Whether you’re following a US recipe that lists ingredients in cups or a European one that uses grams, getting the right amount matters. Our cup to gram converter handles the math instantly for over 140 ingredients — from all-purpose flour and granulated sugar to butter, honey, and cocoa powder. Just type a number, pick your ingredient, and see the gram value in real time. The swap button lets you convert grams to cups just as easily, so you can move between both measurements without switching pages.

Unlike generic converters that assume “1 cup = 240 grams” for everything, this tool uses ingredient-specific reference weights. That means 1 cup of flour weighs about 125 grams, while 1 cup of sugar weighs about 200 grams — and both values are correct.

How to Convert Cups to Grams

Converting cups to grams is straightforward once you know the ingredient’s density. Volume (cups) measures how much space an ingredient takes up; weight (grams) measures how heavy it is. Because every ingredient has a different density, the same cup will weigh different amounts depending on what you’re measuring.

The formula is simple:

grams = cups × grams per cup (for that ingredient)

For example:

• 1 cup all-purpose flour = 125 g → 2 cups = 250 g
• 1 cup granulated sugar = 200 g → ½ cup = 100 g
• 1 cup butter = 227 g → ¼ cup = 57 g
• 1 cup honey = 340 g → ½ cup = 170 g

Our converter does this calculation automatically when you select an ingredient from the dropdown.

Common Cup to Gram Conversions

Here’s a quick reference for the most-searched ingredients. For a full list, use the interactive table above.

Ingredient weights on this page follow reference values published by the USDA FoodData Central database.

Cups to Grams for Flour

Cups	All-Purpose Flour	Bread Flour	Whole Wheat Flour
¼ cup	31 g	32 g	30 g
⅓ cup	42 g	42 g	40 g
½ cup	63 g	64 g	60 g
1 cup	125 g	127 g	120 g
2 cups	250 g	254 g	240 g

Note: Scooping method changes the result. A “spooned and leveled” cup of flour weighs about 125 g, while a “scooped” cup can weigh up to 150 g. For best accuracy, spoon flour into the cup and level it off with a knife.

Cups to Grams for Sugar

Cups	Granulated	Brown (packed)	Powdered
¼ cup	50 g	55 g	30 g
½ cup	100 g	110 g	60 g
1 cup	200 g	220 g	120 g

Cups to Grams for Butter and Fats

Cups	Butter	Coconut Oil	Vegetable Oil
¼ cup	57 g	55 g	55 g
½ cup	113 g	109 g	109 g
1 cup	227 g	218 g	218 g

Cups to Grams for Liquids

Cups	Water	Milk	Honey
¼ cup	59 g	61 g	85 g
½ cup	118 g	122 g	170 g
1 cup	237 g	244 g	340 g

Why Ingredient-Specific Weights Matter

If you’ve ever baked a cake that came out dry, dense, or crumbly, the culprit is often too much flour. Most people scoop flour directly from the bag — which can pack in 20–30% more than the recipe intended.

A recipe that says “1 cup flour” usually means 125 grams, but a scooped cup can weigh 150 g or more. That’s the difference between a light, tender cake and a heavy brick.

Using a cup to gram converter removes the guesswork. Weighing your ingredients in grams is the single biggest upgrade you can make to your baking — professional bakers do it for a reason. It’s faster, more accurate, and produces consistent results every single time.

For the most precise results:

1. Use a digital kitchen scale (any $15–$30 scale works)
2. Place your bowl on the scale, press “tare” to zero it
3. Spoon the ingredient in until you hit the gram target
4. No measuring cups needed

Converting Grams to Cups

The reverse conversion works the same way, just in the opposite direction. Select “Grams” as your starting unit (or click the swap button), enter the gram value, and the tool shows you the equivalent in cups.

Formula:
cups = grams ÷ grams per cup (for that ingredient)

Examples:

• 250 g all-purpose flour = 2 cups
• 200 g granulated sugar = 1 cup
• 113 g butter = ½ cup
• 100 g honey ≈ 0.29 cups (about ¼ cup + 1 tbsp)

This is especially useful when you’re working from a European or Australian recipe that lists everything in grams, but your measuring cups are in US units.
