How Much Is 300 Grams in Cups?

300 grams of all-purpose flour is about 2⅜ cups. That number changes with the ingredient, because grams measure weight while cups measure volume. The table below shows 300g converted for 20 ingredients people search for most.

Why the Cup Value Changes by Ingredient

300g of flour and 300g of honey have identical mass, but flour is airy while honey is thick and heavy. That difference in density, not the weight itself, decides how much space each one takes up in a cup. A cup is a fixed volume, so a lighter ingredient needs more of it to reach the same weight, and a heavier ingredient needs less.

This is also why a single all-purpose grams to cups converter can't use one shared number for every ingredient. Each row in the table above is calculated from that ingredient's own density, sourced from USDA FoodData Central where available.

How This Conversion Is Calculated

cups = grams ÷ grams per cup

Every value on this page comes from that formula. For all-purpose flour, 125g fills one US cup, so 300g of flour divided by 125 gives 2.40 cups. Tablespoon and teaspoon figures scale from the cup result: 1 cup equals 16 tablespoons and 48 teaspoons, so multiplying the cup value by those factors gives the spoon measurements shown in the converter above.

Sifted: 115g. Scooped and packed: up to 150g. Recipes that specify sifted or packed flour will land on a different cup value even at the same 300g, since sifting and packing change how much air sits between the particles.

US, Metric, and Imperial Cups at 300g

Not every "cup" holds the same volume. A US customary cup is 236.588ml, a metric cup is 250ml, and an imperial (UK) cup is 284.131ml. That difference shifts the cup count even when the gram amount and the ingredient stay the same.

300g of all-purpose flour: 2⅜ US Customary cups, 2¼ Metric cups, 2 Imperial (UK) cups.

Measuring 300g Without a Scale

Spoon-and-level versus scoop-and-pack measuring methodsSpoon & LevelScoop & PackKitchen Scale
  • Most accurate

    A kitchen scale reads 300g directly and removes scooping error entirely.

  • Dry ingredients

    Spoon the flour into the cup, then level it off with a straight edge. Never scoop directly from the bag — that packs it down and adds extra weight.

  • Liquids

    Pour into a liquid measuring cup and read the line at eye level, not from above.

  • Packed ingredients

    Brown sugar and similar ingredients should be pressed firmly if a recipe calls for a packed cup.

Frequently Asked Questions

How much is 300 grams in cups?+

It depends on the ingredient. For all-purpose flour, 300g is about 2.40 cups. Check the table above for other common ingredients.

Is 300 grams the same in cups for every ingredient?+

No. Cups measure volume and grams measure weight, so the cup value changes based on how dense the ingredient is.

What's a quick way to measure 300 grams without a scale?+

Use the fraction cup value shown for your specific ingredient in the table above, measured with a spoon-and-level dry cup.

Is 300 grams the same as 300 milliliters?+

Close only for water. 300g of water is about 301ml, since water's density is close to 1g per milliliter. Other ingredients weigh differently per milliliter.
