Cups of granulated sugar to ounces runs on one number, 7.0547924 ounces per cup. It is a measured property of this ingredient rather than a defined conversion, which is why a generic volume-to-weight tool cannot give you it.
Put next to water — 1 g per mL exactly — granulated sugar measures 0.84535 g per mL. That ratio, 84.54%, is what separates this page from every other ingredient in the same units, and it is measured rather than defined.
A cup of granulated sugar is 200 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 180 g and 240 g covers the range from lightly spooned to firmly packed. That 20% spread is larger than most of the adjustments recipes fuss over, and it disappears entirely the moment the ingredient is weighed instead.
One cup of granulated sugar is 7.055 oz. US kitchen scales usually step in eighths of an ounce, which is 3.54 g — around 1.77% of a cup of this ingredient, so the scale is precise enough for a full cup and coarse for a spoonful. That is why recipes mix the two systems: ounces for the bulk, spoons for the small amounts.
How the figure is arrived at: One of the most reliable ingredients to measure by volume: the crystals are uniform and do not compact under their own weight.
The formula
cups- The amount of granulated sugar you are converting, in cups
7.05479238992- Ounces per cup for granulated sugar, from its density of 0.84535 g/mL
ounces- The equivalent quantity in ounces
How it works, step by step
- Enter the quantity in cups.
- It is multiplied by 7.05479238992, the ounces-per-cup figure for granulated sugar.
- The result appears in ounces, with a second reading in g beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
1/3 cup of granulated sugar in ounces
A recipe calling for 1/3 cup of granulated sugar needs 2.3516 ounces on the scale. The arithmetic is 0.333333 × 7.0547924 = 2.3515975, and halving the recipe halves the weight to 1.1758 ounces.
3/4 cup of granulated sugar in ounces
3/4 cup of granulated sugar weighs out at 5.29109 ounces. Divide 5.29109 by 7.0547924 and you get back to 3/4 cup, which is the quickest check that the factor is the right way up.
3 cup of granulated sugar in ounces
A recipe calling for 3 cup of granulated sugar needs 21.1644 ounces on the scale. The arithmetic is 3 × 7.0547924 = 21.164377, and halving the recipe halves the weight to 10.5822 ounces.

Frequently asked questions
How many ounces are in 1 cup of granulated sugar?
One cup of granulated sugar is 7.0547924 ounces. Half that quantity is 3.5274 ounces and double it is 14.1096 ounces, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of granulated sugar not 236 g like water?
Because weight per cup depends on what is in the cup. Granulated sugar has a density of 0.84535 g per mL where water has 1.00, so a cup of it weighs 200 g rather than 236.6 g. That is a difference of 36.6 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 granulated sugar by roughly 20% — about 20 g either side of 200 g — because one of the most reliable ingredients to measure by volume: the crystals are uniform and do not compact under their own weight. Weighing removes the question entirely.
Is a fluid ounce of granulated 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 granulated sugar weighs 0.8818 oz, so the two readings differ by 11.8%. 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 granulated sugar would weigh 211.34 g instead of 200 g — 11.3 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?
A scale, if the result matters. Volume measuring carries a spread of about 20% for granulated sugar — roughly 40 g on a 200 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How many cups of granulated sugar is 16 oz?
16 oz of granulated sugar is 2.268 cups — 0.141748 cups to one ounce, so 16 × 0.141748 = 2.268. Going that way is a division by 7.05479, or a multiplication by 0.141748 if you prefer.
