good point but ...
the formula isnt entirly correct its only an approach
This is what happened.
Mr Farhenheit defined the farhenheit scale by two marker points
1) 0 degrees was de coolest you can get water before it freezes
2) 100 degrees was his body-temp
Today people have succeeded to cool water more and more before it starts to freeze, yes thats true under special conditions (without changing preassure offcourse) you can get water below 0°C. But this means the farhenheit scale shifts every time they succeeded to cool down water even further.
Second, body temp changes all the time, its 37.5 °C on average but not all the time. How could you define what 100 degrees F should be :shrug:
this is not ''my point of view'' or my opinion this are facts
offcourse for everyday use the F-scale is usable
AND ... i dont want make a big deal off this, i only mentioned it
