Question

Which of the following formulas would you use to convert a temperature initially taken in degrees Fahrenheit to degrees Celsius?

Question 57 options:

C = F – 273

C = 9/5F + 32°

C = 5/9(F - 32°)

C = 5/9F - 32°

Answer 1

C = 5/9(F - 32°)

Step-by-step explanation:

If we compare the farenheit degree scales with the celsius degree scale, we find that the intervals between the same reference points are 180 ° farenheit and 100 ° celsius. 180 degrees farenheit are needed to cover the same temperature range of 100 degrees Celsius. From this information the unit factors of temperature change can be established.

Factor: 1 °C/1.8°F= 5/9

Also, to convert from ° F to ° C, we must subtract 32 degrees farenheit to reach the zero point of the celsius scale.

Then, the correct formula is:

C = 5/9(F - 32°)
