What is the temperature at celcius and farenhiet are same .explain |
|
Answer» To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations. So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees. No they are not same |
