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 Celsius

°C

Definition

The degree Celsius (°C) is a unit of temperature interval equal to one kelvin. When measuring temperature differences rather than absolute temperatures, one degree Celsius equals one kelvin, making it equivalent for interval measurements in the Celsius temperature scale.

History/Origin

Named after Anders Celsius, the degree Celsius was originally defined as 1/100 of the temperature difference between the freezing and boiling points of water. For temperature intervals, it maintains the same scale as the kelvin, providing a practical unit for everyday temperature difference measurements.

Current Use

Commonly used in everyday applications, weather reporting, and engineering for measuring temperature differences. It is widely used in HVAC systems, industrial processes, and scientific research where temperature intervals are measured in Celsius scale.
