Hey Guys! Welcome you onboard. The above calculator is an instant Rankine to Fahrenheit Converter. You can put any value in Rankine temperature scale and get Fahrenheit value in return on the fly.

#### Rankine to Fahrenheit Converter

You need to convert temperature from one scale to another based on the technical requirements of the project and the research you are working on. Converting temperature from one scale to another is just one click away, setting you free from the hassle of manually converting these values.

##### Formula Used

Following formula is used to convert temperature from Rankine scale to Fahrenheit scale.

ºF = ºR – 459.67

The Fahrenheit temperature is equal to the Rankine temperature scale minus 459.67, terming that 0 °F is equal to 459.67 °R.

##### Example

Convert 50 Rankine temperature to Fahrenheit temperature.

We know the formula

ºF = ºR – 459.67

Just put the values in the given formula where R = 50

ºF = 50 – 459.67 = – 409.67

We can conclude from the equation above, 50 Rankine temperature is equal to -409.67 in Fahrenheit Scale.

##### Table with Some Common Values

Following table shows the common values used in Rankine to Fahrenheit Converter.

##### Rankine Temperature

Rankine temperature is termed as the absolute scale of thermodynamic temperature and is denoted by ºR. Many engineering systems involving heat commutations widely use this scale for the temperature measurements.

This temperature scale is named after William John Macquorn Rankine who introduced it in 1859.

The zero Fahrenheit is equal to 459.67 in the Rankine scale. These values increment gradually with the same factor no matter what value in Fahrenheit you aim to achieve. The water freezes at **491.67 ºR** and **32 ºF** and boils at **212 ºF or 671.64 ºR.**

It is important to note that Fahrenheit and Rankine’s scale don’t share a common point and 0 ºR is equal to -459.67 ºF. Nevertheless, once these values are reserved for these scales, both increment with one degree on the scale i.e. 1 ºR will be equal to -458.67 ºF.

##### Fahrenheit Temperature

Fahrenheit is termed as a temperature at which water freezes at **32 ºF** and boils at **212 ºF, **pointing out that boiling and freezing point values are equally separated by **180** points.

All these values in Rankine and Fahrenheit scales are calculated and measured at sea level with standard atmospheric pressure.

**History**

Fahrenheit is named after German physicist Daniel Gabriel Fahrenheit. He proposed this scale in 1724 based on the experiment on the ice-salt mixture. After a successful attempt, he concluded that water freezing point is **30 ºF**, while the normal body temperature was around **90 ºF. **

With the passage of time, as he performed further experiments, he added that previous values reserved for the freezing point of water and normal body temperatures were not the correct ones. Later on, these values were adjusted, terming **32 ºF** as the freezing point of water and **98 ºF** as the normal body temperature. Fahrenheit temperature scale has long been used as a fixed reference for a thermometer.
