45.7°f = what in celsius
Is this the equation I should be using
C = °F-32/1.8
C= 45.7-32/1.8= 7.6
You can check that is correct by checking the "easy values". The freezing point of water is 0 C and 32F:
(32-32)/1.8= 0/1.8= 0 so that is correct.
The boiling point of water is 100 C and 212 F:
(212- 32)/1.8= 180/1.8= 100 so that is correct.
Since this is a "linear" equation and two points determine a line you know that is the correct formula for any F.
