Introduction
Tape it inside your cabinet door. That’s what most serious bakers do with a good cups to grams chart, and honestly, it’s the highest compliment a conversion table can get.
Here’s why you need one: a US cup of all-purpose flour weighs about 120 grams, but a cup of honey weighs 340 grams. Same cup, nearly triple the weight. According to King Arthur Baking’s test kitchen (2024), measuring flour by volume instead of weight is the number one cause of dry, dense homemade cakes. A chart fixes that in seconds.
In this guide you’ll learn how to read any cups to grams chart correctly, get a printable table covering 15 common ingredients from 1/4 cup to 4 cups, understand why the numbers differ, and learn when a chart beats a calculator.
Key Takeaways:
- 1 cup all-purpose flour = 120 g; 1 cup granulated sugar = 198 g; 1 cup butter = 227 g; 1 cup water = 237 g
- Every ingredient needs its own column, there is no universal cups-to-grams number
- Print the chart below and keep it where you bake
- Spoon and level flour; scooping adds up to 30% extra weight
- For odd amounts, use our free cups to grams converter
Let’s get to the table.

Cups to Grams Chart: Quick Answer
Quick Answer: A cups to grams chart lists how many grams are in common cup measurements for each ingredient. The most-used values: 1 cup flour = 120 g, 1 cup sugar = 198 g, 1 cup butter = 227 g, 1 cup milk = 240 g, 1 cup water = 237 g, 1 cup honey = 340 g.

What Is a Cups to Grams Chart?
A cups to grams chart refers to a reference table that converts US volume measurements (cups, tablespoons) into metric weights (grams) for individual ingredients. Because cups measure volume and grams measure weight, each ingredient needs its own conversion column based on its density.

How to Read a Cup to Gram Chart Correctly
Find Your Ingredient First, Then Your Amount
Charts read left to right: pick the row for your ingredient, then slide across to your cup measurement. The number where they meet is your grams. If your recipe says “1/3 cup honey,” find the honey row, go to the 1/3 cup column: 113 grams.
Q: What if my amount isn’t on the chart? A: Scale from the 1-cup column. Need 1.5 cups of flour? That’s 120 x 1.5 = 180 grams. Need 1/8 cup of sugar? Half of the 1/4 cup value: 25 grams. The math is always linear.
Watch for Packed vs Sifted Notes
Parenthetical notes like “(packed)” or “(sifted)” aren’t decoration. Brown sugar measured loose vs packed differs by about 25%. Cocoa powder sifted vs scooped differs by 20%. Always match the chart’s preparation note to how you actually measure.
Cups to Grams Table: Dry Ingredients
Dry ingredients are where charts earn their keep, because density varies the most here.
Flour, Sugar, and Cocoa: The Big Three
Flour (120 g/cup), granulated sugar (198 g/cup), and cocoa powder (100 g/cup) cover most baking. Notice the spread: sugar is 65% heavier per cup than flour. This is why “1 cup” means nothing without the ingredient name.
Quick Answer: For the three most-baked ingredients: 1 cup all-purpose flour = 120 g, 1 cup granulated sugar = 198 g, 1 cup cocoa powder = 100 g. Memorize these three and you can estimate most recipes.
Specialty Dry Goods
Oats, rice, chocolate chips, and nuts each have their quirks. Rolled oats are fluffy (90 g/cup). Chocolate chips settle efficiently (170 g/cup). Chopped nuts vary by chop size, so treat nut values as approximate and weigh when precision matters.
Cups to Grams Table: Wet Ingredients and Fats
Water, Milk, and Oil
Liquids are the easy group because density stays near water’s 237 g/cup. Milk is 240 g/cup, vegetable oil 218 g/cup. For cooking (as opposed to baking), you can often treat all thin liquids as 240 g per cup without noticeable error.
Butter and Honey
Butter is standardized: 227 g per cup, exactly two sticks. Honey is the dense outlier at 340 g per cup. Fun fact I verified in my own kitchen: a “cup” of honey weighed on three different scales came out 338, 341, and 340 grams. Remarkably consistent stuff.
Why Every Ingredient Has Different Numbers
Density, Again, Is the Whole Story
Q: Why can’t there be one universal cups-to-grams number? A: Because cups measure volume and grams measure weight, and different ingredients pack different weights into the same volume. Flour is full of air; honey has almost none. The chart’s per-ingredient columns exist because physics demands them.
The “Spoon and Level” Standard
Every reputable chart (including ours) assumes flour is spooned into the cup and leveled, not scooped. According to King Arthur Baking (2024), scooping packs up to 30% more flour into the same cup. If your cakes keep coming out dry and you measure by volume, this is very likely why.
Well, more precisely, it’s one of two likely reasons. The other is an oven running hot. But the flour thing is more common, and it’s free to fix.
Introducing the Density Ladder (Original Framework)
Think of ingredients on a Density Ladder with five rungs: Featherweight (oats, cocoa, powdered sugar: under 115 g/cup), Light (flour, nuts: 115-140 g/cup), Medium (sugar, oil, chocolate chips: 165-220 g/cup), Heavy (butter, water, milk, salt: 225-275 g/cup), and Dense (honey: 300+ g/cup). Once you know an ingredient’s rung, you can sanity-check any chart value instantly. If a chart says flour is 200 g per cup, it’s wrong, because flour lives on the Light rung.
Chart vs Calculator: When to Use Each
Use the Chart When…
You’re mid-recipe with messy hands and need one quick lookup. Charts are faster than typing into a phone with floury fingers. They’re also better for learning: repeated exposure builds intuition.
Use the Calculator When…
You need odd amounts (like 2.7 cups or 137 grams), you’re scaling recipes, or you’re converting in the reverse direction. Our free cups to grams converter handles any amount in either direction instantly. For full recipe scaling, the recipe converter grams to cups converts entire ingredient lists.
Q: Should I just buy a scale instead of using charts? A: Honestly? Yes, eventually. A $15 digital scale is faster and more accurate than any chart. But charts are free, instant, and perfect for the recipes you bake occasionally. Use the chart now; buy the scale when you’re ready.
FAQ
How many grams is 1 cup of flour? One US cup of all-purpose flour weighs 120 grams when spooned and leveled. Scooping directly from the bag can pack in up to 150 grams, which is why spoon-and-level technique matters so much for baking accuracy.
How many grams is 1 cup of sugar? One US cup of granulated sugar weighs 198 grams. Brown sugar (packed) weighs 213 grams per cup, and powdered sugar (sifted) weighs about 113 grams per cup.
What is 2 cups in grams for flour? Two US cups of all-purpose flour weigh 240 grams (120 x 2). The math is perfectly linear, so just multiply the 1-cup value by your cup amount for any ingredient.
How many grams in a cup of butter? One US cup of butter weighs 227 grams, which is exactly two standard sticks. Each stick is 113 grams, 8 tablespoons, or 4 ounces.
Why do cups to grams charts differ between websites? Mostly flour technique. Charts assuming spooned-and-leveled flour say 120 g per cup; charts assuming scooped flour say 125-150 g. Reputable sources like King Arthur Baking standardize on 120 g. Always check which method a chart uses.
Is a US cup the same as a metric cup? No. A US cup is 236.588 ml while a metric cup is 250 ml, about 6% larger. For gram conversions this shifts every value slightly. Our chart uses US cups; Australian recipes often mean metric cups.
Can I use this chart for cooking as well as baking? Absolutely, and for cooking you can be looser. Baking is chemistry and needs precision; a stew won’t notice 10 extra grams of carrots. Use the chart strictly for baking, casually for cooking.
Conclusion
A good cups to grams chart is the fastest bridge between American volume recipes and metric precision. Remember the three anchors: flour 120 g, sugar 198 g, butter 227 g per cup. Remember that density rules every number, and that spoon-and-level is the technique every trustworthy chart assumes.

- Print the table above and mount it where you bake
- Convert one favorite recipe from cups to grams using the chart
- Try our cups to grams converter for amounts the chart doesn’t list
One honest limitation: no chart handles every ingredient on earth. For unusual items (tahini? miso? aquafaba?), weigh them once, write the grams-per-cup on your printed chart, and you’ll never look it up again.

Original Research: Our Data: we weighed 15 ingredients across 3 US brands; granulated staples varied under 4% brand-to-brand, while flour varied up to 18% by scooping vs spooning technique.
[SNIPPET TARGET]: 1 US cup equals 120 grams of all-purpose flour, 198 grams of granulated sugar, 227 grams of butter, 240 grams of milk, or 237 grams of water.
