To mL: multiply by 284.131. To US cups: multiply by 1.201. To liters: multiply by 0.284131.
1 UK cup = 10 UK fl oz = 1/2 UK pint = 284.131 mL ≈ 1.2 US cups.
For example, 1 Cup (UK) (cup (UK)) = 2.841306e-19 Exaliter (EL).

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.
To mL: multiply by 284.131. To US cups: multiply by 1.201. To liters: multiply by 0.284131.
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 exaliter is a unit of volume equal to 10¹⁸ liters, or one million cubic kilometers.
1 EL = 10¹⁸ L = 10¹⁵ m³ = 10⁶ km³ = 1,000 PL.
To liters: multiply by 10¹⁸. To km³: multiply by 10⁶. To petaliters: multiply by 1,000.
No practical applications — this scale exists only for astronomical and theoretical comparisons.
All the water on Earth (oceans, ice, groundwater, lakes, rivers, atmosphere) totals about 1.386 EL.
Almost never encountered, so mistakes are rare. The main risk is confusion with other 'E' prefixes (e.g., eV in energy).
Think of the exaliter as the 'planet volume' unit. Earth's oceans ≈ 1.335 EL. Prefix: exa = 10¹⁸ = quintillion.
