About Fluid Ounce (UK) (fl oz (UK))
Definition
The UK fluid ounce is a unit of liquid volume equal to 1/160 of an imperial gallon, or approximately 28.413 milliliters.
Mathematical Relationship
1 UK fl oz = 1/20 UK pt = 1/160 UK gal ≈ 28.4131 mL. It is about 4% smaller than a US fluid ounce.
Conversion Formula
To mL: multiply by 28.4131. To US fl oz: multiply by 0.96076. To UK pints: divide by 20.
Practical Applications
Older UK recipes, some beverage labels in Commonwealth countries, and traditional pharmaceutical dosing.
Interesting Facts
Paradoxically, the UK fluid ounce is smaller than the US fluid ounce (28.41 vs. 29.57 mL), even though UK pints and gallons are larger.
Common Mistakes
Assuming UK and US fluid ounces are the same — they differ by about 4%. This seems small but accumulates in recipes.
Educational Tips
UK fl oz ≈ 28.4 mL, US fl oz ≈ 29.6 mL. The UK has more fl oz per pint (20) vs. US (16), but each UK fl oz is smaller.
About Milliliter (mL)
Definition
The milliliter is a unit of volume equal to one thousandth of a liter (10⁻³ L), exactly equal to one cubic centimeter.
Mathematical Relationship
1 mL = 10⁻³ L = 1 cm³ = 1 cc = 1,000 µL. There are 1,000 mL in one liter.
Conversion Formula
To liters: divide by 1,000. To fluid ounces (US): multiply by 0.033814. To teaspoons (US): multiply by 0.202884.
Practical Applications
Medicine dosing, cooking measurements, beverage volumes (e.g., 330 mL soda can), and cosmetic product sizing.
Interesting Facts
A standard soda can holds 330–355 mL. A shot glass holds about 44 mL. One mL of water weighs exactly 1 gram at 4 °C.
Common Mistakes
Confusing mL with mg (volume vs. mass). Also, 1 mL of oil or alcohol does NOT weigh 1 gram — only water does (at 4 °C).
Educational Tips
1 teaspoon ≈ 5 mL, 1 tablespoon ≈ 15 mL. These are the best kitchen anchors. A standard medicine syringe holds 5 mL.
