Cups to Ounces Granulated Sugar Cooking Size Chart
This chart converts granulated sugar between cups and ounces, covering 10 measurements from cups 1/8 up to cups 3. Because granulated sugar has a specific density that differs from other ingredients, these conversions apply only to granulated sugar — do not use them for other ingredients.
In baking and cooking, precision matters. A recipe calling for cups 1/8 of granulated sugar needs exactly ounces 0.9 — using a conversion for a different ingredient could throw off the balance of your recipe. Our chart accounts for the actual weight-to-volume ratio of granulated sugar.

How to Measure Your Ingredients Size
For dry ingredients, spoon the ingredient into the measuring cup and level off with a straight edge — never scoop directly from the bag, as this packs the ingredient and adds up to 20% extra weight. For liquids, use a liquid measuring cup (with a pour spout) and read at eye level on a flat surface. A digital kitchen scale is the most accurate option and eliminates the need for volume conversions altogether.
Tips for Converting Granulated Sugar Cooking Sizes
Weight-based measurements (grams, ounces) are more accurate than volume measurements (cups, tablespoons) for baking. Professional bakers almost always weigh ingredients.
Humidity, packing density, and grain size all affect how much of a dry ingredient fits in a cup. Two people measuring '1 cup of flour' can end up with weights differing by 30 grams.
When a recipe gives both weight and volume, always prefer the weight measurement — it is what the recipe developer used.

Frequently Asked Questions
- How do I convert granulated sugar from cups to ounces?
- Use our granulated sugar conversion chart above. For example, cups 3/4 of granulated sugar equals ounces 5.3. The chart covers 10 measurements so you can find the exact conversion you need.
- Does granulated sugar weigh the same as other ingredients per cup?
- No. Each ingredient has a different density, so 1 cup of granulated sugar weighs a different amount than 1 cup of flour, sugar, or any other ingredient. That is why ingredient-specific conversion charts like this one exist — using a generic converter will give inaccurate results.
- Should I measure granulated sugar by weight or volume?
- Weight (grams or ounces) is more accurate for baking because volume measurements like cups can vary by up to 20% depending on how the ingredient is scooped and packed. If your recipe gives both, always prefer the weight measurement. A digital kitchen scale is the most reliable tool.
- What is the smallest granulated sugar conversion in this chart?
- The smallest measurement in our chart is cups 1/8 of granulated sugar, which equals ounces 0.9.
- What is the largest granulated sugar conversion available?
- The largest measurement covered is cups 3 of granulated sugar, which converts to ounces 21.2. If you need a larger quantity, multiply the appropriate row from our chart.
- How do I measure granulated sugar accurately for baking?
- For cups, use the spoon-and-level method: spoon granulated sugar into the measuring cup, then sweep a straight edge across the top to level it off. Never scoop directly from the container — this packs the ingredient and gives you more than the recipe intended. For grams or ounces, use a digital scale set to zero (tared) with your bowl on it.
- Can I use this chart for granulated sugar in savoury recipes too?
- Yes. The weight-to-volume ratio of granulated sugar is the same regardless of whether you are baking or cooking a savoury dish. These conversions apply to any recipe that calls for granulated sugar.
