Converting from Fahrenheit to CelsiusFormula:
C = (F–32) · (5/9)Approximate version (to do in your head):
C = (F–30)/2
Converting from Celsius to Fahrenheit
F = C·9/5 + 32Approximately:
F = C·2 + 30
The same degrees in both systems?To get the answer, you have to solve the following equation:
x = (x–32) · (5/9)The answer is x = –40. Thus: –40°C is the same temperature as –40°F. Most of us can thus agree that that’s very cold.
