One millilitre of packed brown sugar is 0.92988562 grams, so converting millilitres of packed brown sugar to grams means multiplying by 0.92988562. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Water is the yardstick: 1 mL of it weighs 1 g. Packed brown sugar comes in at 0.92989 g per mL, or 92.99% of water, which is why a cup of it is 220 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
Packed brown sugar has a density of 0.92989 g per mL, so 100 mL of it weighs 92.99 g and 250 mL weighs 232.5 g. That single figure is what every other number on this page is built from — water is 1.00 g per mL, so this ingredient is 92.99% as heavy as the same volume of water.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.455% of a cup of packed brown sugar, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.273 cups, and a 1 kg pack 4.545.
What the number depends on: Firmly packed, which is the US recipe convention. Spooned in loosely it is closer to 145 g per cup.
The formula
millilitres- The amount of packed brown sugar you are converting, in millilitres
0.929885624301- Grams per millilitre for packed brown sugar, from its density of 0.92989 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in millilitres.
- It is multiplied by 0.929885624301, the grams-per-millilitre figure for packed brown sugar.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
15 mL of packed brown sugar in grams
Take 15 mL of packed brown sugar: 15 × 0.92988562 gives 13.9483 grams. Doubling the batch takes it to 27.8966 grams, because the relationship is a straight proportion once the density is known.
100 mL of packed brown sugar in grams
Take 100 mL of packed brown sugar: 100 × 0.92988562 gives 92.9886 grams. Doubling the batch takes it to 185.977 grams, because the relationship is a straight proportion once the density is known.
250 mL of packed brown sugar in grams
Take 250 mL of packed brown sugar: 250 × 0.92988562 gives 232.471 grams. Doubling the batch takes it to 464.943 grams, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many grams are in 1 mL of packed brown sugar?
One millilitre of packed brown sugar is 0.92988562 grams. Half that quantity is 0.464943 grams and double it is 1.85977 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of packed brown sugar not 236 g like water?
Because weight per cup depends on what is in the cup. Packed brown sugar has a density of 0.92989 g per mL where water has 1.00, so a cup of it weighs 220 g rather than 236.6 g. That is a difference of 16.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of packed brown sugar by roughly 20% — about 22 g either side of 220 g — because firmly packed, which is the US recipe convention. Weighing removes the question entirely.
Is a fluid ounce of packed brown sugar the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of packed brown sugar weighs 0.97 oz, so the two readings differ by 3%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of packed brown sugar would weigh 232.47 g instead of 220 g — 12.5 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
At this size the spoon wins. One millilitre of packed brown sugar is 0.9299 g, and a scale reading to the nearest gram is working at 108% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How many millilitres of packed brown sugar is 500 g?
500 g of packed brown sugar is 537.7 millilitres — 1.0754 millilitres to one gram, so 500 × 1.0754 = 537.7. Going that way is a division by 0.929886, or a multiplication by 1.0754 if you prefer.
