What is 390 Grams in Cups?

On average, 390 grams ≈ 1.6484 US cups
(390 grams of water = 1.6484 cups exactly)

Water

390 g = 1.6484 cups

All-Purpose Flour

390 g = 3.12 cups

Granulated Sugar

390 g = 1.95 cups

Butter

390 g = 1.7181 cups

Honey

390 g = 1.1471 cups

Milk

390 g = 1.625 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 390 grams of honey fits in 1.1471 cups while the same weight of flour spreads across 3.12 cups.

How to Convert 390 Grams to Cups

Step 1: Identify Your Ingredient First

Unlike a simple unit-to-unit conversion, grams-to-cups isn’t a single fixed formula. The answer for 390 grams depends entirely on what you’re measuring. The general formula is:

Cups = 390 ÷ (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 390 grams of water is approximately 390 ÷ 240 = 1.6484 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 = 390 ÷ 236.59 = 1.6484 cups

That means 390 grams of water equals about 1.6484 US cups. Milk is very close at 1.625 cups.

Step 3: Worked Example with Flour

Goal: Convert 390 grams of all-purpose flour to cups

1. Look up the flour density factor:

All-purpose flour ≈ 125 g/cup

2. Divide:

390 ÷ 125 = 3.12 cups

Answer: 390 grams of all-purpose flour ≈ 3.12 cups.

390 Grams in Common Recipes

Here’s what 390 grams works out to in cups for the ingredients you’ll use most in real cooking and baking:

🍞 Bread Baking (Bread Flour)

390 g = 3.0 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)

390 g = 3.4211 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)

390 g = 1.7727 cups
Brown sugar is measured packed — pressed firmly into the cup. Loose-packed brown sugar will read about 15% lighter.

🥞 Pancakes & Muffins (Milk)

390 g = 1.625 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

390 g = 1.1471 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)

390 g = 1.7181 cups
In the US, one cup of butter = 2 sticks = 227 g. Convenient reference: 113 g ≈ 1 stick ≈ ½ cup.

🌾 Oatmeal (Rolled Oats)

390 g = 4.3333 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)

390 g = 1.95 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)

390 g = 4.875 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 390 Grams Without a Kitchen Scale

Missing a scale handy? You can still approximate 390 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. 390 grams of water ≈ 1.6484 US cups ≈ 390 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): 390 grams ≈ 26.375 tablespoons ≈ 79.12 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). 390 g of AP flour ≈ 3.12 cups.
  • Granulated sugar: Sugar packs predictably, so cup measurements stay close to accurate. 390 g ≈ 1.95 cups.
  • Brown sugar: Pack firmly into the cup. 390 g packed ≈ 1.7727 cups.
  • Butter: Use the wrapper markings (in the US, 1 stick = 113 g = ½ cup). 390 g ≈ 1.7181 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. Unlike 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 390 grams, it’s telling you exactly how much mass to add — no ambiguity. That’s why professional bakers and serious home cooks reach for 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 measures 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 390 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 390 grams (a mass) into cups (a volume), you have to apply the ingredient’s density. Water is the baseline at 1 g/mL, which puts 390 grams of water at exactly 1.6484 US cups. Honey is roughly 1.4× denser, so 390 grams of honey fits in only 1.1471 cups. Flour is much less dense in cup form (lots of air between particles), so 390 grams of flour spreads to 3.12 cups — about double the water volume.

FAQ: 390 Grams to Cups

❓ How many cups is 390 grams?

The answer depends on the ingredient’s density. For 390 grams:
  • Water: 1.6484 cups
  • All-purpose flour: 3.12 cups
  • Granulated sugar: 1.95 cups
  • Butter: 1.7181 cups
  • Honey: 1.1471 cups
  • Table salt: 1.4286 cups

⚖️ Why does 390 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 390 g of honey (1.1471 cups) takes much less volume than 390 g of flour (3.12 cups).

📏 What’s the formula to convert 390 grams to cups?

Use simple division:
Cups = Grams ÷ (grams per cup)
For 390 grams of water (236.59 g/cup):
390 ÷ 236.59 = 1.6484 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 390 grams of water = 1.6484 US cups but only 1.56 metric cups.

🎯 Is volume measurement accurate enough for 390 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.
