180 g of turbinado sugar is 1 cup (approximately, spooned and levelled, King Arthur Baking). That is the answer this page is built around: one cup of turbinado sugar weighs 180 g, so 180 ÷ 180 = 1 cup. Coarse, golden raw sugar with a light molasses flavour. It is used for topping muffins, sweetening coffee and crunchy cookie coatings. This page is for the cook who has a scale in one hand and a recipe in grams in the other, and wants to know what that weight looks like in cups. You will find the full grams-to-cups table, three worked examples, and the method notes behind the number.
Conversion table: grams of turbinado sugar to cups
The table below runs from 25 g to 500 g. Every figure is grams ÷ 180 g per cup, rounded to a sensible cup measure, and every figure is approximate. The 180 g row is this page's headline amount — exactly one cup — and the rows around it cover the weights you will meet when a recipe is halved, doubled, or written for a different batch size.
| Grams | Cups (approx.) |
|---|---|
| 25 g | 1/7 cup |
| 50 g | 2/7 cup |
| 75 g | 3/7 cup |
| 100 g | 4/7 cup |
| 150 g | 5/6 cup |
| 180 g | 1 cup |
| 200 g | 1 1/8 cups |
| 250 g | 1 2/5 cups |
| 300 g | 1 2/3 cups |
| 400 g | 2 1/5 cups |
| 500 g | 2 4/5 cups |
A useful check on the table: one tablespoon of turbinado sugar weighs about 11.2 g, because there are 16 tablespoons in a cup and 180 ÷ 16 = 11.2. That helps when the weight you need falls between two table rows — measure the cups, then make up the difference in spoonfuls. It also shows why converting through tablespoons alone is a poor plan for a whole cup: sixteen small measures carry sixteen small errors, while one weighing carries one.
Worked examples: 180 g of turbinado sugar in real recipes
Example 1 — a European recipe in grams
A recipe from a scale-first kitchen lists 180 g of turbinado sugar and you cook with cups. Divide by the grams per cup: 180 ÷ 180 = 1 cup. Measure one cup, spooned and levelled, and you have matched the recipe exactly. This is the most common use of this page, and it is also the most forgiving one — because the conversion is exact at this weight, there is no rounding to worry about, only the method.
Example 2 — doubling to 360 g
Double the recipe and the weight doubles to 360 g, which is 2 cups (360 ÷ 180). Weigh it if you can — at two cups, the packing error of scooping doubles too — but if you are measuring in cups, two level cups, spooned and levelled, will get you there. Remember that doubling the recipe also doubles the tin size and roughly adds a quarter to the baking time.
Example 3 — halving to 90 g
Halve the recipe and you need 90 g, which is 1/2 cup (90 ÷ 180). A half cup is easy to measure accurately, which makes halving by cups more reliable than doubling by cups — the errors are smaller because the amount is smaller. Weigh it if the recipe is fussy; a half cup measured carefully is a good second choice.
How the cup was measured (and why it matters)
Every figure on this page assumes the cup was spooned and levelled. That phrase is doing real work: for turbinado sugar, the difference between a spooned cup and a scooped cup can be 10 to 20 percent, which is far more than any rounding in the table. To measure spooned and levelled, use a dry measuring cup (not a liquid jug), fill it without packing unless the method says packed, and level it off with the back of a knife. For poured ingredients, use a liquid measuring jug at eye level. The source for the 180 g per cup figure is King Arthur Baking, and the confidence in the figure is high. There is no famous dispute about the weight of turbinado sugar: the figure used here is stable across the sources we checked, which is one reason this conversion is reliable. Even so, every figure on this page is labelled approximate, because how full the cup is, how settled the ingredient is, and the temperature in your kitchen all move the number a little. When precision matters, verify with a kitchen scale.
When the conversion matters most
The conversion matters most where turbinado sugar does structural work. In baking, too much of a dry ingredient makes a crumb dry and dense, while too little makes it collapse; too much of a wet one makes a batter slack and slow to set. For topping muffins, sweetening coffee and crunchy cookie coatings. the stakes are real but not mysterious: convert carefully, follow the recipe's order, and check the batter's look before it goes in the oven. Storage matters too: Airtight container, cool and dry, indefinitely.
Scaling the recipe up or down
One cup (180 g) is rarely the only amount a recipe needs, so here is how the number scales. A half batch needs 90 g, which is 1/2 cup. A quarter batch needs 45 g, which is 1/4 cup. A double batch needs 360 g, which is 2 cups. And a triple batch needs 540 g, which is 3 cups. The pattern is the same every time — divide the grams by 180 to get cups — but the practicalities change with size. Small batches are forgiving: a few grams either way will not show. Large batches are not: a small error in one cup becomes a large error across three, and the tin, the mixing bowl and the baking time all have to grow with it. A triple batch needs a bowl with real headroom, a tin (or two tins) with roughly three times the volume, and a bake that you check early, because the outside browns before the middle sets. Scale the raising agents and the salt by the same factor as everything else — the commonest scaling mistake is scaling the bulk ingredients and forgetting the small ones. Weigh each scaled amount rather than converting in your head, and write the scaled numbers down before you start: a recipe scaled on paper is a recipe you can repeat, while a recipe scaled from memory is a recipe you will have to guess at again next time.
Frequently asked questions
How many cups is 180 g of turbinado sugar?
180 g of turbinado sugar is 1 cup (approximately). One cup weighs 180 g (spooned and levelled, King Arthur Baking), so the calculation is 180 ÷ 180. The figure is approximate, so verify with a kitchen scale when precision matters.
How many grams is 1 cup of turbinado sugar?
One cup of turbinado sugar weighs 180 g, spooned and levelled, according to King Arthur Baking. That is the anchor figure for every conversion on this page: divide any gram weight by 180 to get cups, or multiply any cup amount by 180 to get grams.
Can I measure 180 g of turbinado sugar without a scale?
Yes — measure one cup with a dry measuring cup, spooning the turbinado sugar in loosely and levelling it off with a straight edge. Do not scoop with the cup and do not pack it unless the method says packed. A careful cup lands close to 180 g, which is good enough for everyday cooking, though a scale is better for baking.
Why do different websites give different weights for turbinado sugar?
Because they measure the cup differently. King Arthur Baking lists 180 g per cup spooned and levelled, while other sources may scoop, sift or pack, and each method gives a different weight. The ingredient itself has not changed — only the measuring method has. Match the method and the numbers agree.
Is it better to weigh turbinado sugar or measure it in cups?
Weighing is better whenever the recipe is a bake or a batch you want to repeat, because a scale reads the same every time while a cup varies with how you fill it. For soups, sauces and weekday cooking, a careful cup measure is usually fine. The threshold is the recipe: if the result depends on the ratio, weigh it.
What if my recipe calls for 250 g of turbinado sugar?
250 g is 1 2/5 cups (250 ÷ 180). Measure one cup and add about 70 g more, or weigh 250 g directly — which is easier and more accurate. The table on this page covers 25 g to 500 g for exactly these in-between weights.
