mL to oz Converter (750 mL in Ounces)

To convert mL to US fluid ounces, divide by 29.574. 750 mL is 25.36 fl oz, 500 mL is 16.91 fl oz and 100 mL is 3.38 fl oz. For UK (imperial) fluid ounces, divide by 28.413 instead. One US fluid ounce is 29.57 mL.

Convert milliliters to US or UK fluid ounces — plus liters, cups, tablespoons, teaspoons and 1.5 oz shots. Pick any unit on either side; the page link keeps your conversion.

How to use this converter

1. Enter the amount and choose its unit (mL is the default).
2. Choose the unit you want under "Convert to" — US fl oz for American recipes and labels, UK fl oz for older British recipes.
3. Read the headline result, and check the list below it for cups, tablespoons, teaspoons, pints and shots at the same time.
4. Share the link to keep the exact conversion.

How it's calculated

The US fluid ounce is defined from the US gallon: 1 gallon = 231 cubic inches = 3,785.411784 mL, and 1 gallon = 128 fluid ounces (NIST Handbook 44, Appendix C). The UK fluid ounce is 1/20 of the imperial pint of 568.26125 mL (UK Weights and Measures Act 1985, Schedule 1).

• US fl oz = mL ÷ 29.5735295625
• UK fl oz = mL ÷ 28.4130625
• mL = US fl oz × 29.5735

Other US kitchen units follow from the same table: 1 cup = 8 fl oz, 1 tablespoon = ½ fl oz, 1 teaspoon = ⅓ tablespoon, 1 pint = 16 fl oz, 1 quart = 32 fl oz.

Worked examples

1. A 750 mL bottle of wine

750 ÷ 29.5735 = 25.36 US fl oz. At 1.5 fl oz per shot, that is 16.9 shots; at NIAAA's 5 fl oz standard glass of 12% wine, 5.1 glasses.

2. Is my 120 mL bottle allowed in carry-on?

120 ÷ 29.5735 = 4.06 US fl oz. TSA's limit is 3.4 ounces (100 milliliters) per item, so a 120 mL bottle is over the limit (medications and infant nourishment are exempt).

3. A recipe asks for 250 mL of milk

250 ÷ 29.5735 = 8.45 US fl oz, or 1.06 US cups — just over 1 cup. In tablespoons that is 16.9.

Common bottle sizes in ounces

US federal rules set the bottle sizes ("standards of fill") that spirits and wine may be sold in. They include 50, 100, 187, 375, 700, 750, 1,000 and 1,750 mL for spirits (27 CFR 5.203) and 187, 375, 750, 1,000 and 1,500 mL for wine (27 CFR 4.72).

Standard drinks in mL

NIAAA defines a US standard drink by volume and strength. Each of these contains about 0.6 fl oz of pure alcohol:

• Beer: a 12 oz can at 5% alcohol by volume = 355 mL.
• Wine: a 5 oz glass at 12% = 148 mL.
• Spirits: a 1.5 oz shot at 40% = 44 mL.

So a 750 mL bottle of 12% wine holds about 5.1 standard glasses, and a 750 mL bottle of 40% spirits about 16.9 standard shots. Stronger drinks contain more alcohol per ounce, so these counts only hold at the stated strengths.

Travel-size liquids: 100 mL and 3.4 oz

TSA allows liquids, aerosols, gels, creams and pastes in carry-on bags in containers of 3.4 ounces (100 milliliters) or less per item, packed in one quart-sized bag per passenger. Medications and infant and child nourishment are exceptions. A container marked in mL passes if it is 100 mL or smaller; one marked in ounces passes at 3.4 oz or less. Common travel sizes convert as follows: 30 mL = 1.01 oz, 50 mL = 1.69 oz, 75 mL = 2.54 oz, 100 mL = 3.38 oz.

Kitchen measures: exact vs nutrition label

FDA nutrition labels use rounded metric equivalents (21 CFR 101.9(b)(5)(viii)). For cooking, the difference rarely matters; for scaling large batches, use the exact figure.

UK pints and fluid ounces

The imperial pint is 568.26 mL and holds 20 UK fl oz, against 16 fl oz in a US pint of 473.18 mL. The imperial fluid ounce is also slightly smaller than the US one (28.41 vs 29.57 mL). Draught beer and cider in the UK are still sold in pint-based measures; a 2011 order added the two-thirds pint (379 mL) to the lawful quantities alongside the half pint and pint.

Common mistakes

• Mixing up fluid ounces and ounces. A fluid ounce is volume; an ounce is weight. To turn a volume into a weight you need the density; the weight per gallon calculator does this for water, fuels and other liquids.
• Using US ounces for a UK recipe. Older British recipes use imperial fl oz and 20 oz pints. The error is about 4% per ounce but 20% per pint.
• Taking label values as exact. "1 cup (240 mL)" on a label is rounded; a US cup is 236.59 mL.
• Converting a rounded number again. If you round 750 mL to 25 oz and then convert back, you get 739 mL. Keep the original figure and convert once.
• Assuming 100 mL is exactly 3.4 oz. It is 3.38 oz. TSA's 3.4 oz figure is its own rounding of 100 mL.
