How Much Is 490 Grams of Buttermilk in Gallons?
490 grams of buttermilk equals 0.13 gal. Buttermilk has a density of 245g per cup. Because grams measure weight and gallons measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 490 grams of buttermilk
- 1 cup of buttermilk = 245g
- 490g ÷ 245g/cup = 2 cups ÷ 16 = 0.13 gallons
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 Gallon?
For large-batch cooking, 1 US gallon is approximately 3.8 liters. The imperial gallon (4.5 liters) is no longer commonly used in the UK for cooking, as most modern British recipes use metric measurements.
