Question

In what temp does fahrenheit and celsius become same

Answer 1

Answer:

-40 °C

Step-by-step explanation:

Celsius and Fahrenheit are two temperature scales. The Fahrenheit and Celsius scales have one point at which they intersect. They are equal at -40 °C and -40 °F.

Answer 2

Answer:

$-40^{0}C (or) -40^{0}F(or)233K$

Step-by-step explanation:

$F=\frac{9}{5} C+32$       [F= temp. in fahrenheit  and C= temp. in celsius.]

Here, let F = C = x

Therefore,  $x = \frac{9}{5} x+32$

              => $\frac{4}{5}x=-32$

              => $x=-40^{0}C (or) -40^{0}F$

In kelvin scale, x = 273-40 = 233K
