The Fahrenheit to Celsius conversion factor 5/9, comes after dividing 100 by 180. That is the range between the ice point in the Celsius and Fahrenheit scale. A simpler way of calculating this is as follows: We know that 9/5 = 1.8 = (2.0 - 0.2) = 2(1 - 0.1). This means that if you have to convert degree Celsius to Fahrenheit then you need to double the given ºC value, subtract 10%, and add 32 to it. Let's understand this by an example:
Convert 344 ºC to ºF by the above shortcut.
As mentioned above, 344 ºC = Double (ºC value) - 0.1(subtract 10%) + 32 = 2(344) - 0.1 (2) (344) + 32 = 651.2 ºF
What is the common point to both Celsius and Fahrenheit scales? Well, the point -40 ºC is common to both, and so we can derive some more alternative Fahrenheit conversion to Celsius conversion formulae that are as follows:
ºC = (ºF + 40º) 5/9 - 40º
ºF = (ºC + 40º) 9/5 - 40º
For example, 150 ºF = ?ºC, ºC = (150 + 40) 5/9 - 40 = 65.56 ºC (approximately)
The conversion from Celsius to Fahrenheit or vice versa just involves transferring the variables on the left and right side of the equation and putting the given values. Have fun studying them!
