3/4 cup of granulated sugar weighs about 148.5 g. That is the short answer, measured spooned and levelled and taken from King Arthur Baking — and the rest of this guide explains exactly how that number was worked out, where it can go wrong, and how to use it in real recipes.
3/4 cup of granulated sugar in grams
| Amount | Grams (approx.) |
|---|---|
| 1/8 cup | 24.8 g |
| 1/4 cup | 49.5 g |
| 1/3 cup | 66 g |
| 1/2 cup | 99 g |
| 2/3 cup | 132 g |
| 3/4 cup | 148.5 g ← this page |
| 1 cup | 198 g |
| 1 1/2 cups | 297 g |
| 2 cups | 396 g |
All figures are approximate. One US cup of granulated sugar weighs 198 g spooned and levelled (King Arthur Baking), and every fraction above is calculated from that figure. When the result matters — a cake, a loaf, a sauce you cannot remake — verify with a kitchen scale.
Why 3/4 cup of granulated sugar is a tricky amount to measure
A 3/4 cup measure is small enough that a single careless scoop changes the result by a large percentage. With a full cup, a 10 g error is a small share of the total; with 3/4 cup, the same 10 g error is a much bigger share of what you are adding. That is why weighing matters more, not less, for small amounts. Granulated Sugar is Refined white cane or beet sugar; the default sugar in most recipes. The practical consequence is simple: if you scoop granulated sugar straight from the bag with your measuring cup, you can easily add 15–20% more than the recipe intends, and in baking that is the difference between a tender crumb and a dry one, or between a sauce that thickens and one that stays thin.
Worked examples
Example 1: halving a recipe that calls for 1 1/2 cup
A recipe written for a full batch asks for 1 1/2 cup of granulated sugar. You want half as much, which is 3/4 cup. On the scale that is 148.5 g. Weigh it once, and the rest of the recipe halves cleanly — no mental arithmetic with measuring cups, and no second batch of a dry ingredient you cannot take back once it is in the bowl.
Example 2: measuring granulated sugar for baking
Baking often needs a modest amount of granulated sugar, and 3/4 cup is a typical quantity. Weighing 148.5 g straight into the pan or bowl avoids dirtying a measuring cup and keeps the amount exact. If you are cooking by feel, remember that granulated sugar is refined white cane or beet sugar; the default sugar in most recipes. so the weight, not the volume, is what the recipe writer was counting on.
Example 3: baking with a recipe from another country
Many recipes from the US list granulated sugar in cups while the rest of your kitchen works in grams. Converting 3/4 cup to 148.5 g lets you follow the recipe without converting every other ingredient back to cups. Keep the conversion table below bookmarked: the same 198 g-per-cup figure gives you every fraction from 1/8 cup to two cups.
How 3/4 cup of granulated sugar is measured
The figure of 148.5 g is based on granulated sugar measured spooned and levelled, following King Arthur Baking. One full cup weighs 198 g under that method, and 3/4 cup is simply that figure multiplied by 0.75.
King Arthur lists 198 g per cup; USDA FoodData Central rounds granulated sugar to 200 g per cup. The 2 g difference is rounding, not a real disagreement. That is why the headline number is labelled approximate: it is a calculation from a published full-cup density, not a measurement of the exact spoonful in your kitchen.
If your granulated sugar was measured differently, the weight changes. A scooped cup packs more in; a sifted cup holds less; a packed cup of a sticky ingredient holds far more than a spooned one. The method matters as much as the number, which is why every conversion on this site states its method alongside its source. When a recipe matters — a celebration cake, a loaf of bread you have been planning, a sauce you cannot remake — weigh the granulated sugar on a kitchen scale and let the scale settle the argument. 148.5 g is a good target; the scale tells you when you have actually hit it.
King Arthur Baking is the source for the full-cup figure, and this site uses that value consistently across every granulated sugar page, so the quarter-cup, half-cup and full-cup figures all agree with each other. If you have seen a different number elsewhere, it almost certainly comes from a different method or a different source's rounding — not from a different ingredient.
Practical guidance for granulated sugar
Sweetening drinks, baking, preserving and candy-making. Sweetness is the obvious role, but granulated sugar also affects moisture, browning and texture. 3/4 cup at 148.5 g is a small dose, yet in a small batch it can be the difference between a balanced bake and one that is cloyingly sweet or oddly pale.
Storage changes the number too. Airtight container, cool and dry, indefinitely. Sugar that has absorbed moisture clumps and packs more densely, so a cup weighed on a humid day can be heavier than the same cup in dry conditions. Keep it sealed and break up clumps before measuring.
The most common failure with granulated sugar is oversweetening by volume. Because granulated sugar is measured spooned and levelled, a careless scoop adds grams fast. If a recipe tastes too sweet, weigh the 148.5 g next time before changing anything else — the recipe is usually right and the measure is usually the problem.
Common mistakes with 3/4 cup of granulated sugar
Scooping the cup straight from the bag or jar. This packs granulated sugar down and can add 15–20% extra weight. Spoon it in loosely and level it off, or better, weigh it.
Using a liquid measuring jug for a dry ingredient (or the reverse). Dry cups and liquid jugs are not interchangeable, and the meniscus on a jug makes small dry amounts hard to read.
Forgetting to tare the scale. Weighing the bowl as well as the granulated sugar adds its weight to your reading, so always press tare with the empty bowl on the scale first.
If you do not have a scale
Use a 3/4 cup measure if you have one. Fill it using the spooned and levelled method: spoon granulated sugar in, do not press it down, and level the top with the back of a knife.
Four level tablespoons are roughly 3/4 cup of a cup — about 148.5 g of granulated sugar. Tablespoons are easier to level accurately than a small cup, so this is a decent fallback.
If you only have a 1-cup measure, fill it to the 3/4 cup line and level it. Read it at eye level on a flat surface; reading from above makes the line look lower than it is.
Remember that any of these fallbacks is approximate. A kitchen scale is inexpensive, and it turns every conversion on this site — including this 148.5 g figure — from a good guess into a measurement you can trust.
Frequently asked questions
How many grams is 3/4 cup of granulated sugar?
3/4 cup of granulated sugar is about 148.5 g, measured spooned and levelled and based on King Arthur Baking's figure of 198 g per cup. The figure is approximate — granulated sugar varies with brand, grind and humidity — so verify with a kitchen scale when the recipe matters.
Is 148.5 g exact for 3/4 cup of granulated sugar?
No. 148.5 g is an approximate figure calculated from King Arthur Baking's full-cup value of 198 g. granulated sugar does not have a single fixed density: King Arthur lists 198 g per cup; USDA FoodData Central rounds granulated sugar to 200 g per cup. The 2 g difference is rounding, not a real disagreement. A kitchen scale gives you the true weight of what you actually added, which is why weighing beats converting.
Can I use 3/4 cup of granulated sugar in place of a full cup in a recipe?
Only if you are scaling the whole recipe down. 3/4 cup is a quarter of a cup, so replacing a full cup with 3/4 cup quarters the amount of granulated sugar and will change the recipe's structure, moisture or sweetness. If you want a smaller batch, scale every ingredient by the same factor.
Does the weight of 3/4 cup of granulated sugar change if it is cold or warm?
Barely, for most purposes. Temperature changes the density of granulated sugar only slightly, and 148.5 g stays a good working figure. The bigger variables are how it was measured and how it was stored — humidity and packing change the weight far more than temperature does.
How much is 3/4 cup of granulated sugar in ounces?
3/4 cup of granulated sugar is about 5.2 oz by weight (since one ounce is 28.35 g). Ounces on a recipe usually mean weight, so this is the figure to use on a scale that reads in ounces.
