It’s confusing, but there are two different units: “oz” (ounces) and “fl oz” (fluid ounces). Ounces are a unit of weight and fluid ounces are a unit of volume. But it’s not always written explicitly as “fl oz”, sometimes it’s shortened to just “oz” and you get from context they mean the fluid ones.
So 16 oz in that context means 16 fl oz, which is about 473 ml.
For water, they’re actually equivalent, just like grams and milliliters. As the old saying goes, “a pint’s a pound the world around, but mainly in the U.S. and Liberia.”
Yes, about 500ml. I was addressing the first part, where OP said “16 oz is approximately 500 g”. That means they converted weight (and were very generous in the approximation, since the result is about 453g). And then converted weight to volume, since water density is about 1g/ml.

They’re not equivalent. 1 g of water is 1 ml. But 1 oz is 28.3 g and 1 fl oz is 29.6 ml.
And not in the UK
So “about 500ml” like OP stated
