The formula to convert Celsius to Fahrenheit is $F = \frac{9}{5}C + 32$, but since we are looking for a change in temperature, we only need to convert the change in temperature, not the absolute temperature. Therefore, the conversion factor of $\frac{9}{5}$ is used directly on the change in Celsius. So, $15°C \times \frac{9}{5} = 27°F$.
