Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 236.59g/cup × 236.588 = milliliters

Start with 8 ounces of water
Convert ounces to grams: 8 × 28.35 = 226.80g
1 cup of water = 236.59g
226.80g ÷ 236.59g/cup = 0.96 cups × 236.588 = 226.79 milliliters

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.
