The milliliters people look up most

100 mL = 3.3814 fl oz
The airline cabin liquid limit, which US security posts as 3.4 oz. They are the same rule in two units.
330 mL = 11.1586 fl oz
A European drinks can, against the US standard 12 fl oz can of 355 ml.
500 mL = 16.907 fl oz
A small water bottle, and just over a US pint - close enough that the two get confused on a shelf.
750 mL = 25.3605 fl oz
A wine bottle, which is why a case of twelve comes to almost exactly two US gallons.

How the ml to ounces calculation works

A US fluid ounce is 29.5735295625 milliliters:

US fluid ounces = milliliters ÷ 29.57353

A fluid ounce is a volume, not a weight. The ounce on a kitchen scale is 28.35 g and measures mass; this one measures space. They are close enough in the case of water to be confused constantly, and wrong for anything else — 100 ml of oil is 3.38 fl oz but weighs only 3.24 oz.

The imperial fluid ounce is different again, at 28.4131 ml — about 4% smaller than the US one, even though the imperial pint and gallon are larger. Britain divides its pint into 20 fluid ounces where America divides its into 16.

Familiar volumes:

  • 5 ml (a teaspoon) → 0.17 fl oz
  • 15 ml (a tablespoon) → 0.51 fl oz
  • 100 ml — the airline cabin liquid limit → 3.38 fl oz, which is why US security posts the rule as 3.4 oz
  • 330 ml (a European can) → 11.16 fl oz, against the US standard 12 fl oz can of 355 ml
  • 750 ml (a wine bottle) → 25.36 fl oz
  • 1,000 ml → 33.81 fl oz

The cabin-liquid case is worth reading carefully: the limits are the same rule stated in two systems, so a 100 ml bottle and a 3.4 oz bottle are the same container, and a US 3.5 oz bottle is over the European limit.

For rough work, divide millilitres by 30 — accurate to about 1.4%.

Frequently asked questions

Does a part-full bottle count for the 100 ml cabin rule?

No - the rule is about the container, not the contents. Security will refuse a 200 ml bottle holding 50 ml, because the limit applies to the stated capacity: 100 ml, which is the same rule American signage writes as 3.4 fl oz. Decant into a marked 100 ml bottle rather than relying on how much liquid is actually in the one you have.

Why does a British bar serve wine in 125, 175 and 250 ml?

Those are the quantities a licensed premises in Britain is permitted to sell wine by, so the list is set in law rather than by the glass - which is why a bar can offer 250 ml and not 200 ml. In US fluid ounces they are 4.23, 5.92 and 8.45. A 750 ml bottle therefore gives six of the small glasses or three of the large.

Is a 70 cl spirits bottle the same as a 750 ml one?

No. Spirits are bottled at 700 ml in the UK and most of Europe, written as 70 cl, and at 750 ml in the United States - a 50 ml difference, or 1.7 US fluid ounces. Wine is 750 ml in both. A bottle of the same brand bought abroad can therefore hold less than the one at home at an identical stated strength.
