## Fluid Ounce Definition

A fluid ounce (abbreviated fl oz, fl. oz., or fl. oz.) is a unit of volume. It is equal to about 28.41 ml in the imperial system or about 29.57 ml in the US system. The fluid ounce is sometimes referred to simply as an “ounce” in applications where its use is implied.

## Cup Definition

The cup is an English unit of volume, most commonly associated with cooking and serving sizes. It is traditionally equal to half a fluid pint in US customary or British Imperial units, but is now defined separately in metric terms in values between 1⁄5 and 1⁄4 of a liter.

Because actual drinking glasses can differ greatly from the size of this unit, standard measuring cups are often used instead. In the United States, the customary cup is half a fluid pint or 8 US customary fluid ounces. A customary cup equals 236.5882365 milliliters.

## 16 ounces equals 2 cups.

Although cups and ounces are units of measure in the same system, converting between the two can sometimes be a bit difficult.

However, both 2 cups and 16 ounces are common measurements, so it can be very helpful to get a feel for the two and learn how to convert between them.

One US ounce equals 0.125 cups. This means that to find how many cups are in a certain number of ounces, you must divide the number of ounces by eight.

For example, when calculating how many cups are in 16 ounces, you would divide 16 by eight.

The answer, which is 2, tells you that there are 2 cups in 16 ounces.

You can also reverse the equation to find how many ounces are in any number of cups. For this, you would simply need to multiply the number of cups by eight.

For example, if you have 2 cups, you would multiply 2 by 8. The answer, which is 16, tells you that there are 16 ounces in 2 cups.

This equation also tells us that there are 8 ounces in a single cup.

## A volume of cup does not equal volume cup!

It’s fun to discover that just as a pancake doesn’t always equal a pancake, a cup may not mean a cup.

In the US, there are two main cup volumes used:

- Legal Cup: The measurement used in recipes, food labeling, and serving sizes. It is defined in United States law as 240 milliliters. That’s the one we used in the fluid ounces to cups converter and ounces to cups conversion table above!
- Regular glass: slightly different (contains 236 ml) than a legal glass, equals half a liquid pint.

But you can also find yourself with a cup of coffee: this cup is very different, since it contains only 118 ml. It is a measure of coffee made with 148 ml of water.

Outside of the United States, it’s even more fun. We can differentiate many more cups and therefore many more conversions from fluid ounces to cups:

- Metric cup – is slightly larger than a legal cup and contains 250 ml.
- UK Cup: technically half an imperial pint, around 284.13ml (one imperial pint = 568.26ml).
- Japanese Cup: Legally equivalent to 2,401/13,310 litres, it means 200ml and is still used to describe amounts of rice and sake, the traditional alcoholic beverage.
