To convert degrees Celsius (°C) to degrees Fahrenheit (°F), you can use the formula:
\[ °F = (°C \times \frac{9}{5}) + 32 \]
For 30° C, the conversion would be:
\[ °F = (30 \times \frac{9}{5}) + 32 \]
\[ °F = (30 \times 1.8) + 32 \]
\[ °F = 54 + 32 \]
\[ °F = 86 \]
Therefore, 30° C is equal to 86° F.
