Unit Explanations
Fahrenheit°F
Source UnitFahrenheit is a temperature measurement scale where the freezing point of water is defined as 32 degrees Fahrenheit (°F) and the boiling point as 212°F at standard atmospheric pressure. This scale divides the interval between the freezing and boiling points of water into 180 equal parts. It is predominantly used in the United States and some Caribbean nations for non-scientific applications, making it one of the few non-metric temperature scales still in use.
Current Use
Today, the Fahrenheit scale is primarily used in the United States and a few Caribbean countries for non-scientific applications, such as weather forecasts, cooking, and air conditioning. It is less commonly used in scientific contexts where the Celsius scale or Kelvin scale is preferred.
Fun Fact
The Fahrenheit scale was the first widely used temperature scale.
Rankine°R
Target UnitThe Rankine scale is an absolute temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine. It is primarily used in thermodynamics and engineering fields in the United States. The Rankine scale sets its zero point at absolute zero, the same as the Kelvin scale, but uses degrees Fahrenheit for its increments. This means that a change of 1 degree Rankine is equivalent to a change of 1 degree Fahrenheit. The formula for converting Fahrenheit to Rankine is °R = °F + 459.67.
Current Use
The Rankine scale is currently used in engineering fields, particularly in the United States, for thermodynamic calculations. Although it is not as widely used as it once was, Rankine is still relevant in certain niche areas where absolute temperature measurements are required. Industries such as aerospace, mechanical engineering, and HVAC (heating, ventilation, and air conditioning) utilize Rankine for specific applications.
Fun Fact
Rankine is mostly used in the US, similar to how Kelvin is used worldwide.
Convert Fahrenheit to Rankine (°F to °R)
Convert Fahrenheit (°F) to Rankine (°R). When performing thermodynamic equations like the Ideal Gas Law using US units, you must convert Fahrenheit to absolute Rankine. Simply shifting the scale makes the equations valid.
Add 459.67 to the Fahrenheit temperature. For example, 32 °F + 459.67 = 491.67 °R.
Fahrenheit (°F)
Definition
The customary temperature scale of the United States.
Origins & History
First standardized temperature scale to be widely used.
Rankine (°R)
Definition
Absolute temperature scale with Fahrenheit-sized degrees.
Origins & History
Created to allow absolute zero calculations without leaving the Imperial system.

Definition
Fahrenheit is a temperature measurement scale where the freezing point of water is defined as 32 degrees Fahrenheit (°F) and the boiling point as 212°F at standard atmospheric pressure. This scale divides the interval between the freezing and boiling points of water into 180 equal parts. It is predominantly used in the United States and some Caribbean nations for non-scientific applications, making it one of the few non-metric temperature scales still in use.
History & Origin
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit, a Polish-German physicist, in 1724. He based his scale on three reference points: the lowest temperature he could achieve with a mixture of ice, water, and ammonium chloride (0°F), the freezing point of water (32°F), and the average human body temperature (approximately 96°F at the time, now adjusted to 98.6°F).
Etymology: The term 'Fahrenheit' originates from Daniel Gabriel Fahrenheit's last name.
Current Use
Today, the Fahrenheit scale is primarily used in the United States and a few Caribbean countries for non-scientific applications, such as weather forecasts, cooking, and air conditioning. It is less commonly used in scientific contexts where the Celsius scale or Kelvin scale is preferred.
💡 Fun Facts
- •The Fahrenheit scale was the first widely used temperature scale.
- •Fahrenheit initially set 0°F as the lowest temperature he could create in his lab.
- •Fahrenheit's original human body temperature scale was adjusted from 96°F to 98.6°F.

History & Origin
The Rankine scale was proposed by William John Macquorn Rankine in 1859. Rankine was a key figure in the development of thermodynamics and sought to create a scale that paralleled Kelvin's absolute temperature scale but used Fahrenheit degrees instead of Celsius. The Rankine scale became particularly useful in the United States, where Fahrenheit was the preferred temperature measurement system. Over time, the Rankine scale has been largely replaced by Kelvin in scientific contexts but remains in use in certain engineering fields.

- •Rankine is mostly used in the US, similar to how Kelvin is used worldwide.
- •The Rankine scale uses the same degree size as Fahrenheit, not Celsius.
- •It was one of the first scales to define absolute zero, similar to Kelvin.
