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 a Milliliter?
A milliliter (ml) is a metric unit of volume equal to 1/1000 of a liter. It is the standard volume measurement for cooking in most countries outside the US. One cup equals approximately 236.588 milliliters.
What is an Ounce?
Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

The most accurate way is to weigh water on a kitchen scale. If you are measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height. Liquids settle naturally, so volume measurements are already quite consistent.
Very close. Pure liquid densities are consistent across brands, so the milliliters to ounces conversion for water typically varies by less than 2-3%.
For liquids like water, volume measurements are already quite accurate since liquids settle to a consistent level. A kitchen scale adds precision but the difference is typically small for liquid ingredients.
