## How many Ounces is 21 ML?

The answer to the question how many ounces is 21 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, 21 ml to oz is:

• 0.71 oz for United States customary fluid ounces
• 0.74 oz for Imperial fluid ounces = Canadian liquid ounces = UK liquid oz

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.
