$e^{- 4} f$

Step 1

This is the conversion formula for Fahrenheit to Celsius, where $T_{F}$ is temperature in Fahrenheit and $T_{C}$ is temperature in Celsius.

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

Step 2

Substitute the Fahrenheit temperature into the formula.

$\frac{5}{9} (e^{- 4} - 32) C$

Step 3

Divide $5$ by $9$ .

$0.\overline{5} (e^{- 4} - 32) C$

Step 4

Replace $e$ with an approximation.

$0.\overline{5} ({2.71828182}^{- 4} - 32) C$

Step 5

Raise $2.71828182$ to the power of $- 4$ .

$0.\overline{5} (0.01831563 - 32) C$

Step 6

Subtract $32$ from $0.01831563$ .

$0.\overline{5} \cdot - 31.98168436 C$

Step 7

Multiply $0.\overline{5}$ by $- 31.98168436$ .

$- 17.76760242 C$
