Celsius is a temperature scale where the freezing point of water is 0 degrees and the boiling point is 100 degrees. Used to known as centigrade until the mid of 20th century. The abbreviation is "oC".
Fahrenheit is a temperature scale where the freezing point of water is 32 fahrenheit degrees and the boiling point is 212 degrees (100 celsius to fahrenheit is 212). It is replaced by celsius scale as part of the metrication process but it is used in United States for all kinds of applications to measure the temperature. The abbreviation is "oF".
The celsius to fahrenheit conversion formula: Fahrenheit = Celsius * 1.8 + 32
It is because, if you compare the freezing and boiling points for each unit, there are 1.8 fahrenheit degrees for one celsius degree, i.e 212 (boiling point for oF) - 32 (freezing point for oF) / 100 (boiling point for oC)= 1.8
45 degrees celsius to fahrenheit is: 45 o
C = 45 * 1.8 + 32 = 113 o
