Which of the following shows the correct formula for converting temperature from degrees Celsius to degrees Fahrenheit?
A
F = (C + 32) / 1.8
B
F = (9/5)C + 32
C
F = C - 32
D
F = (5/9)C + 32
Verified step by step guidance1
Understand that the problem asks for the correct formula to convert temperature from degrees Celsius (C) to degrees Fahrenheit (F).
Recall the relationship between Celsius and Fahrenheit scales: the freezing point of water is 0°C and 32°F, and the boiling point is 100°C and 212°F.
Use the general conversion formula derived from these points: \(F = \frac{9}{5}C + 32\).
Check each given formula against this standard formula to identify which one matches the correct conversion.
Conclude that the correct formula is the one that multiplies Celsius by 9/5 and then adds 32, i.e., \(F = \frac{9}{5}C + 32\).
