How to use this ml to oz
- 1Enter your volume in milliliters.
- 2The converter shows US fluid ounces, cups, and tablespoons instantly.
- 3For beverages, common bottle sizes: 250 ml = 8.45 fl oz, 330 ml = 11.16 fl oz, 500 ml = 16.91 fl oz, 750 ml = 25.36 fl oz (wine bottle), 1,000 ml = 33.81 fl oz.
- 4For medicine dosing, 5 ml = 1 teaspoon, 15 ml = 1 tablespoon, 30 ml = approximately 1 fl oz.
- 5For cooking, the cups output shows how many US cups the volume represents.
- 6This calculator uses US fluid ounces (29.57 ml) — UK fluid ounces are 28.41 ml, about 4% less.
How it's calculated
fl oz = ml ÷ 29.5735. 1 US fl oz = 29.5735 ml.
About the ml to oz
Milliliters and fluid ounces are the small-volume measurement units that appear in cooking recipes, pharmaceutical dosing, beverage labeling, and bar measurements. The conversion factor — 1 US fluid ounce = 29.5735 ml — bridges the metric and imperial volume systems that divide the world into two camps.
The most critical distinction in volume conversion is between the US fluid ounce (29.5735 ml) and the UK/Imperial fluid ounce (28.4131 ml). These differ by approximately 4%, which is significant in precise contexts. A can of US soda labeled 12 fl oz contains 354.9 ml by US measure; the same label on a UK product would contain 341 ml. Medical dosing instructions specify which fluid ounce they reference, and misidentifying the standard could lead to dosing errors. This calculator uses the US fluid ounce throughout.
Cooking and baking require ml-to-fl-oz conversion when adapting between US recipes (which use fl oz and cups) and metric recipes (which use ml and liters). Common reference points: 30 ml ≈ 1 fl oz, 240 ml = 1 cup = 8 fl oz, 480 ml = 1 pint = 16 fl oz, 960 ml = 1 quart = 32 fl oz. For liquid ingredients in baking (milk, water, oil), volume measurement in either ml or fl oz is appropriate; for dry ingredients, weight in grams is more precise.
Pharmaceutical dosing uses milliliters as the universal standard for liquid medications. The standard medicine spoon measurements are: 5 ml = 1 teaspoon, 10 ml = 2 teaspoons = 2/3 tablespoon, 15 ml = 1 tablespoon, 30 ml ≈ 1 fl oz. When converting between the two systems for medical context, precision is important — always use the measuring device provided with the medication rather than kitchen spoons, which don't measure consistent volumes.
The beverage industry creates significant ml-to-fl-oz conversion needs for international producers, importers, and retailers. Wine bottles worldwide are 750 ml (25.36 fl oz); beer cans are 330 ml (11.16 fl oz) or 355 ml (12 fl oz) in the US; spirits bottles are typically 700 ml (23.67 fl oz) or 750 ml (25.36 fl oz). Regulatory labeling requirements vary by country, with the US requiring fl oz labels and most other countries requiring ml. Understanding both units is essential for anyone importing or exporting beverages.
Frequently asked questions
How many fl oz is 500 ml?
500 ml ÷ 29.5735 = 16.91 US fl oz. A 500 ml bottle is just under a US pint (16 fl oz = 473 ml). Common ml to fl oz: 250 ml = 8.45 fl oz, 330 ml = 11.16 fl oz, 750 ml = 25.36 fl oz, 1 liter = 33.81 fl oz.
How many ml is 8 fl oz?
8 fl oz × 29.5735 = 236.6 ml — one US cup. This is why 1 US cup = 8 fl oz = 236.6 ml exactly.
What is the difference between US and UK fluid ounces?
The US fluid ounce = 29.5735 ml. The UK (imperial) fluid ounce = 28.4131 ml — approximately 4% smaller. A 16 fl oz US pint = 473 ml; a 20 fl oz UK pint (pub pint) = 568 ml. Always check which fluid ounce is referenced, especially on imported beverages and in medical instructions.
How many ml is a standard medicine tablespoon?
A standard medical tablespoon is exactly 15 ml. A teaspoon is 5 ml. These are defined metric volumes used universally in medicine — not the kitchen tablespoon or teaspoon, which may vary. Always use the measuring syringe or spoon included with liquid medications rather than kitchen utensils for accurate dosing.
How many ml is a shot of alcohol?
A standard US shot is 1.5 fl oz = 44.36 ml. A single UK measure is 25 ml (about 0.85 fl oz) in most English/Welsh pubs, or 35 ml in Scotland. Australia uses a standard drink of 10 ml of pure alcohol, which corresponds to about 30 ml of standard spirits. When following cocktail recipes, clarifying which fl oz or ml standard is being used avoids over- or under-pouring.
