500ml to ounces

500ml converts to 16.91 US fluid ounces or 17.6 British Imperial fluid ounces. This conversion is for fluid ounces and not dry ounces.

The fluid ounce is used to measure volume, where-as the dry ounce is used to measure weight. So, if you're trying to measure the weight of a bottle of drink or an ingredient, you'll need to factor in the density of the substance in order to get a weight figure. For reference, a 500ml bottle of water weighs around 17.64 ounces (500g) and a 500ml bottle of milk weighs around 18.25 ounces.

You can, of course, use our converter at the top of this page to help you convert to dry ounces. Simply select 'Dry Ounces' in the dropdown menu. For help with gram conversions, you can use our ml and grams converter tool.

The US fluid ounce is larger than the British fluid ounce because the British quart is divided into 40 fluid ounces, whereas the US quart is divided into only 32 fluid ounces. 1

The formula for converting US fluid ounces to milliliters looks like this:

milliliters = US fluid ounces × 29.57353
