How we got this
500 milliliters × 1 mL/mL = 500 mL
500 mL ÷ 29.5735295625 mL/fl oz = 16.9 US fl oz
1 US fl oz = 29.5735295625 mL (NIST). 1 UK fl oz = 28.4130625 mL (UK Weights and Measures Act 1985).
Density used: water, 1 g/mL. By definition close to 1 g/mL at room temperature. Source: NIST.
Also useful:
Divide milliliters by 29.5735 for US fluid ounces, or by 28.4131 for UK ones. For scale, 100 mL is about 3.4 US fl oz, 250 mL is about 8.5, and 500 mL is about 16.9, which is why a half-litre water bottle is labeled 16.9 oz.
Milliliters measure volume, so they convert to fluid ounces directly. A weight ounce needs an ingredient. 100 mL of water is 3.53 oz by weight, 100 mL of honey is about 5 oz, and 100 mL of flour is about 1.9 oz.

Formula
US fl oz = mL ÷ 29.5735295625mL = US fl oz × 29.5735295625UK fl oz = mL ÷ 28.4130625mL = UK fl oz × 28.4130625oz = mL × density (g/mL) ÷ 28.349523125

Questions
How many ounces is 500 mL?
16.91 US fl oz or 17.60 UK fl oz. By weight, 500 mL of water is 17.64 oz.
How many ounces is 100 mL?
3.38 US fl oz or 3.52 UK fl oz. That is the reason US carry-on liquid limits are written as 3.4 oz.
Is 250 mL one cup?
A metric cup is 250 mL. A US cup is 236.59 mL, so the metric cup is about 6% larger. That is fine for soup and noticeable in baking.
