Cold enough to freeze your nuts

I don’t know if folks knew this, but Google supposedly was meant to make life easier with maths, so you could feed in arithmetic into the search box and it would work it out.
Um, not really. Trying to convert temperatures just now was not easy. I have to type things in full: e.g. -6 degrees Celsius in Fahrenheit and not –6°C in °F (it didn’t like that) or –6°C in Fahrenheit. It is quicker reaching for a conversion calculator, or, if you remember the formula in your head, to do it that way.
I am not even that sure if people can spell Celsius and Fahrenheit.
I read on another Vox blog that it feels like –30°F in Chicago today, with the wind chill presumably. That’s –34°C in new money. It is a temperature that I find unfathomable as it never gets that cold here unless you head down to Antarctica.

I only dislike the cold when it's very windy (like it is currently in Chicago)
When I was in Bangkok in September of 2006, I found that I had to do my sightseeing either early morning or in the afternoon. Being out and about between 12-3 just wiped me out completely.
Why can't the US just adopt a sensible system of measures and save us the conversion hassle? :-)
