If a thermometer indicates 30 degrees Celsius, what's the temperature in degrees Fahrenheit?
A) 24°F
B) 86°F
C) 17°F
D) 54°F
Answer (2)
The problem requires converting Celsius to Fahrenheit.
The conversion formula is: F = 5 9 C + 32 .
Substitute C = 30 into the formula: F = 5 9 × 30 + 32 .
Calculate the Fahrenheit temperature: F = 86 . The final answer is 86
Explanation
Understanding the problem We are given a temperature in Celsius, which is 30 degrees, and we need to convert it to Fahrenheit.
Stating the conversion formula The formula to convert Celsius to Fahrenheit is: F = 5 9 C + 32 where F is the temperature in Fahrenheit and C is the temperature in Celsius.
Substituting the value Now, we substitute the given Celsius temperature, C = 30 , into the formula: F = 5 9 × 30 + 32
Calculating Fahrenheit Let's calculate the Fahrenheit temperature: F = 5 9 × 30 + 32 F = 5 270 + 32 F = 54 + 32 F = 86
Final Answer Therefore, 30 degrees Celsius is equal to 86 degrees Fahrenheit.
Examples
Temperature conversion is a common task in many real-world scenarios. For example, when traveling to a country that uses a different temperature scale, you need to convert temperatures to understand the weather forecast. Also, many scientific and engineering applications require converting between Celsius and Fahrenheit. Knowing how to convert between these scales allows you to interpret data and communicate effectively in various fields.
To convert 30 degrees Celsius to Fahrenheit, we use the formula F = 5 9 C + 32 . Substituting C = 30 results in F = 86 degrees Fahrenheit. The correct answer is B) 86°F.
