Instead of dividing by 29.5735, just divide by 30. You'll be off by about 1.4%, which is negligible for cooking and daily use.

• 750 ml ÷ 30 = 25 oz (actual: 25.36)
• 200 ml ÷ 30 = 6.67 oz (actual: 6.76)

The "Multiply by 0.034" Method

For people who prefer multiplying: ml × 0.034 gives a decent estimate.

Frequently Asked Questions

How many ounces are in 750 ml?

750 ml equals 25.36 US fluid ounces or about 26.40 UK fluid ounces. A standard wine bottle is 750 ml, which is just over 25 US fl oz — roughly five 5-oz glasses of wine.
