## How to convert Fahrenheit to Rankine (°F to °R)

The formula for converting Fahrenheit to Rankine is: °R = °F + 459.67. To calculate the Fahrenheit value in Rankine first substitute the Fahrenheit value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 Fahrenheit in Rankine we follow these steps:

°R = °F + 459.67

°R = 1 + 459.67

°R = 460.67

In other words, 1 Fahrenheit is equal to 460.67 Rankine.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 4 Fahrenheit to Rankine is:

- Understand the conversion formula: °R = °F + 459.67
- Substitute the required value. In this case we substitute 4 for °F so the formula becomes: °R = 4 + 459.67
- Calculate the result using the provided values. In our example the result is: 4 + 459.67 = 463.67 °R

In summary, 4 Fahrenheit is equal to 463.67 Rankine.

## Converting Rankine to Fahrenheit

Converting temperatures from Rankine (°R) to Fahrenheit (°F) involves a simple mathematical relationship. In the Rankine scale, absolute zero is 0 °R, and each degree Rankine is equivalent to a degree Fahrenheit. To convert a temperature from Rankine to Fahrenheit, you use the following formula: °F = °R - 459.67So, if you have a temperature in Rankine and you want to convert it to Fahrenheit, you subtract 459.67 from the temperature in Rankine to get the equivalent temperature in Fahrenheit. Conversely, to convert a temperature from Fahrenheit to Rankine, you use the formula: °R = °F + 459.67.This formula adds 459.67 to the temperature in Fahrenheit to get the equivalent temperature in Rankine.## Conversion Unit Definitions

### What is a Fahrenheit?

Temperature Scale: The Fahrenheit scale divides the temperature range between the freezing and boiling points of water into 180 equal divisions or degrees. On this scale, the freezing point of water is defined as 32 degrees Fahrenheit (°F), and the boiling point of water is defined as 212 degrees Fahrenheit (°F) at standard atmospheric pressure.

Origin: The Fahrenheit scale was originally based on three reference points: the freezing point of a brine solution, the average human body temperature, and the body temperature of horses. However, over time, these reference points have been refined and standardized to the freezing and boiling points of water.

Metric System: Fahrenheit is not part of the metric system but is still used in certain countries. It is primarily used in the United States, along with a few other nations that have historical ties to the United States or limited cultural influences from it.

Conversion: Fahrenheit can be converted to other temperature scales. One common conversion is to Celsius. The formula to convert Fahrenheit to Celsius is: Celsius = (Fahrenheit - 32) x 5/9. Fahrenheit can also be converted to the Kelvin scale by first converting to Celsius and then adding 273.15.

Symbol: The symbol for degrees Fahrenheit is "°F". For example, a temperature measurement of 75 degrees Fahrenheit would be written as 75 °F.

Common Uses: Fahrenheit is commonly used in everyday contexts in countries that primarily use the Fahrenheit scale. It is used in weather forecasts, discussions of outdoor temperatures, oven and cooking temperatures, and temperature readings on household thermometers.

International Usage: The Fahrenheit scale is not widely used internationally, as the Celsius scale is the standard for temperature measurement in most countries around the world. However, it is still relevant and used in the United States and a few other nations.

### What is a Rankine?

Absolute Temperature Scale: The Rankine scale is an absolute temperature scale that is similar to the Kelvin scale but uses a different zero point. On the Rankine scale, absolute zero is defined as 0 Rankine (°R), which is equal to -459.67 degrees Fahrenheit. The size of the Rankine degree is the same as the Fahrenheit degree, so the temperature increments are the same.

Conversion: Rankine can be converted to other temperature scales. One common conversion is to the Fahrenheit scale. The formula to convert Rankine to Fahrenheit is: Fahrenheit = Rankine - 459.67. Rankine can also be converted to the Kelvin scale by dividing the Rankine measurement by 1.8.

Symbol: The symbol for degrees Rankine is "°R". For example, a temperature measurement of 550 degrees Rankine would be written as 550 °R.

Common Uses: Rankine is primarily used in engineering and thermodynamics, especially in the United States. It is often used in the analysis and calculation of temperature in power generation, refrigeration, and other thermal systems.

Relationship to Other Scales: The Rankine scale is closely related to the Fahrenheit scale, as they have the same size of degree. However, Rankine is an absolute temperature scale, similar to the Kelvin scale. In fact, the Rankine scale and the Kelvin scale have the same temperature increments, with the only difference being the zero points.

International Usage: The Rankine scale is not widely used internationally, as the Kelvin scale is the standard for absolute temperature measurement in most countries around the world. The Rankine scale is mainly used in the United States, particularly in engineering and industrial applications.
