cinnamon needs 118.3 ml, which weighs 62.5 g. That is the figure to measure: pour 118.3 ml into a liquid jug, or weigh 62.5 g straight into the bowl. Because cinnamon is used for baking, oatmeal, curries and drinks. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 62.5 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Curries calling for 3 cups of cinnamon
A curries recipe that calls for 3 cups of cinnamon needs 709.8 ml, which weighs 375 g. That is the figure to measure: pour 709.8 ml into a liquid jug, or weigh 375 g straight into the bowl. Because cinnamon is used for baking, oatmeal, curries and drinks. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 375 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Scaling works the same way in both directions. Double the recipe and 3 cups becomes 1419.6 ml, or 750 g. Halve it and you need 354.9 ml, or 187.5 g. When you scale, always scale by weight if the original recipe was written in grams, and by volume if it was written in cups — mixing the two mid-recipe is how scaling errors creep in. And remember that a US cup is 236.6 ml, while a metric cup is 250 ml: if you are following a recipe from Australia, New Zealand or South Africa, one cup means 250 ml, which is 132.1 g of cinnamon, not 125 g. Check which cup your recipe uses before you convert.
How the weight was measured
Spooned and levelled means the ingredient is spooned loosely into the measuring cup and the top is swept flat with a straight knife. The ingredient is never scooped with the cup itself and never pressed down, because both of those habits pack extra material into the cup and push the weight up.
The source for the 125 g 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.
The figure is not disputed in the same way as the flour and sugar conversions: USDA lists 125 g per cup, and other reliable sources cluster close to it. Small differences of a gram or two between sources are rounding, not disagreement.
Common mistakes with cinnamon
- Scooping the spice out of the jar. Dipping the cup into the jar packs the powder. Spoon it in and level it off, or the weight creeps up with every scoop.
- Measuring over a steaming pot. Steam clumps ground spices and adds moisture weight. Measure away from the heat, then add the spice to the pot.
- Swapping one spice's weight for another. A cup of salt weighs more than three times a cup of ground ginger. Never use one spice's conversion for a different spice.
- Trusting an old, settled jar. A jar that has sat for months settles denser at the bottom. Stir or shake it before measuring, or weigh the spice.
Storage and handling
Airtight jar, cool and dark, up to 1 year. Warm, sweet spice ground from cinnamon bark. 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 a sealed container 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. cinnamon is used for baking, oatmeal, curries and drinks. and it is worth keeping a note of the 125 g per cup figure on the container, so the conversion is always to hand.
Frequently asked questions
How many grams is 1 cup of cinnamon?
1 cup of cinnamon weighs 125 g, measured spooned and levelled according to USDA. That is the figure the conversion table on this page is built on, and it is the value to use when a recipe gives weights. All the gram figures here are approximate, so when a bake really matters, verify with a kitchen scale.
Is 1 cup of cinnamon always 236.6 ml?
Yes, as long as the recipe means a US customary cup. One US cup is 236.6 ml by definition, whatever is in it. The confusion comes from the metric cup, which is 250 ml, and from the old imperial cup. If a recipe does not say which cup it uses, a US recipe almost always means the 236.6 ml cup, while a recipe from Australia or New Zealand usually means the 250 ml metric cup.
How do I measure cinnamon without a scale?
Spooned and levelled means the ingredient is spooned loosely into the measuring cup and the top is swept flat with a straight knife. The ingredient is never scooped with the cup itself and never pressed down, because both of those habits pack extra material into the cup and push the weight up. That gives the closest result to 125 g per 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 cinnamon weigh the same as water?
No. One cup of cinnamon weighs 125 g, which is lighter than water, which weighs 237 g per cup — 112 g lighter. That is why you cannot convert cinnamon by assuming a millilitre weighs a gram: for water the shortcut works, but for cinnamon it would be off by 112 g per cup, and the error grows with the size of the recipe.
How many cups is 250 ml of cinnamon?
250 ml of cinnamon is 1.1 cups, and it weighs 132.1 g. The table above lists 100 ml, 250 ml and 500 ml alongside their cup equivalents, so a recipe written in millilitres converts in one step. For anything more precise, weigh the cinnamon on a kitchen scale.
