How Much Is 5 Ounces of Buttermilk in Fluid Ounces?
5 ounces of buttermilk equals 4.63 fl oz. That's 141.75g, and Buttermilk has a density of 245g per cup. Because ounces measure weight and fluid ounces measure volume, the result depends on the ingredient's density.
Formula and Step-by-Step
- Start with 5 ounces of buttermilk
- Convert ounces to grams: 5 × 28.35 = 141.75g
- 1 cup of buttermilk = 245g
- 141.75g ÷ 245g/cup = 0.58 cups × 8 = 4.63 fluid ounces
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 an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
What is a Fluid Ounce?
The US fluid ounce (29.574 ml) and the UK fluid ounce (28.413 ml) are different sizes. The UK version is about 4% smaller. This means a UK recipe calling for 8 fl oz gives you 227 ml, while 8 US fl oz gives you 237 ml. The difference is small per ounce but adds up in larger quantities.
