What is a fluid ounce?

A fluid ounce, despite the name, is not a liquid but a measurement unit. Commonly used in the imperial system, it is particularly useful to indicate everyday quantities of liquids—being good where milliliters and liters are respectively too small or too big.

Ounces are abbreviated in fl oz, or fl. oz.. There are two widespread units with the same name, but they differ in their value:

  • The British Imperial fluid ounce; and
  • The United States Customary fluid ounce.

Be careful, and remember to be sure which one you are using!

⚠️ Remember not to mistake the fluid ounce with the ounce, the measurement unit of mass!

An imperial fluid ounce is defined in terms of the imperial gallon:

1 fl oz=1160 gal1\ \text{fl oz} = \frac{1}{160}\ \text{gal}

While the US fluid ounce is defined using the US liquid gallon:

1 fl oz=1128 gal1\ \text{fl oz} = \frac{1}{128}\ \text{gal}

Let's check how to convert from ounces to milliliters: jump with us to the metric system!

How do you convert ounces to milliliters?

We need two conversions for the two different types of fluid ounces.

The conversion for the imperial fluid ounces is:

1 fl oz=28.4 ml 1\ \text{fl oz} = 28.4\ \text{ml}

While the **US fluid ounce$$ follows a slightly different conversion:

1 fl oz=29.6 ml1\ \text{fl oz} = 29.6\ \text{ml}

The difference between the two is slightly more than 44%: in everyday life, it's not relevant—your cake will be delicious anyway. However, it is fundamental to be sure of the units you are working with when it comes to measurements that require better accuracy.

Misunderstanding on the topic caused, over the years, millions of dollars in damages!

Depends on the size of the glass!
