To convert from degrees Celsius (°C) to degrees Fahrenheit (°F), you can use the formula:
\[ °F = (°C \times \frac{9}{5}) + 32 \]
In this case, you want to convert -79°C to °F.
Using the formula:
\[ °F = (-79 \times \frac{9}{5}) + 32 \]
Calculating it step by step:
-
Multiply -79 by \( \frac{9}{5} \): \[ -79 \times \frac{9}{5} = -79 \times 1.8 = -142.2 \]
-
Then add 32: \[ -142.2 + 32 = -110.2 \]
So, -79°C is equal to -110.2°F.
The final answer is:
The temperature is -110.2 degrees Fahrenheit.
