What is a grams to cups conversion chart?

A reference table showing how many cups a gram weight equals for baking ingredients like flour, sugar, and butter.

Why do different ingredients have different cup weights?

Because ingredients have different densities. One cup of flour weighs about 125g while one cup of honey weighs about 340g.

Can I use one chart for all ingredients?

No. A chart works for one ingredient at a time. Use ingredient-specific pages for accurate results.

The Ultimate Grams to Cups Conversion Chart

8 min read

Why grams-to-cups conversion depends on ingredient density. A cup of flour weighs far less than a cup of honey — one generic number won't work for every recipe.

Whether you're following an international recipe or just trying to measure properly, converting by weight relies heavily on what you are actually measuring. Below is a comprehensive reference chart to help you accurately convert your grams to cups for common baking ingredients.

Reference Table — Grams to Cups: Common Baking Ingredients

Ingredient	Grams per US Cup	Example: 100g = X cups
All-Purpose Flour	125g	0.80 cups
Bread Flour	127g	0.79 cups
Cake Flour	114g	0.88 cups
Granulated Sugar	200g	0.50 cups
Brown Sugar (packed)	220g	0.45 cups
Powdered Sugar	120g	0.83 cups
Butter	227g	0.44 cups
Rolled Oats	90g	1.11 cups
Whole Milk	244g	0.41 cups
Honey	340g	0.29 cups

All values use US standard cups (236.6 ml). Measuring method affects results.

Why the Numbers Differ

Explain density differences between dry vs liquid ingredients. Liquid ingredients often have densities close to water (237g per cup), but dry ingredients vary significantly because they trap air between their particles.

Packed vs loose measurements can also completely change the mass of an ingredient. For instance, brown sugar is almost always measured packed, making a single cup weigh significantly more than granulated sugar.

Sifted vs unsifted flour is another common source of variation. A cup of sifted flour weighs less because it's aerated, whereas unsifted flour from the bag is more compact and heavier.

How to Use This Chart

Identify the correct ingredient: Ensure you match exactly what you are using (e.g., bread flour vs all-purpose).
Find its grams-per-cup reference: Locate the density in our table above.
Divide your gram amount by that number: If you have 250g of all-purpose flour, divide 250 by 125.
Round to the nearest practical measure: In this case, exactly 2 cups!

Measuring tip: Spoon flour into the cup and level off instead of scooping directly from the bag to avoid packing and over-measuring.

Common Mistakes

Using one density for all ingredients
A cup of oats is only 90g, while a cup of honey is 340g. Using a uniform conversion factor will ruin your baked goods.

Scooping instead of spooning dry ingredients
Scooping packs the flour down into the cup, which can add up to 20% more weight to your measurement.

Not accounting for packed vs loose brown sugar
Brown sugar is expected to be packed in most American recipes. Using loose brown sugar means you won't have enough sweetness.
