If I say I have .473 liters of liquid how much is that?
That just seems like a strawman. What it boils down to is that when you convert from one system to another, conversions are not going to produce nice round numbers. There’s nothing special about pints that make them the authoritative drink. Why not just go for a nice, round half liter?
I think what you’re getting stuck on is the imperial system being the default for you instead of these both being human constructs.
