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
