From Cups to Grams: A Guide to Mastering Kitchen Conversions
Published on September 10, 2024 by UnitConvertersOnline Team

Baking is a science, and precision is key. One of the biggest challenges for home bakers is converting recipes from different regions, especially when they mix volume measurements (like cups) with weight measurements (like grams). This guide will help you become a conversion master.
Why You Can't Directly Convert Cups to Grams
The core problem is density. A cup is a measure of volume, while a gram is a measure of weight. A cup of lead will weigh much more than a cup of feathers. The same applies in the kitchen:
- 1 US cup of all-purpose flour ≈ 120 grams
- 1 US cup of granulated sugar ≈ 200 grams
- 1 US cup of water or milk ≈ 240 grams (since 1 mL of water weighs 1g)
This is why professional bakers always use a kitchen scale. It's the only way to guarantee consistent results.
Essential Tools
For best results, we recommend having these tools on hand:
- A digital kitchen scale (for grams/ounces)
- Liquid measuring cups (for ml/liters)
- Dry measuring cups and spoons (for cups/tbsp/tsp)
