# Temperature (Celsius and Fahrenheit)

is equal to . Similarly,  is equal to .

Therefore, conversion of Celsius to Fahrenheit Formula can be written as: F = mC + a

Since at  the value is , therefore a = 32. and

212 = m100+32à m = 180/100 = 9/5

Therefore, formula to convert Celsius to Fahrenheit is:

F = (C x 9/5) + 32

Rearranging F and C give formula to convert Fahrenheit to Celsius:

C = (F – 32) x 5/9

Both equations are useful for conversion of Celsius to Fahrenheit and Fahrenheit to Celsius. If we know the value of temperature in degree Fahrenheit and want to calculate value in degree Celsius than equation C = (F – 32) x 5/9 can be used. Similarly, if we know the value of temperature in degree Celsius and want to calculate value in degree Fahrenheit than equation C = (F – 32) x 5/9 can be used F = (C x 9/5) + 32.

The city picked for finding its record high temperature and record low temperature is London. The record high temperature ((June, July and August)) and record low temperature (December) is given below in degree Celsius.

Record High Temperature: 32

Record Low Temperature:  -17

Converting, record high temperature and record low temperature from degree Celsius to degree Fahrenheit.

Record High Temperature: F = (C x 9/5) + 32 = (32 x 9/5) + 32 = 89.6

Record Low Temperature:  F = (C x 9/5) + 32 = (-17 x 9/5) + 32 = 1.4
