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 Milliliter?
Milliliters measure volume and are used worldwide for cooking and baking. For water at room temperature, 1 ml weighs approximately 1 gram, but this relationship does not hold for other ingredients.

If you have a kitchen scale, weighing olive oil gives you an exact starting point for this conversion. If you need to measure by volume instead, use a liquid measuring cup on a flat surface and read the level at eye height.
Very close. Pure liquid densities are consistent across brands, so the ounces to milliliters conversion for olive oil typically varies by less than 2-3%.
The same weight of different ingredients fills different volumes because each ingredient has a different density. An ounce of olive oil fills a different number of milliliters than an ounce of a lighter or heavier ingredient. That is why this converter needs to know which ingredient you are measuring.
