Question

Convert $-40°F$ to the Celsius scale.

Answer 1

Step 1: We have

The given temperature $=-40°F$

Step 2: To convert the given temperature in $°C$

$\frac{C}{5}=\frac{F-32}{9}$

$\frac{C}{5}=\frac{-40-32}{9}$

$\frac{C}{5}=\frac{-72}{9}$

$\frac{C}{5}=-8$

So, $C=\left(-8\times 5\right)°C$

$C=-40°C$

Hence, the required temperature is $-40°C$.
