> I have no idea how many freedom fries units that is.

Kind of a bad attempt at humor? Imperial units is fine.

Imperialist here. Freedom fries was funny.

Had to add metric to an imperial unit application since it is to be sold internationally. I live in a Fahrenheit country so I set my phone, computer, and car to Celsius to learn how the the temperatures readings feel.

I 100% agree, "Freedom Fries Units" is quite fitting.

Turns out I prefer Celsius over Fahrenheit in day to day usage.

The US doesn't use Imperial units. It uses US customary units, which are different from Imperial in several significant ways, because the Imperial system evolved after the US split from the British Empire.

Also interestingly, US customary units are defined in terms of metric. So in a sense, the US does use the metric system.

I often correct people regarding the US not using Imperial as well but to be fair the only significant difference these days is in fluid measurements. Weight and length measurements were standardised between US customary and Imperial back in the 1950s
