*The number of grams in a cup is, unfortunately, not a simple answer. There are several factors to consider, including the size of the cup and the weight of the ingredients. Working in grams is a great way to improve baking accuracy, so here we will discuss exactly how to convert cups into grams for a variety of liquid and dry ingredients.*

## How many grams are in a cup?

**The amount of grams in a US cup depends on the ingredients the cup is holding**. This is because different ingredients have different weights. For example:

**1 cup of flour weighs 120 grams; however**, **1 cup of milk weighs 240 grams**.

This is because milk is heavier than flour, even though they occupy the same amount of space in the cup.

The charts below will assist you in converting cups to grams based on the weight of a variety of commonly used cooking and baking ingredients.

## What are grams?

Grams (g or gm) is a unit of weight or mass used in the metric measurement system. There are 1000 milligrams in one gram and 1000 grams in 1 kilogram. Most countries recognise this form of measurement. The ingredients you buy will usually come in these quantities too.

The United States uses the US customary system of measurement which is based on the imperial system. Weight is measured in ounces instead, but can also be converted to grams.

## What is a cup?

“Cups” are a unit of measurement that is accepted by all systems of measurement. The actual capacity of a cup varies slightly from country to country.

In the US customary system of measurement a standard cup is half a pint, which equates to 16 tablespoons or 240 milliliters. In the metric system, a cup is equal to 250 millilitres.

## How many grams in a liquid cup?

Most liquid ingredients (water, milk, tea etc) have a very similar weight, so a more universal conversion can be calculated for any liquid.

1 milliliter of most liquids equates to 1 gram of weight, as represented in the chart below. e.g. 1 US cup = 240g = 240ml.

If adjusting for a metric cup (Australia, international), there will be 250 g in a cup. A UK imperial cup has the capacity for 284 g of a liquid.

Cup (Liquid) | Grams |

1/8 cup | 30 g |

1/4 cup | 60 g |

1/3 cup | 80 g |

1/2 cup | 120 g |

1 cup | 240 g |

2 cups | 480 g |

3 cups | 720 g |

## How many grams in a US cup of dry ingredients?

Dry ingredients, however, can be of varying weight based on their mass and density. A chart has also been included to help you calculate popular dry ingredient conversions.

Ingredient | Grams | US Cups |

wheat flour | 130 g | 1 cup |

almond flour | 100 g | 1 cup |

coconut flour | 120 g | 1 cup |

granulated sugar | 200 g | 1 cup |

caster sugar | 225 g | 1 cup |

powdered sugar | 125 g | 1 cup |

brown sugar | 190 g | 1 cup |

cocoa powder | 90 g | 1 cup |

sultanas | 200 g | 1 cup |

chocolate chips | 170 g | 1 cup |

## Can you measure grams with a scale?

A kitchen scale is a highly recommended option for measuring ingredients for baking or cooking. Benefits of using a kitchen 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.

Hello Arman!

Thank you so much for your guidance. I prefer to weigh my ingredients, but since your recipes are given in cups, I need to convert either to grams, ounces or pounds.

For example, when you say “1 1/2 cups of flour’, that would be equivalent to:

130g (US)

148g (Metric)

175g (UK)

I’d like to know which system of measurement you use in all your recipes (US, International Metric, UK)?

Hello Adeline! We use US cups 🙂

A vexing question..trying to work out how many grams in a stick of butter required in American recipes. 115 or 125?

Can you help with this measurement. Thank you.

Hi! It is actually 113 grams 🙂

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.

Kind regards.

Jules.

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.

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