In Chicago, the winter ca quail, the degree of coagulation is strongly related to temperature (and wind). The problem is that indigenous peoples have their own unit of measure: the Fahrenheit.
The Fahrenheit was invented by a German physicist of the same name. He had to do things better than this measure in his life, like a family and having children. Because precision level, extracted from Wikipedia: " Fahrenheit decided to fix the zero of its scale as the lowest temperature he measured during the harsh winter of 1708 to 1709 in his hometown of Danzig. "
J'l'imagine well the guy out Fahrenheit his home one morning and exclaim: Cow! That quail this morning! we will say that it is zero. Ben bravo my rabbit, you're super precise as a boy ... Good short, after that, he invented a s is small scale and everything. And then there are countries like the USA who have found fun to use this measure.
Eric, Table! Yeah! Looks pushes you a little:
In the X-coordinate value x C Celsius us in orderly Fahrenheit F them. The blue curve C passes the F. The yellow curve C passes the ... C, but can especially see that when he does 40Celcius it does 40Fahrenheit (the two curves intersect).
I've put 4 other noteworthy values: the water freezes, the temperature of a house that respects the human body, and the human body at a boiling sea
And better to have typical values in mind Because the formula changes from F to C, I give it to you in a thousand: take 32 and multiply by 9 and divide by 5 ... Put your hat it will do you think TFW faster.
We see no other explanation.
