10 kelvin (K) is equal to 18.0000 rankine (°R).
Table of Contents
To convert kelvin to rankine, you multiply the temperature value by 1.8 because the rankine scale is based on the Fahrenheit degree size but starts at absolute zero, just like kelvin. Thus, 10 K times 1.8 equals 18 °R.

Conversion Formula
The formula to convert kelvin (K) to rankine (°R) is:
°R = K × 1.8
This formula works because the rankine scale uses Fahrenheit degree increments, which are 1.8 times larger than kelvin degrees. Both start at absolute zero, so no offset is needed, just a multiplication factor. Multiplying by 1.8 changes the unit scale from kelvin to rankine.
Example calculation for 10 K:
- Start with 10 kelvin.
- Multiply by 1.8: 10 × 1.8 = 18.
- The result is 18 rankine.
Conversion Example
- Convert 25 K to rankine:
- Take 25 kelvin.
- Multiply 25 by 1.8, which equals 45.
- So, 25 K = 45 °R.
- Convert 0 K to rankine:
- 0 kelvin is absolute zero.
- Multiply 0 by 1.8 gives 0.
- So, 0 K = 0 °R.
- Convert 100 K to rankine:
- Start with 100 kelvin.
- Multiply 100 × 1.8 = 180.
- This means 100 K is 180 °R.
- Convert 15.5 K to rankine:
- Take 15.5 kelvin.
- Multiply 15.5 by 1.8 = 27.9.
- So 15.5 K equals 27.9 °R.
- Convert -5 K to rankine:
- Negative kelvin is physically impossible but mathematically:
- -5 × 1.8 = -9.
- So, -5 K corresponds to -9 °R theoretically.

Conversion Definitions
K (kelvin): Kelvin is the SI base unit for temperature measurement, starting at absolute zero where molecular motion stops. It uses the same increments as Celsius but starts at -273.15°C, making it useful for scientific temperature scales without negative values.
Rankine (°R): Rankine is an absolute temperature scale used mainly in engineering fields in the US, based on Fahrenheit degree increments. It starts at absolute zero like kelvin but uses the Fahrenheit size degrees, so 1 °R equals 5/9 K.
Conversion FAQs
Can I convert kelvin to rankine by adding a number instead of multiplying?
No, converting kelvin to rankine does not involve addition because both scales start at absolute zero. The difference is in the size of each degree unit, so only multiplication by 1.8 is required, not adding any offset.
Is the rankine scale used worldwide?
The rankine scale is mostly used in the United States, especially in engineering and thermodynamics. Other countries prefer using kelvin or Celsius scales, so rankine is less common globally but still important in certain industries.
Why does kelvin to rankine conversion use 1.8 as factor?
Because rankine degrees are sized the same as Fahrenheit degrees, which are 1.8 times larger than kelvin degrees. Since both kelvin and rankine start at absolute zero, only the degree size differs, requiring multiplication by 1.8.
Can kelvin have negative values when converting to rankine?
Kelvin temperatures cannot be negative in physical reality because absolute zero is 0 K. However, mathematically if negative kelvin values appear, multiplying by 1.8 will produce negative rankine values, but such values have no physical meaning.
How precise is converting kelvin to rankine using the formula?
The conversion formula provides exact conversion between kelvin and rankine because they are directly proportional scales. The only limitation is measurement precision of the original kelvin value used.
