1 Cup Granulated Sugar in Millilitres
1 cup of granulated sugar is 236.6 ml and weighs 198 g (spooned and levelled, King Arthur Baking). Refined white cane or beet sugar; the default sugar in most recipes. All the figures on this page are approximate conversions based on the King Arthur Baking value, so when a recipe really matters, verify with a kitchen scale.
Sweeteners are where cup measurements cause the most trouble, because a cup of one sugar can weigh almost twice as much as a cup of another. The volume is always the same — 236.6 ml — but the weight depends entirely on crystal size, moisture and how the cup was filled. That is why this page gives you both numbers: the millilitres for your jug and the grams for your scale.
Why millilitres and grams are two different answers
Millilitres measure space and grams measure mass, and for sugar the two drift apart because crystals do not pack the same way. A cup of fine caster sugar settles with very little air between the grains, while a cup of coarse demerara leaves gaps. Syrups are denser still, because there is no air in them at all. So the millilitre figure — 236.6 ml per cup — is a property of the cup, while the gram figure is a property of the sugar. Confusing the two is how a cake ends up too sweet or too dry: the recipe asked for a weight and the cook supplied a volume, or the other way round. Keep the two columns of the table separate in your mind, and use the millilitre column when your recipe speaks in cups and the gram column when it speaks in grams.
Granulated Sugar cups to millilitres conversion table
| Cups | Millilitres | Grams | Tablespoons |
|---|---|---|---|
| 1/4 cup | 59.1 ml | 49.5 g | 4 tbsp |
| 1/3 cup | 78.9 ml | 66 g | 5.3 tbsp |
| 1/2 cup | 118.3 ml | 99 g | 8 tbsp |
| 2/3 cup | 157.7 ml | 132 g | 10.7 tbsp |
| 3/4 cup | 177.4 ml | 148.5 g | 12 tbsp |
| 1 cup | 236.6 ml | 198 g | 16 tbsp |
| 2 cups | 473.2 ml | 396 g | 32 tbsp |
| 3 cups | 709.8 ml | 594 g | 48 tbsp |
| 4 cups | 946.4 ml | 792 g | 64 tbsp |
The table covers the amounts recipes actually ask for, from a quarter cup up to four cups. One tablespoon of granulated sugar is about 12.4 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 King Arthur Baking density of 198 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 granulated sugar?
| Millilitres | Cups | Grams |
|---|---|---|
| 100 ml | 0.4 cups | 83.7 g |
| 250 ml | 1.1 cups | 209.2 g |
| 500 ml | 2.1 cups | 418.4 g |
Recipes written in metric units often call for round millilitre amounts rather than cups, so this table bridges the two. 250 ml of granulated sugar is just over a cup — 1.1 cups — and weighs 209.2 g, while 500 ml is 2.1 cups and 418.4 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
Sweetening drinks calling for 2 cups of granulated sugar
A sweetening drinks recipe that calls for 2 cups of granulated sugar needs 473.2 ml, which weighs 396 g. That is the figure to measure: pour 473.2 ml into a liquid jug, or weigh 396 g straight into the bowl. Because granulated sugar is used for sweetening drinks, baking, preserving and candy-making. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 396 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Baking calling for half a cup of granulated sugar
A baking recipe that calls for half a cup of granulated sugar needs 118.3 ml, which weighs 99 g. That is the figure to measure: pour 118.3 ml into a liquid jug, or weigh 99 g straight into the bowl. Because granulated sugar is used for sweetening drinks, baking, preserving and candy-making. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 99 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Preserving calling for 3 cups of granulated sugar
A preserving recipe that calls for 3 cups of granulated sugar needs 709.8 ml, which weighs 594 g. That is the figure to measure: pour 709.8 ml into a liquid jug, or weigh 594 g straight into the bowl. Because granulated sugar is used for sweetening drinks, baking, preserving and candy-making. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 594 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 1188 g. Halve it and you need 354.9 ml, or 297 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 209.2 g of granulated sugar, not 198 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 198 g figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking 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.
There is a dispute worth knowing about. King Arthur lists 198 g per cup; USDA FoodData Central rounds granulated sugar to 200 g per cup. The 2 g difference is rounding, not a real disagreement. This page follows the King Arthur Baking value of 198 g per cup, measured spooned and levelled, rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Common mistakes with granulated sugar
- Scooping instead of spooning. Dipping the cup into the bag packs the sugar and adds grams the recipe did not ask for. Spoon it in and level it off.
- Packing a sugar that should be spooned. Only brown sugar and muscovado are measured packed. Packing granulated or caster sugar over-measures it by a wide margin.
- Measuring syrups in a dry cup. Sticky syrups cling to a dry cup and never fully reach the bowl. Use a liquid jug, or weigh the syrup straight into the bowl.
- Swapping sugars cup for cup. A cup of honey weighs nearly 70 percent more than a cup of granulated sugar. Swap by weight, and adjust the liquid in the recipe, or the bake will be too wet and too sweet.
Storage and handling
Airtight container, cool and dry, indefinitely. Refined white cane or beet sugar; the default sugar in most recipes. Keeping granulated sugar 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. granulated sugar is used for sweetening drinks, baking, preserving and candy-making. and it is worth keeping a note of the 198 g per cup figure on the container, so the conversion is always to hand.
Frequently asked questions
How many millilitres is 1 cup of granulated sugar?
1 cup of granulated sugar is 236.6 ml. That is the fixed volume of one US customary cup, and it is the same for every ingredient on this site: the cup does not change, only the weight inside it does. If your recipe is from a metric country, note that a metric cup is 250 ml, which is a different measure — check which cup the recipe means before converting.
How many grams is 1 cup of granulated sugar?
1 cup of granulated sugar weighs 198 g, measured spooned and levelled according to King Arthur Baking. 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 granulated sugar 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 granulated sugar 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 198 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 granulated sugar weigh the same as water?
No. One cup of granulated sugar weighs 198 g, which is lighter than water, which weighs 237 g per cup — 39 g lighter. That is why you cannot convert granulated sugar by assuming a millilitre weighs a gram: for water the shortcut works, but for granulated sugar it would be off by 39 g per cup, and the error grows with the size of the recipe.
