"Millilitres" is the internationally accepted spelling (used in the UK, Australia, Canada, and most of the world), while "milliliters" is the American English spelling. They refer to the exact same unit of volume — 1/1000 of a litre.
1 US fluid ounce equals 29.5735 millilitres. 1 Imperial (UK) fluid ounce equals 28.4131 millilitres.
250 mL ÷ 29.5735 = 8.4535 US fluid ounces, or 250 ÷ 28.4131 = 8.7988 Imperial fluid ounces.
The UK adopted the metric system for most measurements. Millilitres are the standard unit for measuring small volumes in cooking, medicine, and science throughout the Commonwealth and Europe.
A US cup = 236.588 mL (8 fl oz), a metric cup = 250 mL, and a UK cup = 284.131 mL (10 Imperial fl oz).
