Question

At what temperature do celcius and fahreinheit scale show same reading

Answer 1

AnSwer :

Celsius and Fahrenheit scales are related by the equation.

$\mapsto\sf{\dfrac{C}{5} = \dfrac{5 - 32}{9}}$

Now, putting F = C, we get :

$\mapsto\sf{\dfrac{C}{5} = \dfrac{C - 32}{9}}$

$\rightarrow\sf{9\:C = 5\:C - 160}$

$\rightarrow\sf{4\:C = 160}$

◑ -40°C

※ Hence, at -40°C, Celsius and Fahrenheit scales have the same reading.
