How to convert milliliters to US fluid ounces
1 mL ≈ 0.033814 fl oz (US)
1 US fluid ounce = 1/128 US gallon = 29.5735295625 mL exactly (NIST Handbook 44), so 1 mL = about 0.033814 US fl oz. An imperial fluid ounce is 28.4130625 mL.
Examples
- 100 mL = 3.3814023 fl oz (US): The TSA carry-on limit per liquid container (TSA)
- 750 mL = 25.360517 fl oz (US): A wine bottle at a US authorized standard of fill (eCFR (U.S. Government))
- 25 mL = 0.84535057 fl oz (US): One of the two legal UK pub spirits measures (GOV.UK)

Common mistakes
- Fluid ounces (fl oz) measure volume; ounces (oz) on a scale measure weight. They only line up for liquids close to water's density.
- A US fluid ounce is about 4% larger than an imperial fluid ounce, so UK and US answers differ.
