I used a generic unit conversion app that has a specific function for F-to-C conversion. That takes a minute or so to start, enter the numbers, etc. I could have read tens of paragraphs of text in that time.

I agree I'm being a bit harsh here, coming out of the blue on a random comment. But in general I'm very irritated that using non-metric units in an international forum is still a thing. The onus should be on the Americans in their communication, not on others.

The UK and Canada have converted, or are in transition. It takes a generation or maybe two, but I'm certain it's worth the trouble.
