10 kelvin (K) is equivalent to 18.0 rankine (°R).
The conversion from kelvin to rankine is done by multiplying the kelvin temperature by 1.8 because both scales start at absolute zero but use different increments per unit. Rankine degrees are larger, so the factor accounts for this difference.

Conversion Formula
The formula to convert kelvin (K) to rankine (°R) is:
°R = K × 1.8
Kelvin and rankine both measure absolute temperature but use different scales. Kelvin uses Celsius degree increments, while rankine uses Fahrenheit degree increments, which are 1.8 times larger. Multiplying kelvin by 1.8 accounts that difference.
Example:
- Given 10 K, multiply 10 × 1.8 = 18 °R
- This means 10 kelvin is equal to 18 rankine.
Conversion Example
Here are some examples converting kelvin to rankine:
- Example 1: 5 K
- Multiply 5 × 1.8 = 9 °R
- So, 5 kelvin equals 9 rankine.
- Example 2: 20 K
- Calculate 20 × 1.8 = 36 °R
- Therefore, 20 kelvin is 36 rankine.
- Example 3: 0 K
- Zero kelvin times 1.8 equals 0 °R
- Absolute zero on both scales aligned.
- Example 4: 100 K
- Multiply 100 × 1.8 = 180 °R
- 100 kelvin equals 180 rankine.

Conversion Definitions
Kelvin (k): Kelvin is an absolute temperature scale starting at absolute zero, where all particle motion theoretically stops. It increases in increments equal to 1 degree Celsius, widely used in scientific temperature measurements, especially in physics and thermodynamics.
Rankine (rankine): Rankine is an absolute temperature scale based on Fahrenheit degrees, beginning at absolute zero. Each degree rankine equals one degree Fahrenheit, used mostly in engineering fields in the United States where Fahrenheit is common.
Conversion FAQs
Why is the kelvin to rankine conversion a multiplication by 1.8?
Because kelvin increments match Celsius degrees and rankine increments match Fahrenheit degrees, and since one Fahrenheit degree is 1.8 times larger than one Celsius degree, multiplying by 1.8 converts kelvin to rankine correctly.
Can kelvin values be negative when converting to rankine?
Kelvin values represent absolute temperature and cannot be negative in real physical terms. However, mathematically, the formula allows negative inputs, resulting in negative rankine values, but these don’t correspond to meaningful temperatures.
Is the rankine scale commonly used?
Rankine is less common globally but still used in some engineering fields in the US that prefer Fahrenheit units. It aligns well with absolute zero measurements like kelvin but uses Fahrenheit-sized degree increments.
How precise is the conversion from kelvin to rankine?
The conversion is exact because it’s a simple linear multiplication by 1.8. The precision depends only on how many decimal places you keep in calculations or display.
Does this conversion affect temperature differences or just absolute values?
Both absolute temperatures and temperature differences convert by the same factor 1.8. For example, a difference of 10 kelvin corresponds to a difference of 18 rankine degrees.
