Many scientific data are reported at 30 °C. What is this temperature in degrees Fahrenheit?

Question

Express the temperature in Fahrenheit to two significant digits.

Answer 1

To convert a temperature from degrees Celsius (°C) to degrees Fahrenheit (°F), you can use the formula:

\[ °F = (°C \times \frac{9}{5}) + 32 \]

For 30 °C, the conversion to Fahrenheit would be:

\[ °F = (30 \times \frac{9}{5}) + 32 \] \[ °F = (30 \times 1.8) + 32 \] \[ °F = 54 + 32 \] \[ °F = 86 \]

Thus, 30 °C is 86 °F.

Expressing this to two significant digits, the temperature is:

86 °F.
