Answer
$-17.8^{\circ}~C$
Work Step by Step
$C = \frac{5}{9}(F-32)$
We can use this formula to convert from Fahrenheit to Celsius. It is given in the question that $F = 0$ since the temperature on the Fahrenheit scale is $0^{\circ}~F$.
$C = \frac{5}{9}(F-32)$
$C = \frac{5}{9}(0-32)$
$C = \frac{5}{9}(-32)$
$C = -17.8$
The temperature on the Celsius scale is $-17.8^{\circ}~C$
