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.

      Fluid ounces measure volume, so analogous to liters. As opposed to ounces which measure weight, so analogous to newtons, although everyone uses kilos to measure weight in day to day life.

      There are also Troy ounces, which are for precious metals, but I honestly couldn’t say what those measure…

        You may want to reply directly to Mr_Blott as I’m not sure they’ll see your explanation unless they check back in on this thread.
