Which temperature scale uses absolute zero as its zero point and has degree intervals equal to Fahrenheit?

• A. Fahrenheit
• B. Celsius
• C. Kelvin
• D. Rankine

Answer: (D)

Rankine is defined with absolute zero at the zero point and uses temperature steps the same size as Fahrenheit degrees. That means a one-unit change in Rankine corresponds to a one-degree Fahrenheit change, while the zero point corresponds to absolute zero (-459.67 °F in Fahrenheit terms). So Rankine combines the idea of an absolute-temperature zero with Fahrenheit-sized increments. Kelvin also has absolute zero, but its degree size matches Celsius, not Fahrenheit. Celsius starts from a non-absolute zero reference. If you ever convert, note that Rankine equals Fahrenheit plus 459.67.
