What is a Fluid Ounce?
A fluid ounce is a unit that is used to measure liquids, like water, milk, or juice. It tells you how much space a liquid takes up, not how heavy it is. So when you see “fluid ounce” (sometimes written as fl. oz.), think of how much liquid is inside a cup or bottle. One fluid ounce is a small amount, about the size of two tablespoons of water.
What is a Cup?
A cup is another way to measure liquids and sometimes dry ingredients in cooking. It is a bigger unit than a fluid ounce. We often use cups in recipes to measure things like flour or milk and sometimes oil. For example, if a recipe says “1 cup of milk,” you could also measure that using several fluid ounces, because both cups and fluid ounces measure volume.
What’s the Difference Between Imperial, Metric, and US Customary?
This is where it gets a little tricky, because different countries use different units/systems to measure things.
US Customary System is used mainly in the United States.
In this system 1 cup equals 8 fluid ounces which equals 29.57 milliliters.
Imperial System is used in the United Kingdom and some older British recipes.
Imperial system is very old and rarely used now a days. In this system 1 cup is about 10 fluid ounces which equals 28.41 milliliters.
Metric System is used in most countries around the world.
This system is very simple and measurements are based in milliliters (mL) and liters.
- A metric cup = 250 milliliters
- No “fluid ounces” – they only use mL instead
Conversion Formulas
US Fluid Ounces (fl oz) to Cups Conversion
- 1 US fl oz = 29.5735 ml
- 1 US Cup = 236.588 ml
- 1 Cups (US) = 236.588 ÷ 29.5735 ( ≈ 8 )
\( \text{Cups (US)} = \frac{\text{Fluid Ounces (US)}}{8} \)
UK/Imperial Fluid Ounces (fl oz) to Cups Conversion
- 1 Imperial fl oz = 28.4131 ml
- 1 Imperial Cup = 284.131 ml
- 1 Cups (Imperial) = 28.4131 ÷ 284.131 ( ≈ 10 )
\( \text{1 Cups (Imperial)} = \frac{\text{Fluid Ounces (UK)}}{10} \)
Metric Cups (Used Worldwide)
- 1 Metric Cup = 250 ml
US fl oz to Metric cups:
- 1 Cups = US fl oz × 29.57 / 250ml
Imperial fl oz to Metric cups:
- 1 Cups = Imperial fl oz × 28.41 / 250ml
