If a thermometer indicates 30 degrees Celsius, what is the temperature in degrees Fahrenheit?

A. 24°F

B. 17°F

C. 86°F

D. 54°F

If a thermometer indicates 30 degrees Celsius, the temperature in degrees Fahrenheit is 86 °F.

Boiling water measures 100 degrees in Celsius, and 212 degrees in Fahrenheit. Freezing water measure 0 degrees in Celsius, and 32 degrees in Fahrenheit.

So, if you want to convert Celsius into Fahrenheit, you will need to:

Multiply by 180/100

Add 32

Let's convert 30 degrees Celsius into Fahrenheit.

30 180/100 = 54

54 + 32 = 86

Answer=C

The conversion formula between Celsius and Fahrenheit is:

°F = (9/5*°C) + 32

Based on the information given, we know that °C=30. So we can solve for °F.

°F = (9/5*°C) + 32

°F = (9/5*30) + 32

°F = (54) + 32

°F=86

30 Degrees Celcius is equivalent to 86 degrees Fahrenheit.
