The equivalent temperature on the Celsius scale is $-30^{\circ}~C$
We can convert $-22^{\circ}~F$ to its equivalent temperature on the Celsius scale. $C = \frac{5}{9}~(F-32)$ $C = \frac{5}{9}~(-22-32)$ $C = \frac{5}{9}~(-54)$ $C = -30$ The equivalent temperature on the Celsius scale is $-30^{\circ}~C$
