Degree Rankine

°R

Definition

The degree Rankine (°R) is an absolute temperature scale unit that is also used for temperature intervals. It is equal to 5/9 of a kelvin and represents the same temperature interval as degree Fahrenheit, but on an absolute temperature scale rather than a relative one.

History/Origin

Named after William John Macquorn Rankine, the degree Rankine was developed as an absolute temperature scale based on the Fahrenheit scale. For temperature intervals, it provides the same resolution as degree Fahrenheit but is used in absolute temperature measurements.

Current Use

Used in engineering applications, particularly in thermodynamics and heat transfer calculations where absolute temperature measurements are required. It is commonly used in power generation, refrigeration, and aerospace engineering for temperature interval measurements.

Degree Centigrade

°C

Definition

The degree centigrade (°C) is an alternative name for degree Celsius, representing the same temperature interval unit. It is equal to one kelvin when measuring temperature differences and is used interchangeably with degree Celsius in many contexts.

History/Origin

The term "centigrade" was historically used to describe the temperature scale now known as Celsius. It means "hundred degrees" and refers to the 100-degree interval between the freezing and boiling points of water. For temperature intervals, it maintains the same scale as the kelvin.

Current Use

Used interchangeably with degree Celsius in many contexts, particularly in older literature and some engineering applications. It represents the same temperature interval as degree Celsius and is commonly used in temperature difference measurements.
