1 Cup Brown Sugar in Millilitres
1 cup of brown sugar is 236.6 ml and weighs 213 g (packed, King Arthur Baking). White sugar coated in molasses; light and dark differ only in molasses content. 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.
Every sugar on this site is measured the same way in volume — one US cup is 236.6 ml — yet the weight in that cup swings widely from one sweetener to the next. A fine powder packs tightly, a coarse crystal leaves air gaps, and a syrup is denser than any dry sugar. This page gives you both figures so you can follow a recipe however it is written.
Why millilitres and grams are two different answers
The reason this page lists two numbers for every amount is that a cup is a unit of volume, not of weight. One US cup holds 236.6 ml of anything, but what that space weighs depends on what fills it. Granulated sugar, brown sugar and powdered sugar all occupy the same 236.6 ml, yet their weights differ by up to 100 g per cup. Packing changes the answer further: a packed cup of brown sugar weighs far more than a loosely filled one. That is why serious bakers weigh sweeteners. The millilitre column tells you what to pour into a jug; the gram column tells you what to put on a scale. Use the one that matches your recipe, and when the recipe matters, use grams.

| 4 cups | 946.4 ml | 852 g | 64 tbsp |
The table covers the amounts recipes actually ask for, from a quarter cup up to four cups. One tablespoon of brown sugar is about 13.3 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 213 g per cup, measured packed. 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 brown sugar?
| Millilitres | Cups | Grams |
|---|---|---|
| 100 ml | 0.4 cups | 90 g |
| 250 ml | 1.1 cups | 225.1 g |
| 500 ml | 2.1 cups | 450.1 g |
Recipes written in metric units often call for round millilitre amounts rather than cups, so this table bridges the two. 250 ml of brown sugar is just over a cup — 1.1 cups — and weighs 225.1 g, while 500 ml is 2.1 cups and 450.1 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
Cookies calling for 2 cups of brown sugar
A cookies recipe that calls for 2 cups of brown sugar needs 473.2 ml, which weighs 426 g. That is the figure to measure: pour 473.2 ml into a liquid jug, or weigh 426 g straight into the bowl. Because brown sugar is used for cookies, barbecue sauces, glazes and oatmeal. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 426 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Barbecue sauces calling for half a cup of brown sugar
A barbecue sauces recipe that calls for half a cup of brown sugar needs 118.3 ml, which weighs 106.5 g. That is the figure to measure: pour 118.3 ml into a liquid jug, or weigh 106.5 g straight into the bowl. Because brown sugar is used for cookies, barbecue sauces, glazes and oatmeal. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 106.5 g removes the guesswork entirely, and it is the only way to repeat the recipe exactly next time.
Glazes calling for 3 cups of brown sugar
A glazes recipe that calls for 3 cups of brown sugar needs 709.8 ml, which weighs 639 g. That is the figure to measure: pour 709.8 ml into a liquid jug, or weigh 639 g straight into the bowl. Because brown sugar is used for cookies, barbecue sauces, glazes and oatmeal. the amount matters — too little and the result is flat or bland, too much and the balance of the dish tips. Weighing 639 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 1278 g. Halve it and you need 354.9 ml, or 319.5 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 225.1 g of brown sugar, not 213 g. Check which cup your recipe uses before you convert.
How the weight was measured
Packed means the ingredient is pressed firmly into the measuring cup until it holds the shape of the cup when turned out. This is the standard way to measure this ingredient, and it matters a great deal: loosely spooned, the same cup can weigh tens of grams less.
The source for the 213 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. Packed firmly, per King Arthur; loosely spooned brown sugar weighs about 170 g per cup, so packing matters more than brand. This page follows the King Arthur Baking value of 213 g per cup, measured packed, rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Common mistakes with brown 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 with a clay disc or bread slice to stop it hardening. White sugar coated in molasses; light and dark differ only in molasses content. Keeping brown 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. brown sugar is used for cookies, barbecue sauces, glazes and oatmeal. and it is worth keeping a note of the 213 g per cup figure on the container, so the conversion is always to hand.
Frequently asked questions
How many grams is 1 cup of brown sugar?
1 cup of brown sugar weighs 213 g, measured packed 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 brown 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 brown sugar without a scale?
Packed means the ingredient is pressed firmly into the measuring cup until it holds the shape of the cup when turned out. This is the standard way to measure this ingredient, and it matters a great deal: loosely spooned, the same cup can weigh tens of grams less. That gives the closest result to 213 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 brown sugar weigh the same as water?
No. One cup of brown sugar weighs 213 g, which is lighter than water, which weighs 237 g per cup — 24 g lighter. That is why you cannot convert brown sugar by assuming a millilitre weighs a gram: for water the shortcut works, but for brown sugar it would be off by 24 g per cup, and the error grows with the size of the recipe.
How many cups is 250 ml of brown sugar?
250 ml of brown sugar is 1.1 cups, and it weighs 225.1 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 brown sugar on a kitchen scale.
