# Conversion of Temperature

In conversion of temperature from one scale into another the given temperature in °C we can convert it into °F and also the temperature in °F we can convert it into °C.

The rules which are used in this conversion are given below:

1. When the temperature is given in degree Celsius:

Step I: Multiply the given temperature in degree by 9

Step II: The product we obtained from step I divide it by 5.

Step III: Atlast add 32 with the quotient we obtained from step II to get the temperature in degree Fahrenheit.

2. When the temperature is given in degree Fahrenheit:

Step I: Subtract 32 from the given temperature in degree

Step II: The difference we obtained from step I multiply it by 5.

Step III: Atlast the product we obtained from step II divide it by 9 to get the temperature in degree Celsius.

Solved examples to convert the temperature from one scale into another:

1. Convert into degree Fahrenheit:

(i) 45° C

The temperature is given in 45° C.

To convert into degree Fahrenheit first multiply 45 by 9 and we get 405.

Then, divide 405 by 5 we get 81.

Atlast we need to add 32 and 81 we get 113.

Therefore, 45° C = 113° F

(ii) 100° C

The temperature is given in 100° C. Now to convert into degree Fahrenheit first multiply 100 by 9 we get 900 then, divide 900 by 5 we get 180. Atlast we need to add 32 and 180 then we get 212.

Therefore, 100° C = 212° F

(iii) 50° C

Therefore, 50° C = 122° F

2. Convert into degree Celsius:

(i) 98.4° F

The temperature is given in 98.4° F.

To convert into degree Celsius first we need to subtract 32 from 98.4 and we get 66.4.

Then, multiply 66.4 by 5 we get 332.

Atlast divide 332 by 9 and we get 36.9.

Therefore, 98.40° F = 36.9° C

(ii) 112° F

The temperature is given in 112° F. Now to convert into degree Celsius first we need to subtract 32 from 112 and we get 80 then, multiply 80 by 5 we get 400. Atlast divide 400 by 9 and we get 44.4.

Therefore, 112° F = 44.4° C

(iii) 212° F

Therefore, 212° F = 100° C

Now let us understand:

On the Celsius Scale            On the Fahrenheit Scale

Water freezes at                            0° C                                    32° F

Water boils at                             100° C                                  212° F

Normal body temperature                37° C                                 98.6° F
