How Much Is 490 Grams of Buttermilk in Fluid Ounces?

490 grams of buttermilk equals 16.00 fl oz. Buttermilk has a density of 245g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.

Formula and Step-by-Step

grams ÷ 245g/cup × 8 = fluid ounces
  1. Start with 490 grams of buttermilk
  2. 1 cup of buttermilk = 245g
  3. 490g ÷ 245g/cup = 2 cups × 8 = 16.00 fluid ounces

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

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 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 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.

Frequently Asked Questions

About 16.00 fl oz, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Divide the grams by 245 (grams per cup) to get cups, then multiply by 8 to get fluid ounces. For 490 grams: 490 ÷ 245 = 2 cups × 8 = 16.00 fl oz.
For the most accurate results, weigh buttermilk on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of buttermilk changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 16.00 fl oz ÷ 8 = 2 cups, then 2 × 245g/cup = 490g. Or use the Fluid Ounces to Grams converter.
