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 milliliter (mL) is a unit of volume in the metric system.
It's equal to one-thousandth of a liter (0.001 L). The plural form is milliliters.
A milliliter is the same as one cubic centimeter (1 mL = 1 cm3).
This direct relationship makes converting between liquid volume and cubic measurements incredibly simple.
This is why vehicle engine sizes are often listed in both cubic centimeters (cc) and liters.
For example, a 1500 cc engine is the same as a 1.5-liter engine.
For most practical purposes, one milliliter of water at its densest has a mass of about one gram.
This simple one-to-one relationship makes the metric system very logical for science and cooking, where water is a common ingredient.
Although the official definition of the gram has been updated, this easy approximation remains widely used in many fields.
The milliliter (mL) is a key unit for measuring small amounts of liquid in many different fields.
You can find it everywhere, from kitchens to laboratories.
