If you’ve ever looked at a bottle of wine, liquor, olive oil, or another beverage, you may have wondered how many oz in 750 mL. This is one of the most common volume conversions because 750 milliliters is a standard bottle size used around the world.
The exact answer depends on whether you’re using US fluid ounces or Imperial (UK) fluid ounces.
- 750 mL = 25.36 US fluid ounces
- 750 mL = 26.40 Imperial fluid ounces
Since the United States uses US fluid ounces, you’ll most often see 750 mL rounded to 25.4 oz.
This guide explains the conversion, provides formulas, charts, and practical examples for everyday use.

How to Convert 750 mL to Ounces
The conversion depends on the ounce system you use.
US Fluid Ounces
Formula:
US fl oz = mL ÷ 29.5735
Calculation:
750 ÷ 29.5735 = 25.36 US fl oz
Imperial Fluid Ounces
Formula:
Imperial fl oz = mL ÷ 28.4131
Calculation:
750 ÷ 28.4131 = 26.40 Imperial fl oz
Why Are There Two Types of Fluid Ounces?

| Measurement | Milliliters |
|---|---|
| US Fluid Ounce | 29.5735 mL |
| Imperial Fluid Ounce | 28.4131 mL |
Because the US fluid ounce is slightly larger, the number of ounces in 750 mL differs between the two systems.
