Which of the following is a correct relationship between Fahrenheit (°F) and Celsius (°C) degrees ?
Explanation
The relationship between the Fahrenheit (°F) and Celsius (°C) scales is based on the freezing and boiling points of water. In the Celsius scale, water freezes at 0°C and boils at 100°C (a range of 100 units). In the Fahrenheit scale, water freezes at 32°F and boils at 212°F (a range of 180 units).
The ratio of the scales is 180/100, which simplifies to 9/5. Therefore, the conversion formula is:
°F = (9/5 × °C) + 32
Option A is incorrect because it incorrectly applies the ratio to Fahrenheit to find Celsius. Options B and D are incorrect because 273.15 is the value used for converting between Celsius and Kelvin (K = °C + 273.15), representing absolute zero.
