Samantha Nicole1 kelvin equals 1.8 rankine.
The kelvin and rankine scales both measure temperature, but kelvin uses increments based on Celsius degrees while rankine uses increments based on Fahrenheit degrees. To convert kelvin to rankine, you multiply by 1.8 because each kelvin degree corresponds to 1.8 rankine degrees.

Conversion Formula
The formula to convert kelvin (K) to rankine (°R) is:
Rankine = Kelvin × 1.8
This works because the kelvin scale increments are the same size as Celsius degrees, but rankine scale uses Fahrenheit-sized increments, which are 1.8 times larger. Since both scales start at absolute zero, there is no offset needed.
Example:
- Given 1 kelvin, multiply by 1.8.
- 1 K × 1.8 = 1.8 °R
- So, 1 kelvin equals 1.8 rankine.
Conversion Example
- Convert 5 kelvin to rankine:
- Multiply 5 by 1.8.
- 5 × 1.8 = 9 rankine.
- Answer: 5 K = 9 °R.
- Convert 10.5 kelvin to rankine:
- 10.5 × 1.8 = 18.9 rankine.
- Answer: 10.5 K = 18.9 °R.
- Convert 0 kelvin to rankine:
- 0 × 1.8 = 0 rankine.
- Answer: Absolute zero at 0 K equals 0 °R.
- Convert 20 kelvin to rankine:
- 20 × 1.8 = 36 rankine.
- Answer: 20 K = 36 °R.

Conversion Definitions
Kelvin: Kelvin is the SI base unit of temperature, measuring thermodynamic temperature starting at absolute zero. Its increments are equal to Celsius degrees, but with zero at absolute zero (-273.15°C). It is widely used in science and engineering for precise temperature measurements.
Rankine: Rankine is an absolute temperature scale based on Fahrenheit degrees, starting at absolute zero. One rankine degree equals one Fahrenheit degree increment. It is used mostly in engineering fields in the United States, particularly for thermodynamic temperature calculations.
Conversion FAQs
Why does the kelvin to rankine conversion only multiply by 1.8?
The kelvin and rankine scales both start at absolute zero, meaning no offset is needed. The difference lies in the size of the degree increments: kelvin uses Celsius-sized increments, rankine uses Fahrenheit-sized ones, which are 1.8 times larger. So, conversion requires multiplying by 1.8.
Can kelvin values be negative when converting to rankine?
Kelvin scale temperatures cannot be negative since it starts at absolute zero. However, if negative kelvin values are entered mistakenly, the conversion will produce negative rankine values mathematically, though physically those temperatures don’t exist.
Is the conversion between kelvin and rankine reversible?
Yes, to convert rankine back to kelvin, divide the rankine value by 1.8. Both scales share the same zero point, so no additional adjustment is needed for the reverse conversion.
Are kelvin and rankine used in everyday temperature readings?
No, kelvin and rankine are uncommon for daily temperature measurements. Celsius and Fahrenheit are preferred for weather and household uses. Kelvin is mainly scientific, rankine mostly in specific engineering fields.
Does the conversion formula change for temperatures above absolute zero?
No, the formula Rankine = Kelvin × 1.8 holds true for all temperatures above absolute zero because both scales have same zero point and proportional degree sizes.
