How Much Is 250 Milliliters of Water in Ounces?
250 milliliters of water weighs 8.82 oz. This is based on water having a density of 236.59g per cup. Because milliliters measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 250 milliliters.
Formula and Step-by-Step
- Start with 250 milliliters of water
- 1 milliliter of water = 1g
- 250 × 1 = 250.00g
- Convert grams to ounces: 250.00 ÷ 28.3495 = 8.82 oz
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 Milliliter?
Most kitchen measuring cups outside the US are marked in milliliters. A standard metric cup is 250 ml. When converting American recipes, 1 US cup = 236.588 ml.
