How Much Is 2 Fluid Ounces of Buttermilk in Grams?
2 fluid ounces of buttermilk weighs 61.25 g. This is based on buttermilk having a density of 245g per cup. Because fluid ounces measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 2 fluid ounces.
Formula and Step-by-Step
- Start with 2 fluid ounces of buttermilk
- 1 fluid ounce of buttermilk = 30.63g
- 2 × 30.63 = 61.25g
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Mental Math Shortcut
Quick check: 2 fluid ounces is just double the single-fluid ounce weight. 1 fluid ounce = 30.63g, so 2 = 61.25g.
Measuring Tip
Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units
What is a Fluid Ounce?
A US fluid ounce (fl oz) is a unit of volume equal to 29.574 milliliters or 1/8 of a cup. It measures liquid volume and should not be confused with the ounce (oz), which measures weight.
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.
