Enter the volume in cups and select the ingredient into the calculator to determine the approximate weight in kilograms.

Cups to Kg Converter

Enter the cups and select an ingredient to calculate the approximate kilograms.

Cups to Kg Formula

The following formula is used to calculate the approximate kilograms from cups for a specific ingredient.

KG = C * GPC / 1000

Variables:

  • KG is the weight in kilograms
  • C is the volume in cups
  • GPC is the grams per cup for the selected ingredient

To calculate kilograms from cups, multiply the number of cups by the ingredient's grams per cup and divide the result by 1000.

What is a Cups to Kg Conversion?

A cups to kg conversion changes a volume measurement into a weight measurement. Because cups measure volume and kilograms measure mass, the conversion depends on the ingredient being measured. Water, flour, sugar, butter, honey, and oil all have different densities, so one cup of each ingredient will not weigh the same. This is why a cups to kg converter uses a typical grams-per-cup value for the selected ingredient.

How to Calculate Cups to Kg?

The following steps outline how to calculate kilograms from cups.


  1. First, determine the volume in cups.
  2. Next, identify the ingredient and its typical grams per cup value.
  3. Multiply the number of cups by the grams per cup.
  4. Divide the result by 1000 to convert grams into kilograms.
  5. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Cups (C) = 2

Ingredient = All-Purpose Flour

Grams Per Cup (GPC) = 120

Using the formula, KG = 2 * 120 / 1000 = 0.24 kg.

Cups to Kg Conversion Table

The table below shows approximate conversions for 1 cup of several common ingredients using typical kitchen conversion factors.

Ingredient Approx. Grams Per Cup 1 Cup in Kg
Water 236.6 g 0.2366 kg
All-Purpose Flour 120 g 0.1200 kg
Granulated Sugar 200 g 0.2000 kg
Butter 227 g 0.2270 kg
Whole Milk 245 g 0.2450 kg
Honey 340 g 0.3400 kg
Olive Oil 215 g 0.2150 kg
Uncooked Long-Grain Rice 195 g 0.1950 kg

In practice, exact weights can vary based on packing, brand, moisture, and measurement method, so these values should be treated as practical approximations for cooking and recipe conversions.
