How Much Is 637 Grams of Buttermilk in Cups?
637 grams of buttermilk equals 2.60 cups. Buttermilk has a density of 245g per cup. Because grams measure weight and cups measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 637 grams of buttermilk
- 1 cup of buttermilk = 245g
- 637g ÷ 245g/cup = 2.6 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

Understanding the Units
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
What is a Cup?
The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.
