There are about 2.1 cups in a pound of brown sugar. A pound is 453.59 g, and one cup of brown sugar weighs 213 g when measured packed, so 453.59 divided by 213 gives 2.1 cups. The figure is approximate: cup weights vary with how the cup is filled, how settled the ingredient is, and the brand you buy, so if the recipe matters, weigh the brown sugar on a kitchen scale instead of counting cups. For everyday cooking, 2.1 cups per pound is the number to use.

White sugar coated in molasses; light and dark differ only in molasses content. Cookies, barbecue sauces, glazes and oatmeal. That is why the cup count for brown sugar is different from the cup count for other ingredients: a pound of flour fills nearly four cups, while a pound of honey fills fewer than one and a half, because a cup of honey weighs 336 g and a cup of brown sugar weighs 213 g. Weight is the same for every ingredient — a pound is always 453.59 g — but volume is not, and the cup count per pound is simply the pound divided by the weight of one cup.

Pounds to cups conversion table

The table below converts pounds of brown sugar to cups, using 213 g per cup (packed). Every figure is approximate, and the gram column is exact — a pound is 453.59 g whatever you are weighing.

Weight Cups (approx.) Grams
0.25 lb 0.5 cups 113.4 g
0.5 lb 1.1 cups 226.79 g
0.75 lb 1.6 cups 340.19 g
1 lb 2.1 cups 453.59 g
1.5 lb 3.2 cups 680.38 g
2 lb 4.3 cups 907.18 g
3 lb 6.4 cups 1360.77 g
4 lb 8.5 cups 1814.36 g
5 lb 10.6 cups 2267.95 g
10 lb 21.3 cups 4535.9 g

For the amounts most recipes use, the useful rows are the small ones: a quarter pound is 0.5 cups, half a pound is 1.1 cups, and three quarters of a pound is 1.6 cups. If your recipe is written in pounds and your measuring tools are cups, read the cups column; if your recipe is written in cups and you buy by the pound, read it the other way — a recipe that needs 2 cups takes 0.9 lb, and a recipe that needs 3 cups takes 1.4 lb.

Cups to grams and ounces

The table below works in the other direction: cups of brown sugar to grams and ounces. One cup is 213 g, which is 7.5 oz, and every other row is a multiple of that.

Cups Grams (approx.) Ounces (approx.)
1/4 cup 53.25 g 1.9 oz
1/3 cup 71 g 2.5 oz
1/2 cup 106.5 g 3.8 oz
2/3 cup 142 g 5 oz
3/4 cup 159.75 g 5.6 oz
1 cup 213 g 7.5 oz
2 cups 426 g 15 oz
3 cups 639 g 22.5 oz
4 cups 852 g 30.1 oz

These are the figures to write on a recipe card. A recipe that calls for 1/2 cup needs 106.5 g, a recipe that calls for 2 cups needs 426 g, and a recipe that calls for 4 cups needs 852 g. Weighing removes the cup entirely: put the bowl on the scale, tare it, and pour until the display reads the gram figure. It is faster than measuring cups, it uses one less tool to wash, and it is the same every time, whatever brand of brown sugar you bought.

Worked examples

A barbecue rub for the weekend

A barbecue rub for two racks of ribs uses about 1/2 cup of brown sugar, which is 106.5 g — 0.2 lb, a small share of a pound bag. That is the point of knowing the pound conversion for a savoury recipe: a pound of brown sugar is 2.1 cups, so a rub recipe barely dents the bag, and the rest keeps for months in a sealed jar. Mix the rub in a bowl, rub it over the meat, and let it sit for at least an hour so the sugar draws out moisture and forms a crust. If the rub is for a pork shoulder, double the sugar to 1 cup (213 g) — the extra sugar caramelises over a long, slow cook and gives the bark its colour.

Granola for the week

A weekly batch of granola uses 1/2 cup of brown sugar to coat the oats, which is 106.5 g. A pound holds 2.1 cups, so one bag covers 4.26 batches of granola — roughly 4 weeks if you make a batch every Sunday. Weigh the sugar rather than measuring it in a cup, because granola depends on the sugar coating the oats evenly: too much and the granola clumps into a single hard sheet; too little and it stays loose and dry. Pour the weighed sugar over the oats with the oil, toss until every flake is coated, and bake low and slow, stirring halfway through.

Doubling a brownie recipe

A brownie recipe for one pan uses 1 cup of brown sugar — 213 g. Doubled for a bake sale, that is 2 cups or 426 g, which is 0.9 lb. A pound bag holds 2.1 cups, so the doubled recipe takes almost the whole bag. Brownies are forgiving about sugar within a small range, but weighing still matters: sugar is what keeps brownies moist and chewy, and under-measuring by a quarter cup makes them drier and more cake-like. Weigh 426 g, melt it with the butter and chocolate, and the texture will be the same as the single batch, just twice as much of it.

How the figure is worked out

The calculation is a single division. A pound is defined as 453.59 g. One cup of brown sugar weighs 213 g, measured packed from a US cup of 236.6 ml, according to King Arthur Baking. Divide the pound by the cup weight — 453.59 divided by 213 — and the answer is 2.1 cups. There is no other step, and no other number involved, which is why the figure is easy to check: if you know the grams per cup, you know the cups per pound.

The cup weight itself is where the uncertainty lives. One cup of brown sugar weighs 213 g, measured packed from a US cup of 236.6 ml. The figure comes from King Arthur Baking and carries high confidence in our table. A cup is a volume, not a weight, so anything that changes how much of the ingredient fits in that volume changes the weight: how firmly it is packed and how much moisture it has absorbed That is why this page labels every result approximate and why a scale is the only way to be certain.

There is a dispute note on this figure worth knowing. Packed firmly, per King Arthur; loosely spooned brown sugar weighs about 170 g per cup, so packing matters more than brand. That is why every result on this page is labelled approximate, and why a kitchen scale is the only way to be certain when a recipe has to come out exactly right.

The spoon measures follow from the same cup weight. A cup holds 16 tablespoons, so one tablespoon of brown sugar weighs 13.3 g, and one teaspoon weighs 4.4 g. The small table below gives the figures you will actually use when a recipe calls for spoonfuls rather than cups.

Measure Grams (approx.)
1 teaspoon 4.4 g
1 tablespoon 13.3 g
2 tablespoons 26.6 g
1/4 cup 53.2 g
1/2 cup 106.5 g
1 cup 213 g

Practical guidance

White sugar coated in molasses; light and dark differ only in molasses content. Cookies, barbecue sauces, glazes and oatmeal. Airtight container with a clay disc or bread slice to stop it hardening.

The most common mistake with brown sugar is measuring it the wrong way for its form. Sugar is measured packed, and the method is the whole story: a loosely filled cup can be far lighter than the 213 g figure, so two bakers measuring the same recipe in cups can end up with different amounts of sugar. For brown sugar, pack it firmly into the cup, pressing it down with the back of a spoon, and level the top — loosely spooned, it weighs far less per cup. Store it in an airtight container in a cool, dry place, and if it hardens into a lump, a slice of bread in the jar overnight softens it again.

If you do not have a scale, the cup figures on this page will get you close enough for everyday cooking, but not for precision baking. A basic digital kitchen scale costs little, weighs in grams, and removes the single biggest source of variation in baking. Until you have one, spoon and level dry ingredients, use a liquid jug for liquids, and never scoop from the bag.

Frequently asked questions

How many cups are in a pound of brown sugar?

About 2.1 cups. A pound is 453.59 g, and one cup of brown sugar weighs 213 g, so 453.59 divided by 213 is 2.1. The figure is approximate, because the cup weight depends on how the cup is filled — packed firmly gives 213 g, while a loosely spooned cup weighs far less.

How many grams are in a pound of brown sugar?

453.59 g. A pound is always 453.59 g whatever the ingredient is; what changes is how many cups that weight fills. For brown sugar, 453.59 g fills about 2.1 cups.

Is a pound of brown sugar the same as 2 cups?

Yes, almost exactly — a pound of brown sugar is 2.1 cups, so 2 cups is a very good approximation. Measuring by weight avoids the error entirely.

Should I pack brown sugar into the cup?

Yes — brown sugar is measured packed, so press it firmly into the cup and level the top. Loosely spooned, it weighs far less per cup, and your recipe will come out short on sugar. The 213 g per cup figure assumes the packed method.

Does the cup count change if the sugar is lumpy or damp?

Yes. Lumps and moisture both change how much sugar fits in a cup, which is why the 2.1 cups per pound figure is approximate. Break up lumps before measuring, and store the sugar in an airtight container so it stays dry. If the sugar has hardened into a solid block, soften it with a slice of bread in the sealed jar overnight rather than chipping pieces off and measuring those.

How many tablespoons are in a pound of brown sugar?

About 34.07 tablespoons. A pound is 2.1 cups, and there are 16 tablespoons in a cup, so 2.1 times 16 is 34.07. That is 102.22 teaspoons. Spoon measures are useful for small amounts, but for a whole pound, weighing is faster and more accurate.
