- 4 c

$- 4 c$

Step 1

This is the conversion formula for Celsius to Fahrenheit, where

T_{F}

$T_{F}$ is temperature in Fahrenheit and

T_{C}

$T_{C}$ is temperature in Celsius.

T_{F} = \frac{9}{5} T_{C} + 32

$T_{F} = \frac{9}{5} T_{C} + 32$

Step 2

Substitute the Celsius temperature into the formula.

(\frac{9}{5} \cdot - 4 + 32) F

$(\frac{9}{5} \cdot - 4 + 32) F$

Step 3

Divide

9

$9$ by

5

$5$ .

(1.8 \cdot - 4 + 32) F

$(1.8 \cdot - 4 + 32) F$

Step 4

Multiply

1.8

$1.8$ by

- 4

$- 4$ .

(- 7.2 + 32) F

$(- 7.2 + 32) F$

Step 5

Add

- 7.2
