Buttermilk in Grams: 1 Cup, ½ Cup Conversion Table
1 cup of buttermilk weighs 240 grams, very close to the weight of water. Buttermilk is almost always measured in cups in recipes, but grams are more precise — especially when halving or quartering a recipe. Don't substitute regular milk without adding acid (1 tbsp lemon juice per cup) or the leavening reaction won't activate.
For the most accurate results, weigh your buttermilk with a digital kitchen scale — the values below assume a level, unpacked cup.

Who is this useful for?
If you're an international cook following US-based recipes, you'll often encounter cup measurements for buttermilk. However, many countries — including those in Europe and Asia — primarily use grams for precision. Converting buttermilk to grams ensures consistent and reliable results, whether you're baking or cooking.
Why accuracy matters for buttermilk
Precision is especially important when using buttermilk in baking and cooking. Even small variations in weight can impact the texture, consistency, and flavour of your dish. For example, too much buttermilk in a recipe can make baked goods dense, while too little may cause them to be too dry or crumbly.
Common mistakes to avoid when cooking with buttermilk
- Using milk instead of buttermilk without adjusting baking soda or acidity.
- Skipping buttermilk in recipes that rely on its acidity for leavening.
- Letting buttermilk sit out too long, causing it to separate.
