Example Celsius and fahrenheit scales of temperature.Obtain the relation between celsius and fahrenheit scales of temperature celsius (Centigrade)scale of temperature.

Explanation

Celsius (centigrade) scale of temperature:In centigrade scale of temperature lower fixed point freezing point of water at one atmosphere pressure , as `0^(@) C`. The upper limit is boiling point of water at 1 atm pressure , as `100^(@)C`.
The interval between lower limit and upper limit `[100-0100]` is divided into 100 equal parts and each part is called `1^(@)`.
Fahrenheit scale of temperature : In Fahrenheit scale, the lower fixed point is freezing point of water at one atmosphere pressure ,as `32^(@) F.` The upper fixed point is boiling point of water at 1 atm pressure , as `212^(@)F`.
The interval between upper dixed point and lower fixed point `(212-32=180)` is divided into 180 equal and each part is called `1^(@)F`.
Relation between Fahrenheit and Celsius scale of temperature : In both scales, lower limit and upper limit same. The only change is in numerical values of lower and upper limits.
In Fahrenheit lower limit =32, upper limit =212, difference of limits =180 In Celsius scale lower limit =0 , upper limit =100, difference of limit =100
`(l_(F)-32)/(180)=(l_(c))/(100) (or) (9)/(5) C=F-32 (or) 1.8 C= F -32`
C= Temperature in Celsius scale .
F= Temperature in Fehrenheit scale .
