473.18mL
16 fl oz × 29.5735 = 473.18 mL
One US fluid ounce equals 29.5735295625 millilitres — 29.57 mL rounded. To convert fluid ounces to millilitres, multiply the number of ounces by 29.5735 (US) or 28.4131 (UK imperial). To go the other way, divide the millilitres by the same constant.

How to convert ounces to millilitres
Fix the unit system first, then it is one multiplication. For US fluid ounces multiply by 29.5735; for UK (imperial) fluid ounces multiply by 28.4131. To reverse it, divide by the same number.
Worked example: 8 fl oz × 29.5735 = 236.59 mL. So a US cup is just under 237 mL, not the 250 mL of a metric cup.
US vs UK (imperial) fluid ounces in millilitres
The two ounces are different sizes: 1 US fl oz = 29.5735 mL, while 1 UK (imperial) fl oz = 28.4131 mL. The imperial ounce is about 4% smaller, so the same ounce figure always gives fewer millilitres under the UK system.
The gap grows with the amount. At 1 fl oz it is barely a millilitre; at 20 fl oz it is 22 mL — the difference between an imperial pint (568 mL) and 20 US ounces (591 mL). Match the system to where the recipe came from, and use the US / UK toggle above to compare.

How many mL is 8 oz?
8 US fl oz = 236.59 mL, the size of a US cup. A metric cup is 250 mL.
How many mL is a 16.9 oz bottle?
Exactly 500 mL — that is why the bottle is labelled 16.9 fl oz.
How many mL is 1 oz?
29.57 mL for a US fluid ounce, or 28.41 mL for a UK (imperial) one.
How many mL in a US pint?
16 US fl oz = 473.18 mL. A UK pint is 20 imperial ounces, or 568.26 mL.
How we calculate these conversions
Every result uses the internationally defined fluid-ounce values, not rounded shortcuts. One US fluid ounce = 29.5735295625 mL (the US gallon, 3.785411784 L, divided by 128), and one UK imperial fluid ounce = 28.4130625 mL (the imperial gallon, 4.54609 L, divided by 160). We keep full precision internally and round only the figure you see.
These definitions come from the national standards bodies that maintain them — the US NIST Office of Weights & Measures for US customary units, and the UK National Physical Laboratory for imperial units. The converter never mixes the two systems — pick US or UK and the matching constant is applied.
Frequently asked questions
How many mL is in 1 oz?
29.5735 mL for a US fluid ounce, and 28.4131 mL for a UK (imperial) fluid ounce.
How do I convert oz to mL?
Multiply the fluid ounces by 29.5735 for US ounces, or by 28.4131 for UK ounces.
How many oz is 100 mL?
100 mL = 3.38 US fluid ounces, or 3.52 UK fluid ounces — just over the 3.4 oz cabin-baggage liquid limit.
Is 8 oz 250 mL?
No. 8 US fl oz = 236.59 mL. A metric cup of 250 mL is slightly larger, about 8.45 fl oz.
How many mL is 500 mL in ounces?
500 mL = 16.91 US fluid ounces, exactly half a litre — the standard water-bottle size.
How many mL is 32 oz?
32 US fl oz = 946.35 mL, a US quart — just under a full litre.
Does this work for weight ounces?
No. Millilitres measure volume, so this converter takes fluid ounces only. Weight ounces convert to grams (1 oz ≈ 28.35 g).
Is a millilitre the same as a cubic centimetre?
Yes. 1 mL = 1 cm³ exactly, which is why medicine doses are written in either unit.
