⚡ Quick answer
There is no single grams-to-cups conversion — it depends on the ingredient. 1 cup of all-purpose flour = 125g. 1 cup of sugar = 200g. 1 cup of butter = 227g.
Cups measure volume, grams measure weight. Since every ingredient has a different density, the gram weight of one cup varies dramatically. A cup of honey weighs 340g; a cup of rolled oats weighs just 90g. The full chart below covers every common baking ingredient — use it to convert in both directions.
The grams-to-cups question is one of the most Googled baking queries for a simple reason: American recipes use cups, the rest of the world uses grams, and neither side is going to stop any time soon. If you’re baking from a US recipe with a European kitchen scale — or vice versa — you need a reliable reference table that actually covers the ingredients you’re using.
The critical thing to understand before using any grams-to-cups chart is that the conversion is ingredient-specific, not universal. There is no “1 cup = Xg” rule that works across ingredients the way “1 inch = 2.54cm” works for length. A cup of all-purpose flour weighs 125g because flour is a light, airy powder. A cup of honey weighs 340g because honey is a dense liquid. Using a generic “1 cup = 240g” shortcut — which some sources suggest — will produce wildly wrong results for most dry ingredients.
The numbers in the charts below are based on the most widely accepted baking standards: all-purpose flour and other dry ingredients use the spoon-and-level method (spoon ingredient into the cup measure, level with a straight edge). For packed ingredients like brown sugar, values assume a firmly packed cup. For liquids, values are based on water density at room temperature. Where different sources give slightly different values, this chart uses the average of the most cited professional baking references.

Every professional baker and patisserie chef in the world uses grams. This isn’t snobbery — it’s physics. Measuring by weight removes the single biggest source of variation in home baking: the way different people fill a cup.
Research consistently shows that when home bakers measure flour by volume, a “cup” can weigh anywhere from 110g to 175g depending on technique. Scooping the measuring cup directly into a flour bag compresses the flour and gives you 140–160g. Sifting into the cup and then levelling gives you 110–115g. Spooning and levelling — the standard method — gives 120–130g. That’s a 50% variation for what the recipe calls “1 cup.” When flour is your largest ingredient, that variance directly determines texture.
Weighing eliminates all of this. 125g of flour is always 125g, regardless of whether you scoop, spoon, sift, or pour it. For recipes that are easy to nail — a simple banana bread or chocolate chip cookies — the method difference is forgiving. For technically demanding bakes like croissants, macarons, chiffon cake, or sourdough, the difference between 125g and 155g of flour is the difference between success and a failed bake.
❌ Cup measuring (scooping)
1 cup flour — anywhere from 110g to 175g
Direct scooping compacts the flour. Overfilling, under-levelling, and humidity all add variation. A 50% weight range for the same “1 cup” measurement is common across different bakers.
✅ Gram measuring (scale)
125g flour — exactly 125g every time
A kitchen scale costing £10–20 removes all measuring variation instantly. Weighing is also faster for multiple ingredients — tare the scale between each ingredient and measure directly into the bowl.

How to Convert Grams to Cups Without a Chart
For ingredients not covered in the table above, you can find the conversion yourself with one measurement and simple division. The method works for any ingredient with a known cup weight.
1
Find the weight of 1 cup for your ingredient
Look up the ingredient in a trusted source — the USDA FoodData Central database, a professional baking reference, or a reputable food brand’s website. You need the weight per cup using the standard spoon-and-level method. For liquids, use the density (grams per ml) multiplied by 240ml.
2
Divide your gram amount by the weight per cup
Formula: Cups = Grams ÷ Grams-per-cup. Example: you have 375g of all-purpose flour and the recipe uses cups. 375 ÷ 125 = 3 cups. For a fraction: 250g sugar ÷ 200g-per-cup = 1.25 cups = 1¼ cups.
3
Convert the decimal to a cup fraction
0.25 cups = ¼ cup · 0.33 cups = ⅓ cup · 0.5 cups = ½ cup · 0.67 cups = ⅔ cup · 0.75 cups = ¾ cup. If your result is something like 1.4 cups, express it as 1 cup + 6½ tablespoons (since 0.4 × 16 tablespoons ≈ 6.4 tablespoons).
4
For odd fractions, switch to tablespoons or a scale
If your conversion lands on something awkward — 1.3 cups or ⅝ cup — you have two clean options: measure in tablespoons (1 cup = 16 tablespoons, so 1.3 cups = 20 tablespoons + 2½ teaspoons), or just weigh the ingredient in grams directly. The gram weight is always exact; the cup fraction is always an approximation.
💡
The tare method saves time when scaling recipes: If you’re baking from a gram recipe and want to measure in cups, use the conversion table to find the weight for each ingredient, then weigh directly into your mixing bowl. Set the bowl on the scale, tare to zero, add the first ingredient to its weight, tare again, add the second — faster than swapping between cup measures and washing them between ingredients.
Flour Conversions in Detail — The Most Common Source of Error
Flour is the ingredient where grams-to-cups conversion errors cause the most damage, and it’s where the most confusion exists about what “1 cup” actually means. Different flour types also have meaningfully different cup weights — not just flour vs flour, but the same type measured by different techniques.

Scooped values are approximate — actual weight depends on how firmly the cup is pressed into the bag. All standard values based on spoon-and-level technique. Always use spoon-and-level unless the recipe specifies otherwise.
⚠️
Scooping flour is the single most common cause of dense, dry baked goods: Most home bakers who complain that a recipe “didn’t work” were scooping their flour — adding 20–35g more than the recipe intended per cup. If a recipe calls for 2 cups of flour and you scoop both, you may be adding 60–70g of extra flour. That’s half a cup. Spoon and level every time, or weigh.
Key Takeaways
There is no universal grams-to-cups conversion — every ingredient has a different weight per cup based on its density.
1 cup all-purpose flour = 125g · 1 cup granulated sugar = 200g · 1 cup butter = 227g · 1 cup water = 240g.
Scooping flour directly from the bag adds 25–35g per cup over the spoon-and-level standard — always spoon and level dry ingredients.
Brown sugar values assume a firmly packed cup — loosely filled brown sugar weighs significantly less.
Honey weighs 340g per cup — nearly three times as much as oats (90g per cup) — density variation is extreme across ingredients.
Grams are more accurate than cups for baking: a kitchen scale removes all measuring variation and is faster for multi-ingredient recipes.
To convert any gram amount: divide by the ingredient’s weight per cup. 250g sugar ÷ 200g = 1.25 cups = 1¼ cups.
One cup of all-purpose flour weighs 125 grams using the spoon-and-level method — spoon the flour into the measuring cup without packing it, then sweep a straight edge across the top to level. If you scoop the measuring cup directly from the flour bag, the cup will typically weigh 150–160g because the action compresses the flour. Most American recipes are written to the 125g standard, so the spoon-and-level technique is always correct unless the recipe specifies otherwise. In tablespoons, 125g is 1 cup or 16 tablespoons.
How many grams in a cup of sugar?
One cup of granulated white sugar weighs 200 grams. This is a much denser ingredient than flour — sugar crystals pack tightly, leaving very little air space between them. Brown sugar is denser still when packed: one cup of firmly packed brown sugar weighs approximately 220 grams. Powdered (icing) sugar is lighter: one cup weighs about 120 grams, closer to flour, because the fine particles trap more air. The type of sugar matters significantly when converting — always check which sugar the recipe specifies.
How many grams in a cup of butter?
One cup of butter weighs 227 grams (half a pound). In US baking, butter is often sold in 113g (¼ lb) sticks marked with tablespoon and cup measurements on the wrapper — one cup is two standard sticks. Half a cup of butter is 113g; a quarter cup is 57g. These are among the easiest baking conversions to memorise because butter packaging usually shows them directly. For European butter sold in 250g blocks, one cup equals approximately 90% of the block.
Is 1 cup always 240ml regardless of the ingredient?
In terms of volume, yes — a US cup is always 240ml regardless of what you put in it. But the weight of that 240ml of space varies completely based on what’s filling it. 240ml of water = 240g. 240ml of honey = 340g. 240ml of all-purpose flour = 125g. 240ml of rolled oats = 90g. This is the core principle: cups measure volume (space), grams measure mass (weight). The same volume of space holds very different weights depending on ingredient density. So while the cup is a fixed volume unit, the gram equivalent is always ingredient-specific.
How many grams in a cup of oats?
One cup of rolled oats (old-fashioned oats) weighs 90 grams. This is because oats are large, irregular flakes that leave substantial air gaps in the cup — making them one of the lightest-per-cup dry baking ingredients. Quick oats (more finely cut) pack slightly denser at around 95–100g per cup. Steel-cut oats are denser still at roughly 160–170g per cup because they’re small, dense pellets with minimal air space. Always check which type of oat your recipe specifies, as they’re not interchangeable by volume or weight.
Why do different websites give different gram values for the same ingredient?
The variation comes from three sources: measuring technique (spoon-and-level vs scooped vs sifted), cup size (US 240ml vs UK/Australian 250ml), and ingredient brand or grind (different flour mills have slightly different particle sizes that affect packing density). Most professional sources and food science references use the spoon-and-level method with a 240ml US cup — this is the standard this chart uses. When you see a different value on another site, it’s almost always because they used a different technique or cup size. If you’re following a specific recipe, use the values from that recipe’s source country.
How do I convert a recipe from cups to grams for the whole recipe at once?
Work through each ingredient individually using the conversion chart — there’s no shortcut that applies a single factor to every ingredient at once. For a full recipe, the fastest approach is to use SavoryTribe’s Ingredient Unit Converter, which handles each ingredient’s specific density automatically. For manual conversion: identify each ingredient, find its cup weight from this chart, multiply by the number of cups in the recipe. Example: 2½ cups of all-purpose flour = 2.5 × 125g = 313g. Write down each gram value and you have a weight-based recipe you can reuse accurately every time.
How many grams in half a cup of flour?
Half a cup of all-purpose flour weighs 63 grams (half of 125g). For other flours: ½ cup bread flour = 65g · ½ cup cake flour = 50g · ½ cup whole wheat flour = 60g · ½ cup almond flour = 56g. These are all based on the spoon-and-level standard. Half-cup measurements come up frequently when halving a recipe that originally calls for 1 cup — in that case, weighing 63g directly on a scale is more accurate than trying to fill a ½ cup measure to the precise halfway point.
