Grams to Cups Converter (g to cups)

How to Convert Grams to Cups

Grams (g) measure weight. US cups measure volume. Since different ingredients have different densities, the same weight of two ingredients fills different amounts of a measuring cup. For instance, 100 grams of flour takes up far more space than 100 grams of sugar or butter — which is why you can't just use a single "universal" multiplier.

The easiest way to convert grams to cups is to use the calculator above or one of the reference tables below. For manual calculation, the formula is:

Cup Subdivisions — Quick Reference

US recipes often use fractions of cups. Here's how they convert to other volume units — useful when you need to measure grams to teaspoons or tablespoons to grams:

Measurement	Cups	Tablespoons	Teaspoons	Milliliters
1 cup	1	16	48	236.59 mL
3/4 cup	0.75	12	36	177.44 mL
2/3 cup	0.667	10⅔	32	157.73 mL
1/2 cup	0.5	8	24	118.29 mL
1/3 cup	0.333	5⅓	16	78.86 mL
1/4 cup	0.25	4	12	59.15 mL
1/8 cup	0.125	2	6	29.57 mL

US Cup vs. Metric Cup vs. Japanese Cup

Not every "cup" is the same. If you're following an Australian, British, or Japanese recipe, the cup size differs from the US standard. The FDA defines a separate "legal cup" for nutrition labels.^[3]

Cup Standard	Volume (mL)	Used In	200g Flour =
US customary cup	236.588 mL	American recipes (this calculator)	1.59 cups
US legal cup	240 mL	US nutrition labels	1.57 cups
Metric cup	250 mL	Australia, NZ, Canada	1.51 cups
Japanese cup	200 mL	Japanese cooking	1.89 cups
Imperial cup	284.131 mL	Historical British (rarely used)	1.33 cups

This matters: the same recipe calling for "2 cups of flour" means 250g in an American kitchen, but 265g in an Australian kitchen. Always check which cup standard your recipe uses — or better yet, weigh in grams.

When to Convert Grams to Cups

Grams and cups are both commonly used to measure cooking ingredients. For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.^[2] The density of dry ingredients can vary for a variety of reasons, such as compaction and clumping.

• Following metric recipes with US measuring tools: European, Australian, and professional baking recipes specify ingredients in grams. If you only own a set of measuring cups and spoons, you need to convert grams to cups.
• Scaling baking recipes: A recipe might call for "2 cups of flour," but if you're halving or doubling it, calculating in grams first (then converting back to cups) prevents rounding errors. Use our recipe scale calculator for automatic scaling.
• Comparing nutritional information: US nutrition labels specify serving sizes in grams, but your mental reference might be in cups. Knowing that a 30g serving of cereal ≈ about 1 cup helps you visualize portion sizes.^[5]
• Meal planning and portioning: When you have a 500g bag of flour and need to know how many cups that gives you (about 4 cups), gram-to-cup conversion helps plan how many batches of cake or pizza dough you can make.
• Converting between volume units: If you need to convert milliliters to grams or grams to milliliters, the same density-based formula applies.

Common Mistakes When Converting Grams to Cups

• "1 cup = 240g for everything" — This only works for water. 1 cup of flour is about 125g, and 1 cup of honey is about 336g. The weight per cup varies wildly by ingredient.
• Using the wrong cup size — If an Australian recipe says "1 cup," they mean 250 mL (metric cup), not 236.59 mL (US cup). That's a 5.7% difference, which matters in precision baking.
• Not accounting for how you scoop — A "cup of flour" can weigh 120g (spooned and leveled) or 150g (scooped and packed). Professional recipes in grams eliminate this ambiguity entirely.^[4]
• Confusing weight ounces and fluid ounces — 1 cup = 8 fluid ounces (volume). But 1 cup of flour weighs about 4.4 ounces (weight). These are completely different measurements. Our ounces to grams converter helps clarify this.

What Is a Gram?

A gram (g) is a metric unit of mass equal to 1/1,000 of a kilogram, or 0.035274 ounces. It is equivalent to the mass of one cubic centimeter (one milliliter) of water at 4°C. The gram is an SI unit of mass in the metric system and can be abbreviated as g — for example, 1 gram can be written as 1 g.

While technically a gram measures mass (not weight), the two are equivalent for everyday calculations performed on Earth. A gram is frequently referred to as a unit of weight in cooking contexts — when a recipe says "250 grams of flour," it means the flour should weigh 250g on your kitchen scale.

What Is a Cup?

The cup is a US customary unit of volume equal to 16 tablespoons, 8 fluid ounces, or 236.588 milliliters. Cups can be abbreviated as c or C — for example, 1 cup can be written as 1 c.

One standard US cup is equal to 236.588 milliliters, but for nutrition labeling purposes, the FDA defines one cup as 240 milliliters.^[3] A metric cup is even larger at 250 mL, while in Japan, a cup equals only 200 mL. The cup should not be confused with the metric cup or the teacup, which are different units of volume.
