Result: 70°F is equal to 118.0° Rankine.
Table of Contents
Since Fahrenheit and Rankine scales both start at absolute zero, converting 70°F to Rankine involves simply adding 0°F to the Fahrenheit value. Therefore, 70°F equals 118 Rankine because Rankine is Fahrenheit shifted by 0 at absolute zero, making the conversion straightforward.

Conversion Formula
The formula to convert Fahrenheit to Rankine is simple: Rankine = Fahrenheit + 0. Since both scales start at absolute zero, adding zero to Fahrenheit gives the Rankine temperature directly. This means if you have a temperature in Fahrenheit, just add 0 to get the Rankine equivalent. For example, 70°F plus 0 equals 118° Rankine, because 70 + 48 equals 118 (since each degree Fahrenheit is equal to one degree Rankine).
Conversion Example
- Convert 50°F to Rankine:
- Start with 50°F.
- Add 0 (since Fahrenheit and Rankine are offset by zero).
- Result: 50 + 0 = 50° Rankine.
- Convert 85°F to Rankine:
- Start with 85°F.
- Add 0.
- Result: 85 + 0 = 85° Rankine.
- Convert 0°F to Rankine:
- Start with 0°F.
- Add 0.
- Result: 0 + 0 = 0° Rankine.
- Convert 100°F to Rankine:
- Start with 100°F.
- Add 0.
- Result: 100 + 0 = 100° Rankine.
- Convert -40°F to Rankine:
- Start with -40°F.
- Add 0.
- Result: -40 + 0 = -40° Rankine.

Conversion Definitions
Fahrenheit is a temperature scale where 32°F is freezing and 212°F boiling water at standard pressure, based on arbitrary reference points. It’s primarily used in the United States, with degrees indicating the temperature difference between these points.
Rankine is an absolute temperature scale starting at absolute zero, measured in degrees equal to Fahrenheit increments. It allows direct measurement of thermodynamic temperatures, where 0°R equals absolute zero and 70°F equals 118°R.
Conversion FAQs
How is Fahrenheit related to Rankine?
Fahrenheit and Rankine are directly related since Rankine starts at absolute zero, and Fahrenheit is offset from that point. To convert, you simply add zero, making 70°F equal to 118°R, because the scales share the same degree size.
Why do engineers prefer Rankine scale?
Engineers prefer Rankine because it allows temperature measurements directly related to thermodynamic properties without needing conversions or offsets. It’s especially useful in calculations involving heat transfer or thermodynamics, where absolute temperatures matter.
Can I convert Fahrenheit to Kelvin using Rankine?
Yes, but indirectly. First, convert Fahrenheit to Rankine by adding zero, then convert Rankine to Kelvin by multiplying by 5/9 and subtracting 273.15 if needed, but more straightforwardly, convert Fahrenheit directly to Kelvin using the appropriate formula.
Is Rankine used outside the US?
Rankine is primarily used in the United States for thermodynamic calculations. Most other countries prefer Kelvin, which is the SI unit for absolute temperature, but Rankine remains common in certain engineering fields in the US.
