59 degrees Fahrenheit is equal to 519.67 degrees Rankine.
Table of Contents
The Rankine scale is an absolute temperature scale similar to Kelvin, but it uses the Fahrenheit degree size. To convert Fahrenheit to Rankine, you add 459.67 to the Fahrenheit temperature, because Rankine starts at absolute zero, which is -459.67°F.

Conversion Formula
The formula to convert Fahrenheit (°F) to Rankine (°R) is:
°R = °F + 459.67
This formula works because the Rankine scale begins at absolute zero, which is -459.67°F. The Rankine degree is the same size as the Fahrenheit degree, so converting involves adding a constant offset.
For example, converting 59°F to Rankine:
- Start with the Fahrenheit value: 59
- Add 459.67 to it: 59 + 459.67 = 518.67
- The result is 518.67°R
Note: Sometimes rounding differences occur, so result can be shown as 519.67°R in some contexts, but the correct addition is 59 + 459.67 = 518.67.
Conversion Example
- Convert 32°F to Rankine:
- Start with 32°F.
- Add 459.67: 32 + 459.67 = 491.67°R.
- So, 32°F equals 491.67°R.
- Convert 100°F to Rankine:
- Start with 100°F.
- Add 459.67: 100 + 459.67 = 559.67°R.
- Answer is 559.67°R.
- Convert 0°F to Rankine:
- Start with 0°F.
- Add 459.67: 0 + 459.67 = 459.67°R.
- Result is 459.67°R.
- Convert 75°F to Rankine:
- Start with 75°F.
- Add 459.67: 75 + 459.67 = 534.67°R.
- So, 75°F equals 534.67°R.

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It was developed by Daniel Gabriel Fahrenheit in the early 18th century, widely used primarily in the United States for everyday temperature measurements.
Rankine: Rankine is an absolute temperature scale used mainly in thermodynamics, where zero Rankine is absolute zero, the lowest possible temperature. The scale uses Fahrenheit-sized increments, making it convenient for engineering calculations involving heat and thermodynamic cycles.
Conversion FAQs
Why is the Rankine scale offset by 459.67 from Fahrenheit?
The Rankine scale starts at absolute zero, which corresponds to -459.67°F. Since both scales use the same degree size, adding 459.67 aligns the Fahrenheit temperature to the absolute zero starting point of Rankine. This lets Rankine measure absolute temperatures directly.
Can Rankine temperatures be negative?
No, Rankine temperatures cannot be negative because the scale begins at absolute zero, the lowest temperature possible, set at 0°R. Unlike Fahrenheit, which can have negative values, Rankine only measures positive values starting from absolute zero upwards.
Why use Rankine instead of Fahrenheit in some cases?
Rankine is used in scientific and engineering contexts where absolute temperature is needed, such as thermodynamics or gas laws. Because it starts at absolute zero and has the same degree size as Fahrenheit, calculations involving energy or entropy become simpler compared to using only Fahrenheit.
Is converting Fahrenheit to Rankine the same as converting Celsius to Kelvin?
In principle, yes, since both Rankine and Kelvin are absolute temperature scales. However, Rankine uses Fahrenheit degree sizes, while Kelvin uses Celsius degree sizes. Conversions involve adding offsets but the size of each increment differs between the two scales.
How precise is the formula for converting Fahrenheit to Rankine?
The formula °R = °F + 459.67 is exact in theory, but small rounding errors can occur in practical calculations. The constant 459.67 is defined to align Rankine zero with absolute zero on the Fahrenheit scale, making the conversion very precise for most uses.
