What is 307 Grams in Cups?

On average, 307 grams ≈ 1.2976 US cups
(307 grams of water = 1.2976 cups exactly)

Water

307 g = 1.2976 cups

All-Purpose Flour

307 g = 2.456 cups

Granulated Sugar

307 g = 1.535 cups

Butter

307 g = 1.3524 cups

Honey

307 g = 0.9029 cups

Milk

307 g = 1.2792 cups
Why these numbers differ: A US cup is a fixed volume (236.588 mL), but every ingredient has its own density. Honey is heavy and dense, so the same weight in grams fills a smaller cup volume than something light and airy like flour. That’s why 307 grams of honey fits in 0.9029 cups while the same weight of flour spreads across 2.456 cups.

How to Convert 307 Grams to Cups

Step 1: Identify Your Ingredient First

Different from a simple unit-to-unit conversion, grams-to-cups isn’t a single fixed formula. The answer for 307 grams depends entirely on what you’re measuring. The general formula is:

Cups = 307 ÷ (grams per cup)

Where the divisor is the ingredient’s density expressed in grams per US cup (g/cup). Note that this is division — to find cups when you know grams, you divide weight by the density factor. The opposite direction (cups to grams) uses multiplication.

Quick mental shortcut: For water and milk, the divisor is roughly 240 (water is 236.59, milk is 240). So 307 grams of water is approximately 307 ÷ 240 = 1.2976 cups — good enough for everyday cooking.

Step 2: Worked Example with Water

Water is the simplest case. One US cup holds 236.59 mL of water, and water has a density of 1 g/mL, so:

Cups of water = 307 ÷ 236.59 = 1.2976 cups

That means 307 grams of water equals about 1.2976 US cups. Milk is very close at 1.2792 cups.

Step 3: Worked Example with Flour

Goal: Convert 307 grams of all-purpose flour to cups

1. Look up the flour density factor:

All-purpose flour ≈ 125 g/cup

2. Divide:

307 ÷ 125 = 2.456 cups

Answer: 307 grams of all-purpose flour ≈ 2.456 cups.

307 Grams in Common Recipes

Here’s what 307 grams looks like in cups for the ingredients you’ll use most in real cooking and baking:

🍞 Bread Baking (Bread Flour)

307 g = 2.3615 cups
Bread flour is denser than all-purpose flour because it has more protein. Use a kitchen scale for the most accurate hydration ratios.

🎂 Cake Baking (Cake Flour)

307 g = 2.693 cups
Cake flour is lighter and finer than AP flour, so the same weight fills a larger cup volume. Sift before measuring for best results.

🍪 Cookies (Brown Sugar, packed)

307 g = 1.3955 cups
Brown sugar is measured packed — pressed firmly into the cup. Loose-packed brown sugar will read about 15% lighter.

🥞 Pancakes & Muffins (Milk)

307 g = 1.2792 cups
Milk is slightly denser than water (about 1.03 g/mL). For most recipes you can substitute milk and water 1:1 by weight without recalculating.

🍯 Sweetening with Honey

307 g = 0.9029 cups
Honey is much denser than sugar — the same gram weight occupies far less volume. Substituting honey for sugar 1:1 by weight changes texture.

🧈 Butter (softened or melted)

307 g = 1.3524 cups
In the US, one cup of butter = 2 sticks = 227 g. Convenient reference: 113 g ≈ 1 stick ≈ ½ cup.

🌾 Oatmeal (Rolled Oats)

307 g = 3.4111 cups
Rolled oats are airy, so a cup weighs only about 90 g. Steel-cut oats are denser and won’t follow this conversion.

🍚 Rice (uncooked)

307 g = 1.535 cups
Uncooked long-grain white rice is about 200 g/cup. Rice triples in volume when cooked, so plan portions accordingly.

☕ Espresso/Drip Coffee (Ground)

307 g = 3.8375 cups
A standard drip coffee uses ~10 g per cup of brewed coffee. For pour-over, a 1:16 ratio is a great starting point.

Measuring 307 Grams Without a Kitchen Scale

Don’t have a scale handy? You can still approximate 307 grams using common kitchen tools — just remember the result will be a volume estimate, and accuracy depends heavily on the ingredient.

Use Measuring Cups for Liquids

For water, milk, and other liquids with density close to 1 g/mL, you can measure directly. 307 grams of water ≈ 1.2976 US cups ≈ 307 mL. Most glass liquid-measuring cups have mL markings that make this easy.

Use Tablespoons and Teaspoons for Small Amounts

For dry powders like flour, sugar, or salt, tablespoons can replace a scale if you’re careful to level off each spoonful with a flat edge. As a baseline (for water): 307 grams ≈ 20.761 tablespoons ≈ 62.28 teaspoons.

Volume-First Reference (Ingredient-Specific)

  • Flour: Spoon flour into the cup, then level — don’t scoop with the cup (that compresses and adds ~25% weight). 307 g of AP flour ≈ 2.456 cups.
  • Granulated sugar: Sugar packs predictably, so cup measurements stay close to accurate. 307 g ≈ 1.535 cups.
  • Brown sugar: Pack firmly into the cup. 307 g packed ≈ 1.3955 cups.
  • Butter: Use the wrapper markings (in the US, 1 stick = 113 g = ½ cup). 307 g ≈ 1.3524 cups.
Pro Tip: Even a basic $15 digital kitchen scale eliminates guesswork. For bread, pastry, and chocolate work — where small differences matter — weighing is non-negotiable. Volume measures vary up to 20% depending on how aerated, packed, or settled the ingredient is.

Grams & Cups: A Cook’s Primer

The Gram — A Universal Weight

A gram (g) is the metric system’s base unit of mass, equal to one-thousandth of a kilogram. Different from a cup, a gram is identical anywhere in the world and doesn’t change based on how an ingredient is scooped, packed, or sifted. When a recipe specifies 307 grams, it’s telling you exactly how much mass to add — no ambiguity. That’s why professional bakers and serious home cooks prefer weighing over volume measuring.

The Cup — A Familiar Volume

A cup is a unit of volume used in cooking, especially in the United States. It represents how much space an ingredient occupies, not how much it weighs. Cups come in a few different sizes depending on which standard you’re working from, so converting 307 grams to cups depends on which “cup” your recipe is referring to.

US Customary Cup

236.588 mL. Used in nearly all American recipes and on US nutrition labels.

US Legal Cup

240 mL. Defined by FDA for nutrition labeling. Slightly larger than the customary cup.

Metric Cup

Exactly 250 mL. Standard in Canada, Australia, New Zealand, and many European countries.

UK Imperial Cup

284.131 mL (½ imperial pint). Mostly historical now — modern UK recipes typically use weight or mL.

Why Density Drives the Conversion

Density is mass per unit of volume. To turn 307 grams (a mass) into cups (a volume), you must use the ingredient’s density. Water is the baseline at 1 g/mL, which puts 307 grams of water at exactly 1.2976 US cups. Honey is roughly 1.4× denser, so 307 grams of honey fits in only 0.9029 cups. Flour is much less dense in cup form (lots of air between particles), so 307 grams of flour spreads to 2.456 cups — about double the water volume.

FAQ: 307 Grams to Cups

❓ How many cups is 307 grams?

The cup volume depends on the ingredient’s density. For 307 grams:
  • Water: 1.2976 cups
  • All-purpose flour: 2.456 cups
  • Granulated sugar: 1.535 cups
  • Butter: 1.3524 cups
  • Honey: 0.9029 cups
  • Table salt: 1.1245 cups

⚖️ Why does 307 grams of different ingredients fill different cup volumes?

Because grams measure weight while cups measure volume. The same weight of a dense ingredient like honey takes up less space than the same weight of a light, airy ingredient like flour. The cup itself doesn’t change — only what fills it changes. Honey is roughly 3.4× denser than flour in a measuring cup, which is why 307 g of honey (0.9029 cups) takes much less volume than 307 g of flour (2.456 cups).

📏 What’s the formula to convert 307 grams to cups?

Use simple division:
Cups = Grams ÷ (grams per cup)
For 307 grams of water (236.59 g/cup):
307 ÷ 236.59 = 1.2976 cups.
Swap in the right density value for whichever ingredient you’re working with — see the cheat sheet above.

🥛 Is the answer the same for a metric cup vs. a US cup?

Close, but not identical. A US customary cup holds 236.588 mL; a metric cup (used in Australia, Canada, New Zealand, and parts of Europe) is exactly 250 mL — a 5.7% difference. The US legal cup used on nutrition labels is 240 mL. The traditional UK imperial cup (284.131 mL) is noticeably larger and is rarely used in modern recipes. So 307 grams of water = 1.2976 US cups but only 1.228 metric cups.

🎯 Is volume measurement accurate enough for 307 grams of an ingredient?

For everyday cooking, yes. For baking — especially anything with flour, leavening agents, or precise hydration ratios — a digital scale is more reliable. Volume measures vary by 15-25% depending on how packed, sifted, or settled an ingredient is. Weight does not.
Tip: If you must use volume for flour, spoon the flour into the cup and level it off with a knife. Scooping the cup directly into the flour bag can pack in 25-50% more flour than the recipe expects.
