Convert Rankine to Fahrenheit

Rankine

Definition: Rankine is an absolute thermodynamic temperature scale whose zero point is absolute zero. One degree Rankine has the same interval size as one degree Fahrenheit, equal to five-ninths of a kelvin.

Fahrenheit

Definition: The Fahrenheit (symbol: °F) is a unit of temperature that was widely used prior to metrication. It is currently defined by two fixed points: the temperature at which water freezes, 32°F, and the boiling point of water, 212°F, both at sea level and standard atmospheric pressure. The interval between the freezing and boiling point is divided into 180 equal parts.

Current use: Until the 1960's the Fahrenheit scale was the primary scale used in English-speaking countries. Today, most countries around the world use the Celsius temperature scale instead, many having made the change during their metrication processes (conversion to using the metric system of units). However, the Fahrenheit scale is still used as the official temperature scale in a number of countries, including the United States (as well as its unincorporated territories), the Bahamas, Belize, the Cayman Islands, and a few others.
