Common Kg To Cups Chart
Because cups measure volume and kilograms measure weight, the conversion depends on the ingredient’s density. Below are standard conversions for 1 kg of common baking ingredients.
| Ingredient | Density (g/cup) | 1 kg in Cups |
|---|---|---|
| Water | 236.6 g | 4.23 cups |
| All-Purpose Flour | 120.0 g | 8.33 cups |
| Granulated Sugar | 200.0 g | 5.00 cups |
| Butter | 227.0 g | 4.41 cups |
| Brown Sugar | 220.0 g | 4.55 cups |
| Honey | 340.0 g | 2.94 cups |
Cooking & Baking FAQ
Everything you need to know about converting weight to volume, understanding ingredient density, and improving your baking accuracy.
To convert kilograms to cups, you must first convert kilograms to grams (multiply by 1,000), and then divide by the specific ingredient’s density in grams per cup. For example, 1 kg of water (1,000g) divided by 236.59g/cup equals approximately 4.23 cups.
Kilograms measure mass (weight), while cups measure volume. Different ingredients have different densities, meaning they weigh different amounts for the same volume. For example, 1 cup of flour weighs much less (about 120g) than 1 cup of honey (about 340g).
There are approximately 8.33 US cups in 1 kg of all-purpose flour. This is based on the standard density of sifted all-purpose flour, which is about 120 grams per US cup.
A cup is a measure of volume, not weight. In the US customary system, 1 cup is equal to 8 fluid ounces or approximately 236.59 milliliters. Because it measures volume, the weight of a cup varies depending on the substance being measured.
Converting weight (kg) to volume (cups) can introduce inaccuracies in baking because factors like sifting, packing, and humidity change an ingredient’s density. For the most precise baking results, it is always recommended to use a digital kitchen scale and measure by weight.
