This is a shortcut to convert Fahrenheit to Celsius and vice versa.
The answer you will get will not be an exact one, but it will give you an idea of the temperature you are looking at.
Fahrenheit to Celsius:
Take 30 away from the Fahrenheit, then divide the answer by two. This is your answer in Celsius.
74 Fahrenheit – 30 = 44. Then divide by two, 22 Celsius.
so 74 Fahrenheit = 22 Celsius.
Celsius to Fahrenheit just do the reverse:
Double it, then add 30.
30 Celsius double it, is 60, then add 30 is 90
30 Celsius = 90 Fahrenheit
Remember, the answer is not exact but it gives you a rough idea.
