The UK (imperial) cup is a unit of volume equal to 10 UK fluid ounces, or approximately 284.131 milliliters.
1 UK cup = 10 UK fl oz = 1/2 UK pint = 284.131 mL ≈ 1.2 US cups.

Older British cookbooks, some Commonwealth recipes (especially pre-metric era), and traditional baking.
The UK cup is 20% larger than the US cup. A recipe calling for 1 UK cup actually requires about 1.2 US cups.
Using a US cup measure for a UK recipe — the 20% difference can ruin baked goods. Check the recipe's origin.
UK kitchens rarely use cups now — most British recipes specify grams and mL. If you see 'cups' in a UK recipe, it's 284 mL.
The UK fluid ounce is a unit of liquid volume equal to 1/160 of an imperial gallon, or approximately 28.413 milliliters.
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.
To mL: multiply by 28.4131. To US fl oz: multiply by 0.96076. To UK pints: divide by 20.
Older UK recipes, some beverage labels in Commonwealth countries, and traditional pharmaceutical dosing.
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.
Assuming UK and US fluid ounces are the same — they differ by about 4%. This seems small but accumulates in recipes.
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.
