Question

On which degree the celsius and fahrenheit are equal with opposite sign

Answer 1

Heyyy buddy.. Here is your answer :)

We know °F=[°C×1.8] +32

Let the temperature be x. So we have x°F = -x°C

Now putting in the formula, we have

x = -1.8x+32

=> 2.8x = 32

=> x = 32/2.8 = 11.428571

So in Fahrenheit it is +11.428571°F and in Celsius it is -11.428571°C
