# How Many Ounces In A Half Cup – Online Converter

The answer to the question how many ounces in a half cup is 4 fluid ounces in US and 4.1634 ounces in UK.

Cup measurements are a common way to measure ingredients when baking. A cup is defined as eight fluid ounces, or approximately 240 milliliters. It can also be considered a unit of measurement for volume or capacity in cooking and other places where a unit of volume is more convenient than a unit of weight. One cup is equal to two tablespoons or half a fluid ounce. Cup measurements are traditionally used in the United States and Canada, while the metric system is more popular in other places around the world.

Many cooking measurements, such as teaspoons and tablespoons, originate from apothecaries’ system of measurement. According to livestrong.com, this regionally popular system used a liquid pint (a liquid pound) as well as a dry pint and a liquid gallon that were both equal to about eight pounds. The apothecaries’ system was then modified into a U.S.-based system that is still used today by adding a dry quart that equals four liquid pints and a dry gallon of eight dry quarts, both equal to about 32 pounds of liquid.

There are 16 ounces in one U.S. cup of liquid or mass, but this measurement differs for dry measurements because the density of the food has a larger role in the equation. In some cases, one cup of dry materials is equivalent to as much as 48 ounces of liquid.
