I just used kagi to search for the conversion, and thought the long decimal was funny.

But now that I think of it, does Canada make it's own 4 L jugs so they can be accurately advertised or do they just use the US 1 gal jugs and call it a 4 L out of convenience but then write in fine print on the bottom that it's actually 3.79 L?

Unless that is actually a 4L jug of vodka, couldn't someone sue for misrepresenting the amount of product being sold?

Someone's liquid here is probably not precise. And I'm going to guess it's the one claiming to be a larger volume with an additional manufacturing cost.
