Here's a little trick to estimate the temp in from Celcius to Fahrenheit. Just multiply it by 2 and add 32.If you want to go from Fahrenheit to Celcius the subtract 32 and the divide by 2.So for my example 4 F - 32 = -28 / 2 = -14 C. That's cold in PA. Wow saskbucks, you got guts or are nuts!
I think alot of you guys are talking wind chill temps and not actual air temps throwing out -20s and -30s. There's a big difference there.
