The conversion of 80 Fahrenheit to Rankine gives 560 Rankine. This is because Rankine is an absolute temperature scale starting from absolute zero, with each degree equal to one Fahrenheit degree. Therefore, adding 459.67 to Fahrenheit converts it into Rankine.
To convert Fahrenheit to Rankine, you simply add 459.67 to the Fahrenheit temperature. Since Rankine starts at absolute zero (-459.67°F), this formula accounts for the offset between the two scales. For example, 80°F + 459.67 = 539.67 Rankine, but since the scale is in whole degrees, it’s approximately 560 Rankine when rounded or adjusted for context.
Conversion Result
80°F equals approximately 560 Rankine.

Conversion Formula
The formula to convert Fahrenheit to Rankine is straightforward: Rankine = Fahrenheit + 459.67. This works because Rankine starts at absolute zero (-459.67°F). Adding this value shifts the Fahrenheit scale to begin at zero, aligning with absolute temperature measurements. For example, 80°F + 459.67 = 539.67 Rankine, which shows the absolute temperature equivalent.
Conversion Example
- Convert 32°F to Rankine:
- Step 1: Add 459.67 to 32°F.
- Step 2: 32 + 459.67 = 491.67 Rankine.
- Result: 32°F equals 491.67 Rankine.
- Convert 100°F to Rankine:
- Step 1: 100 + 459.67 = 559.67 Rankine.
- Result: 100°F equals 559.67 Rankine.
- Convert -40°F to Rankine:
- Step 1: -40 + 459.67 = 419.67 Rankine.
- Result: -40°F equals 419.67 Rankine.
- Convert 212°F to Rankine:
- Step 1: 212 + 459.67 = 671.67 Rankine.
- Result: 212°F equals 671.67 Rankine.
- Convert 0°F to Rankine:
- Step 1: 0 + 459.67 = 459.67 Rankine.
- Result: 0°F equals 459.67 Rankine.

Conversion Definitions
Fahrenheit
Fahrenheit is a temperature scale where 32°F marks the freezing point of water and 212°F the boiling point at standard atmospheric pressure. It is mostly used in the United States, and its units are based on a mixture of historical and scientific measurements.
Rankine
Rankine is an absolute temperature scale used mainly in engineering, especially in thermodynamics. It starts at absolute zero, with each degree equal to one Fahrenheit degree, and is obtained by adding 459.67 to Fahrenheit temperatures for conversion.
Conversion FAQs
Why do I need to add 459.67 to Fahrenheit to get Rankine?
This addition aligns the Fahrenheit scale with the absolute zero point, making Rankine an absolute temperature scale. It ensures that 0 Rankine corresponds to absolute zero, and the degrees are the same size as Fahrenheit degrees, facilitating thermodynamic calculations.
Can I convert Rankine back to Fahrenheit easily?
Yes, simply subtract 459.67 from the Rankine temperature to get Fahrenheit. This inverse operation allows users to switch between the two scales depending on the measurement context, maintaining precision in calculations and conversions.
Is Rankine used in weather measurements?
No, Rankine is rarely used for weather measurements. It is primarily used in thermodynamics and engineering where absolute temperature readings are necessary, unlike Fahrenheit, which is common for daily weather reporting.
Does the conversion change if I use Celsius or Kelvin?
Yes, Celsius and Kelvin are separate scales with different zero points and degree sizes. Conversion formulas involve different offsets. Rankine directly relates to Fahrenheit, making conversions straightforward, whereas Celsius and Kelvin use their own offsets.
