Grams to Cups Converter – Convert g to Cups by Ingredient
Converting grams to cups depends entirely on the ingredient you are measuring. Unlike a straight unit conversion, grams measure mass while cups measure volume. So 100 grams of flour fills a different cup amount than 100 grams of sugar, butter, or rice. Use the grams to cups converter above to select your ingredient and get an instant result.
This page covers a full grams to cups conversion chart and dedicated sections for 100 g and 200 g conversions. It also includes cup fractions in grams and ingredient-specific guides for flour, sugar, and butter. You can also convert grams to cups for oats, honey, rice, cocoa, and more using the tables below.
How to Convert Grams to Cups
To convert grams to cups, divide the ingredient weight in grams by the ingredient density (grams per cup). Each ingredient packs differently into a cup, so there is no single conversion factor.
Formula: Cups = Grams divided by (Ingredient density in g per cup)
For example, all-purpose flour has a density of about 125 g per cup using the spoon-and-level method. So 250 grams of flour equals 250 divided by 125, which is 2 cups. For white granulated sugar at 200 g per cup, 250 grams equals 250 divided by 200, which is 1.25 cups.
The fastest approach is to use the grams to cups converter above. The grams to cups conversion chart below covers the most common ingredients.

How Many Cups Is 100 Grams?
The answer to how many cups is 100 grams depends on the ingredient. Here are the most common 100-gram conversions:
- 100 grams of flour = 0.80 cups (about three-quarters of a cup plus 1 tablespoon)
- 100 grams of sugar = 0.50 cups (half a cup exactly)
- 100 grams of butter = 0.44 cups (just under half a cup)
- 100 grams of oats = 1.11 cups (about 1 cup plus 1 tablespoon)
- 100 grams of honey = 0.29 cups (about a quarter cup plus 1 tablespoon)
- 100 grams of rice = 0.53 cups (just over half a cup)
- 100 grams of cocoa powder = 0.83 cups (about three-quarters of a cup)
200 Grams to Cups by Ingredient
200 grams to cups is one of the most searched recipe conversion questions. Knowing how many cups is 200 grams for common ingredients saves time when scaling or adjusting recipes. Here are the exact values:
- 200 grams of flour = 1.60 cups
- 200 grams of sugar = 1.00 cup (exactly 1 cup of white granulated sugar)
- 200 grams of butter = 0.88 cups
- 200 grams of oats = 2.22 cups
- 200 grams of honey = 0.59 cups
- 200 grams of rice = 1.05 cups
- 200 grams of water or milk = 0.85 cups
Note that 200 grams of white sugar equals exactly 1 cup. This makes sugar one of the easiest ingredients to measure by either weight or volume.
Cup Fractions to Grams: 1/4 Cup, 1/3 Cup, 1/2 Cup, and More
Many recipes use cup fractions. The table below covers common cup amounts in grams for the most-used baking ingredients. This includes the commonly searched 1 1/4 cup grams and 1 1/3 cup in grams values.
| Cup amount | Flour (g) | Sugar (g) | Butter (g) | Oats (g) |
|---|---|---|---|---|
| 1/4 cup (0.25 cup) | 31 g | 50 g | 57 g | 23 g |
| 1/3 cup (0.33 cup) | 42 g | 67 g | 76 g | 30 g |
| 1/2 cup (0.5 cup) | 63 g | 100 g | 114 g | 45 g |
| 2/3 cup (0.67 cup) | 83 g | 133 g | 152 g | 60 g |
| 3/4 cup (0.75 cup) | 94 g | 150 g | 170 g | 68 g |
| 1 cup | 125 g | 200 g | 227 g | 90 g |
| 1 1/4 cups | 156 g | 250 g | 284 g | 113 g |
| 1 1/3 cups | 167 g | 267 g | 303 g | 120 g |
| 1 1/2 cups | 188 g | 300 g | 341 g | 135 g |
| 2 cups | 250 g | 400 g | 454 g | 180 g |
To convert cups to grams, simply read the table from right to left or use the calculator above. For tablespoon measurements, see DigiCalc's grams to tablespoons converter.
Grams to Cups for Flour
Flour is the ingredient where measurement accuracy matters most. Grams to cups flour values vary by flour type:
- All-purpose flour: 125 g per cup (spoon-and-level method)
- Bread flour: 127 g per cup
- Whole wheat flour: 120 g per cup
- Cake flour: 100 g per cup (much lighter, typically sifted)
- Almond flour: 96 g per cup
The 1 1/2 cup flour in grams for all-purpose flour is 188 g. When a recipe calls for 1 1/2 cups of flour, weighing 188 grams on a kitchen scale gives the most consistent result. Scooping flour directly from a bag can add 20 to 30 extra grams per cup due to compaction. This may cause baked goods to be too dense or dry.
The National Institute of Standards and Technology (NIST) confirms that mass measurement removes variability. Compressible dry ingredients like flour are especially prone to inconsistency when measured by volume.
Grams to Cups for Sugar
Sugar types have noticeably different densities. Here are the exact grams to cups sugar values for common sugar types:
- White granulated sugar: 200 g per cup
- Brown sugar (packed): 220 g per cup
- Powdered or icing sugar: 120 g per cup
- Caster or superfine sugar: 200 g per cup
- Raw or turbinado sugar: 180 g per cup
Powdered sugar weighs significantly less per cup because it is more aerated. A recipe calling for 1 cup of powdered sugar uses only 120 g, while 1 cup of brown sugar uses 220 g. Always check which sugar type the recipe specifies before using the grams to cups converter.
Grams to Cups for Butter
Butter conversions are used in both baking and cooking. The standard grams to cups butter ratio is 227 g per cup, based on one standard US cup (236.6 mL). Common butter conversions:
- 1 1/2 cup butter in grams = 341 g
- 1 cup butter = 227 g
- 1/2 cup butter = 113.5 g (one US stick)
- 1/4 cup butter = 57 g
- 1 tablespoon butter = 14.2 g
Butter is typically sold in 250 g or 500 g blocks in most countries, and in 113.5 g sticks in the United States. Whether you are measuring cold block butter or soft butter at room temperature, the weight-to-volume ratio remains the same. The grams to cups calculator handles both directions automatically.
US Cup vs Metric Cup
Not all cups are the same size. The difference between a US cup and a metric cup matters when following international recipes:
- US customary cup: 236.6 mL
- Metric cup (Australia, Canada, New Zealand): 250 mL
- Imperial cup (old UK standard): 284 mL (now largely replaced by metric)
The metric cup holds about 6% more volume than the US cup. For a recipe calling for 2 cups of flour, that is 250 g using a US cup vs 265 g using a metric cup. For everyday cooking this difference is small, but in baking it can affect the outcome. Most online recipes published globally use the US cup standard unless the author specifies otherwise.
The grams to cups converter on this page uses the US cup (236.6 mL). If your recipe uses metric cups, multiply the cup result by 0.946 to get the correct metric cup amount.
Grams to Cups and Tablespoons
For small ingredient quantities, converting grams to cups and tablespoons gives more practical measurements. One US tablespoon equals 14.8 mL, and there are 16 tablespoons in 1 cup. Common small-quantity conversions:
- 25 g flour = about 3 tablespoons plus 1 teaspoon
- 25 g white sugar = 2 tablespoons
- 25 g butter = 1 tablespoon plus 2 teaspoons
- 15 g flour = about 2 tablespoons
- 10 g sugar = 2.5 teaspoons
- 10 g butter = about 2 teaspoons
Measuring Cups in Grams: When a Scale Is Better
The concept of measuring cups in grams is common in baking communities, and is central to accurate cooking measurements. Converting between volume and mass is a volume conversion that requires knowing each ingredient's density. Volume measurements introduce two main sources of error:
- Compaction: Scooping a measuring cup directly into flour can add 20 to 40 extra grams compared to the spoon-and-level method. This is a difference of up to 25%, enough to make baked goods noticeably denser or drier.
- Leveling technique: Without leveling the cup with a straight edge, volume measurements vary by 10 to 15% between different people using the same recipe.
For casual everyday cooking, cup measurements are convenient and usually accurate enough. For baking, using grams on a kitchen scale gives consistent results every time. Professional bakers use grams almost exclusively. A basic kitchen scale costs very little and removes all guesswork from ingredient measurement.
Limitations of Grams to Cups Conversion
- Ingredient-specific: There is no universal grams-to-cups ratio. Every ingredient has a different density.
- Processing matters: Sifted flour weighs less per cup than unsifted. Packed brown sugar weighs more than loosely measured brown sugar.
- Cup standards vary: Always confirm whether a recipe uses US cups (236.6 mL) or metric cups (250 mL).
- Temperature effects: Very cold butter packs differently into a cup than room-temperature butter, affecting volume measurements.
- Irregular ingredients: For coarse ingredients such as nuts, chocolate chips, or dried fruit, gram weights are far more reliable than cup volumes.
