500ml to 440ml?

Edit: the 440 on the right, is the last of a can that I bought in a four pack. The 500 on the left, is one of three I bought as singles.

Packaged Guinness comes in 440 milliliters. Single cans of Guinness come in 500 mL.

Apparently, that’s how Guinness does it here in Canada.

And apparently, I lazily avoided any attempt to research or apply any level of critical thinking before posting.

    I always thought it was because 440ml is a round number when you convert it from metric to medieval units (not a pint though, which is 568ml), but a quick google shows me there’s another reason:

    One reason for the popularity of the 440ml size is its convenience for calculating alcohol units. A 440ml can at 4.5% alcohol by volume (ABV) equates to exactly 2 units of alcohol, making it easier for consumers to track their alcohol consumption
