When converting millilitres to fluid ounces, 750 ml is equivalent to approximately 25.4 fluid ounces. Milliliters are part of the metric system, whereas ounces are part of the US and imperial systems of measurement.
750 ml is the most popular bottle size for both wine and spirits, though 1 L and 1.5 L are also available. Although the bottles are measured using the metric system, drink recipes in the United States are typically created using ounces. To determine how many drinks a bottle will yield, bartenders must convert to ounces.
A standard glass of wine contains 5 ounces, so a standard 750 ml bottle yields approximately five standard glasses. A standard mixed drink, such as vodka and tonic, contains 1.5 ounces of spirits, so a 750 ml bottle contains enough alcohol for approximately 17 mixed drinks.
