Result: 70°F equals 519.67 Rankine.
To convert Fahrenheit to Rankine, you simply add 459.67 to the Fahrenheit temperature. Since Rankine is an absolute temperature scale that starts at absolute zero, this addition shifts the Fahrenheit scale to start at absolute zero as well. Therefore, 70°F plus 459.67 gives the Rankine value.

Conversion Formula
The formula for converting Fahrenheit (f) to Rankine (R) is R = f + 459.67. This works because Rankine is an absolute temperature scale similar to Kelvin, but based on Fahrenheit increments. The zero point of Rankine is absolute zero, which is -459.67°F. Adding 459.67 to any Fahrenheit temperature shifts it to the Rankine scale. For example, 70°F plus 459.67 equals 519.67 Rankine.
Conversion Example
- Convert 30°F to Rankine:
- Start with the formula R = f + 459.67
- Plug in 30: R = 30 + 459.67
- Calculate: R = 489.67 Rankine
- Convert -20°F to Rankine:
- R = -20 + 459.67
- R = 439.67 Rankine
- Convert 100°F to Rankine:
- R = 100 + 459.67
- R = 559.67 Rankine

Conversion Definitions
Fahrenheit (f) is a temperature scale where water freezes at 32°F and boils at 212°F under standard conditions, primarily used in the United States. It measures temperature relative to a mixture of ice, salt, and water, with increments representing 1°F.
Rankine (R) is an absolute temperature scale starting at absolute zero, where 0 R equals -459.67°F. It uses the same degree increments as Fahrenheit, but begins at absolute zero, making it useful for thermodynamic calculations.
Conversion FAQs
How does adding 459.67 convert Fahrenheit to Rankine?
Adding 459.67 to Fahrenheit shifts the temperature scale from relative to absolute zero, aligning Fahrenheit with Rankine. Since Rankine starts at absolute zero, this addition accounts for the offset between the two scales, making conversions straightforward.
Is Rankine used in scientific measurements?
Yes, Rankine is used primarily in thermodynamics and engineering fields in the United States. It allows for calculations involving absolute temperatures without converting to Kelvin, especially when working with Fahrenheit-based systems.
What happens if I convert 0°F to Rankine?
By adding 459.67, zero Fahrenheit converts to 459.67 Rankine, which is the absolute zero point relative to the Fahrenheit scale. This makes Rankine useful for measurements that require an absolute temperature starting point.
Can I convert Fahrenheit to Kelvin directly?
No, Fahrenheit to Kelvin conversion requires an intermediate step. First, convert Fahrenheit to Celsius, then Celsius to Kelvin. Rankine provides a more direct path if you are working within Fahrenheit measurements, as it shares degree increments with Fahrenheit.
