How many Ounces is 15 ML?

The answer to the question how many ounces is 15 ml depends on the volume (oz) unit under consideration:
  • 29.5735295625 ml = 1 US customary fluid ounce
  • 28.4130625 ml = 1 Imperial fluid ounce = 1 UK fluid ounce = 1 Canadian fluid ounce
  • 30 ml = 1 US nutrition labelling fluid ounce
Thus, 15 milliliters to ounces is:
  • 0.51 oz for United States customary fluid ounces
  • 0.53 oz for Imperial fluid ounces = Canadian liquid ounces = UK liquid oz
  • 0.5 oz for United States nutrition fluid ounces
Except for the food labelling ounce in the US, which is defined as 30 ml, the volume unit fl oz is derived from the gallon, 1 ⁄ 160 imperial gallons in the United Kingdom, and 1 ⁄ 128 gallons in the United States.

Convert 15 ML to OZ

Now let’s look at how to convert the volume.

In the UK and CA, there is only one fluid ounce, so changing ml to oz UK or ml to fl oz CA is a no-brainer.

Simply divide 15 by 28.4130625 using the formula [oz] = 15 / 28.4130625.

For United States customary fl oz divide the amount of 15 milliliters by 29.5735295625 to obtain the equivalent in ounces applying the formula [oz] = 15 / 29.5735295625.

And in the case of US food ounces just divide the volume in ml by 30 to get the volume in fluid ounces: [oz] = 15 / 30.

If you don’t know which type of US ounces you have, then note that the difference between ml US customary oz and US food oz is only about 4 %.
