Tips
Use kitchen scales to weigh in grams for the most accurate baking results — then use this tool to understand the cup equivalent.
When converting grams to cups, always select the correct ingredient — flour, sugar and butter have very different densities.
If your recipe uses US cups, use the US cup setting (236ml). If it's from a UK or Australian cookbook, use the 250ml cup setting.
For liquids like milk and water, you can also measure ml directly — 1ml of water = 1 gram.
About this grams to cups tool
Converting grams to cups is the reverse of the more common cups-to-grams calculation, and it comes up whenever you want to understand a recipe in cup terms or when you have weighed an ingredient and need to know the cup equivalent.
The key challenge is that grams measure weight while cups measure volume. Different ingredients have very different densities: one cup of plain flour weighs 125 grams, while one cup of caster sugar weighs 200 grams. This means you cannot simply divide grams by a single number — you need the specific density of the ingredient you are converting.
This grams to cups converter is ingredient-aware, using the actual measured density of each ingredient rather than applying a generic factor. It covers 27 common baking and cooking ingredients including all major flour types, sugars, fats, liquids and grains.
It also supports both US cups (236.6ml) and UK, Australian and metric cups (250ml), which differ by approximately 5%. This matters in precision baking: 250g of flour is 2 US cups but only 1.9 UK cups.
