A fluid ounce (fl oz) is a common unit used to measure volume in the imperial and US customary systems.
It tells you how much space a liquid takes up.
This is a common point of confusion: no, they are not the same!
The US fluid ounce is slightly larger than the UK (Imperial) fluid ounce. This slight difference is crucial to remember for recipes and measurements, especially when converting between systems.
The word "ounce" can be tricky because it measures two different things:
A fluid ounce (fl oz) measures volume (how much space something occupies).
An ounce (oz) measures weight (how heavy something is).
Think of it like this: a fluid ounce tells you the size of a container, while a regular ounce tells you how heavy its contents are.
For example, one fluid ounce of honey is much heavier than one fluid ounce of cooking oil because honey has a higher density.
The idea of the fluid ounce has a practical history.
In the British Imperial system, it was initially defined as the volume taken up by one ounce of water at a specific temperature.
This simple link between weight and volume made it a convenient and intuitive unit for measuring everyday liquids like water, wine, and ale for centuries.
A cup is a unit of volume measurement equal to 8 fluid ounces (fl oz).
It's one of the most common measurements used in recipes for cooking and baking, especially in the United States.
While they share the same name, not all cups are created equal.
A US customary cup is defined as 8 US fluid ounces (approximately 237 milliliters).
However, the metric cup used in countries like Australia, Canada, and New Zealand is standardized to 250 milliliters.
This slight difference is crucial to remember when following international recipes to ensure the correct ingredient proportions.

The name of the measurement isn't a coincidence. Before standardized units became common, recipes relied on informal measurements using everyday kitchenware.
The "cup" literally referred to the volume of a standard teacup. Over time, this was standardized into the precise unit we use today.
Although the unit of volume (8 fl oz) remains the same, the tools used to measure dry and liquid ingredients differ for a reason.
Using the wrong type can lead to inaccurate measurements.
