Q. Which of the following is a correct relationship between Fahrenheit (°F) and Celsius (°C) degrees?
a) °C = 9/5 °F + 32
b) °F = °C – 273.15
c) °F = 9/5 °C + 32
d) °C = °F – 273.15
Question from UPPSC Prelims 2024
Correct Answer: c) °F = 9/5 °C + 32
Explanation:
The relationship between Fahrenheit (°F) and Celsius (°C) is derived from their respective temperature scales. The formula to convert Celsius to Fahrenheit is:
°F = (9/5 × °C) + 32
This means that to convert a temperature from Celsius to Fahrenheit, you multiply the Celsius temperature by 9/5 and then add 32. This formula is based on the fact that the freezing point of water is 0°C (32°F) and the boiling point of water is 100°C (212°F), with a proportional relationship between the two scales.
Correct Answer: c) °F = 9/5 °C + 32
