ok guys i give another try
you can cool water beneath 0°C or 32degrees farhenheit without freezing it. At this time -38°C ( -36.4 F according to the formula ) is the coldest sientists can get water before it freezes. Mr Farhenheit defined 0 degrees F as the coldest you can cool water before it freezes. But when he lived, one did not have cooled water that far ( obviously it was before

). 0 F was -17.77°C.
What a scale needs to be accurate is good marker points that are constant and can be reproduced. Thats not the case for the F scale
now its time to chill and forget about it
If you dont believe it ... well ... i wont care
