National Council of Examiners for Engineering and Surveying (NCEES) Fundamentals of Engineering (FE) Other Disciplines Practice Exam

Question: 1 / 400

If the temperature in Fahrenheit is set to 0, what is the equivalent in Rankine?

459.67 R

To convert a temperature from Fahrenheit to Rankine, you can use the relationship that Rankine is essentially the Fahrenheit scale shifted by an absolute zero value. The formula for converting Fahrenheit (F) to Rankine (R) is:

\[ R = F + 459.67 \]

This means that you take the temperature in Fahrenheit and add 459.67 to obtain the temperature in Rankine.

In this case, when the temperature is set to 0 degrees Fahrenheit, the conversion is calculated as follows:

\[ R = 0 + 459.67 = 459.67 R \]

This shows that 0 degrees Fahrenheit is equivalent to 459.67 degrees Rankine. It underscores the fact that the Rankine scale, like the Kelvin scale, is an absolute temperature scale.

The other options do not reflect correct conversions from 0 degrees Fahrenheit. For instance, 0 Rankine would imply a temperature of absolute zero, which is not achievable in theory. Similarly, 32 Rankine and 273.15 Rankine do not correspond to any valid conversion from 0 degrees Fahrenheit.
