how many grams in a cup

If you’ve ever made a recipe that uses cups or tablespoons, you may wonder why they aren’t turning out as expected. This is especially important for baking, as precise measurements are imperative.

This is where using grams comes into play. A chocolate cake using grams will always turn out much better than the same recipe calling for cups. When using grams, the room for error is minimal.

What are grams? 

Grams is a unit of weight used in the metric measurement system. There are one thousand milligrams in one gram. Most countries use the metric system, which measure weight in grams and kilograms. The ingredients you use will usually come in these quantities too. The few countries that don’t use the metric system (United States, Myanmar, and Liberia) use the Imperial measurement system.

How to convert cups to grams (1 gram to cups)

Different ingredients use different units for measurement. Once you work out which unit it falls under, you can then convert them to grams.

For example, there are 1000 grams in a kilogram. Here are the formulas for converting ingredients to grams-

  • Milligram: 0.001 gram
  • Ounce: 28.35 grams
  • Fluid ounce: 29.57 grams
  • Kilogram: 1000 grams
  • Stone: 6350.20 grams
  • U.S. ton: 907,185 grams

How many grams are in a cup

Flour is a common ingredient used in baking. Based on research and evidence, there are 120 grams in one cup of flour.

If a vanilla cake recipe calls for 3 cups of flour, you can use this for the conversion-

120 grams x 3 = 360 grams of flour for the recipe.

Here is a handy conversion chart to use. See below for more conversions for popular ingredients.

Is it best to use a kitchen scale or measuring cups for baking? 

A kitchen scale is a highly recommended option for measuring ingredients for baking or any recipe. Benefits of using a scale include:

  • Accuracy– There is very little room for error and the weight is as accurate as can be.
  • Utilizes all kinds of units- A basic scale can offer fluid ounces, ounces, ml, and grams.
  • No mess– There are no measuring cups to wash or bowls to rinse out.

Hence, a kitchen scale is a better option than measuring cups. 

What is a scant cup?

A cup that isn’t firmly packed with its dry ingredients, for example, flour or sugar, is known as a scant cup. We often use it when baking desserts (like brownies or a chocolate cake) and when sugar is involved- e.g. a scant cup of brown sugar.

How many grams are in half a cup?

Using flour (a dry ingredient) as a base, there are 60 grams in half a cup. Again, this would differ based on what the half cup contains.

For a liquid ingredient, like milk, there are 125 grams.

  1. Hi, there,
    Just a little confused by this.
    “Flour is a common ingredient used in baking. Based on research and evidence, there are 240 grams in one cup of flour.” I’ve always read that 1 cup flour is in the 120 gram range. Just wondering if there’s an error there.
    Thanks so much.

    1. Hi Linda- apologies there was an error with the article when posted. It should be amended now- 120 grams per cups is correct.

  2. Thank you so much for all the work that you have put into this, Arman. I have so needed this for a very long time, as I never retain any conversions in my head! I am printing it out for easy referencing.
    Absolutely love your innovative, easy to follow recipes and ideas.
