How to convert ounces to milliliters

milliliters = fluid ounces × 29.5735

Example: 12 fl oz × 29.5735 = 354.9 ml.

Convert ounces to milliliters (oz to ml) instantly. See a chart from 1/2 to 128 ounces, get the exact formula and compare US and UK sizes. Free and exact.
On the scale, 1 fluid ounce lines up with 29.57 milliliters; read any other amount straight across.

Multiply US fluid ounces by 29.57 to get milliliters (millilitres). Multiplying by 30 gives a fast estimate that runs slightly high, which is fine for a drink but not for a cake batter.

A 6 fl oz glass of juice holds 177.4 ml, and a 16 fl oz jar holds 473.2 ml. A full 64 fl oz jug comes to 1,893 ml, which reads better as 1.893 L.

These conversions apply to fluid ounces only. If a label shows ounces of weight, such as a jar of honey or a bag of rice, the milliliters depend on the food.

US vs UK fluid ounces

British recipes that give fluid ounces mean the imperial size of 28.41 ml. So 10 imp fl oz is 284.1 ml, while 10 fl oz in a US recipe is 295.7 ml.

The gap is small for a splash of milk but grows with the amount. Check where a recipe comes from before you convert a pint or more.

Converting cocktail measures to milliliters

Cocktail recipes written in the US give ounces, but a jigger bought elsewhere may be marked only in milliliters. These pours convert like this:

  • 1/4 fl oz is 7.393 ml.
  • 1/2 fl oz is 14.79 ml.
  • 3/4 fl oz is 22.18 ml.
  • 1 1/2 fl oz is 44.36 ml.

If your jigger has only ml lines, round each pour to the nearest line. Keeping the ratios between ingredients steady matters more than hitting every milliliter. To turn a metric recipe back into ounces, use the milliliters to ounces converter.

Ounces and milliliters: questions

Is 1 oz the same as 30 ml?

Close, but not exactly: one US fluid ounce holds 29.57 ml. The round 30 ml comes from US nutrition labels, where FDA labeling rules set a fluid ounce at 30 ml. For drinks and cooking, the difference hardly matters.

Is 1 oz always 30 ml?

No. A US fluid ounce is just under 30 ml, an imperial fluid ounce is 28.41 ml, and an ounce of weight has no fixed volume at all. An ounce of water fills about 28.3 ml, but an ounce of all-purpose flour fills about 54 ml.

How much is 100 oz in liters?

100 fl oz is 2.957 L, or 2,957 ml. That is a little over three quarters of a US gallon, which holds 128 fl oz. A 3 L jug would hold it with room to spare.

How many ml are in 50 oz?

50 fl oz equals 1,479 ml, just under one and a half liters. A 1.5 L bottle holds slightly more than that. In US cups, it is 6 1/4 cups.

How many ml is 2 oz?

Two US fluid ounces are 59.15 ml, the same as 1/4 cup or 4 tablespoons. A metric jigger with a 60 ml line holds just a little more.
