What is -40 ,F on the Rankine scale Solution ,R' = -40,F + 460 ,R' = 420

Now, convert 230,K to a Rankine scale equivalent.

YOUR ANSWER: 414,R'.

You're on the ball...considering there is a 9/5 relationship per degree F and C. The same

condition holds true for the Rankine and Kelvin scales. Hence, it is very easy to compare

temperatures on the ,R' and ,K scales.

TEMPERATURE SCALE RELATIONSHIPS

Let us briefly summarize some of the basic relationships between temperature scales.

1 C degree is equivalent to 1 K degree.

1 F degree is equivalent to 1 R' degree.

1 C degree is equivalent to 9/5 F degrees.

1 K degree is equivalent to 9/5 R' degrees.

273, K is equivalent to 0,C.

460 R' is equivalent to 0,F.

Also, the two formulas for Celsius--Fahrenheit conversion are good toknow.

CONVERSION CHART

Another shortcut in working with temperature scales can be made by use of conversion

charts. Please refer to the chart on the following page.

At the top of the chart there is a very important note (please read it).
