someone please help me i am at a loss to figure this question out. How did he come up with his temperature scale and why is freezing and boiling seperated into two seperate parts. why is this so significant?

thanks to everyone whoes answered this so far but all the info and sites u've given me so far aren't what i'm looking for. 180 is an important number and i need to figure out a good reason why. my teacher is making me.

First of all, Fahrenheit freezing point and boiling point are 32 and 212 respectively but this is because the basis of his temperature was taken from the Metric system of Celsius which when converted is exactly 0 and 100 degrees respectively.
Conversion of C --> F:
(0 x 9/5) + 32 = 32 Degrees Fahrenheit
(100 x 9/5) + 32 = 212 Degrees Fahrenheit
Secondly, the reason why its differential is 180 is because before basis of temperature were done by human comfort and not mercury.
From that study, It was necessary to calibrate the temperature to move exactly the same as that of mercury thermometer.
That is why Fahrenheit system was adjusted to 32 and 212 and just so happened to be 180 degrees apart.

I'm not realy for sure but 180 degrees is the opposite ends of boiling and freezing as two points on a line are 180 degrees apart from each other.

It seems to me that 0 degrees fahrenheit is the freezing point of sea water. The 180 equal parts is the difference between water's freezing point (32) and its boiling point (212.)

He wanted zero to be the coldest temperature he could get, and that was a mixture of salt and ice. Since there is no such thing as a hottest temperature, he decided that body temperature should be 100. He missed by a bit. And, that's all there is to it.

So, 28 - 32 = -4 * 5/9 = -2.22 or -2 degrees Celsius.
