Samantha Nicole10 kelvin (K) equals 18.0 rankine (°R). This is found by multiplying the kelvin value by 1.8, since 1 kelvin is equal to 1.8 rankine.
The conversion from kelvin to rankine is straightforward because both scales start from absolute zero, but rankine uses the Fahrenheit degree size. Multiplying kelvin temperature by 1.8 gives the equivalent rankine value, reflecting the different unit sizes.

Conversion Formula
To convert kelvin (K) to rankine (°R), you multiply the temperature in kelvin by 1.8. This formula works because rankine degrees are based on the Fahrenheit scale, which has a degree size of 5/9 the size of a kelvin degree.
Here is the formula:
°R = K × 1.8
Since both kelvin and rankine start at absolute zero (0 K = 0 °R), no offset is needed, only the scaling factor.
Example calculation for 10 K:
- Multiply 10 K by 1.8
- 10 × 1.8 = 18 °R
- Therefore, 10 kelvin equals 18 rankine.
Conversion Example
- Convert 25 K to rankine:
- Multiply 25 by 1.8
- 25 × 1.8 = 45 °R
- Therefore, 25 K = 45 °R.
- Convert 0 K to rankine:
- Multiply 0 by 1.8
- 0 × 1.8 = 0 °R
- Absolute zero is same in both scales.
- Convert 100 K to rankine:
- 100 × 1.8 = 180 °R
- Just multiply kelvin by 1.8 for rankine.
- Convert 15.5 K to rankine:
- 15.5 × 1.8 = 27.9 °R
- This shows decimal kelvin values convert same way.

Conversion Definitions
Kelvin (K): Kelvin is a temperature scale based on absolute zero, the lowest possible temperature where thermal motion stops. It uses the same increment size as Celsius, but starts at zero kelvin, which equals -273.15°C. Kelvin is widely used in science and engineering for precise temperature measurements.
Rankine (°R): Rankine is an absolute temperature scale similar to kelvin, but uses Fahrenheit degree increments. Zero rankine corresponds to absolute zero, and each degree rankine equals one Fahrenheit degree. This scale is used mainly in certain engineering fields, especially in the U.S., dealing with thermodynamics.
Conversion FAQs
Why does the conversion from kelvin to rankine require multiplying by 1.8?
The kelvin and rankine scales both start from absolute zero, but rankine uses Fahrenheit degree increments, which are 1.8 times larger than kelvin or Celsius degrees. Multiplying by 1.8 adjusts the kelvin value to match the larger degree size of rankine, ensuring accurate conversion.
Can kelvin values be negative when converting to rankine?
No, kelvin values cannot be negative because kelvin starts at absolute zero (0 K). Therefore, when converting to rankine, which also starts at absolute zero, negative kelvin values do not exist, and negative rankine values are theoretically invalid for physical temperatures.
Is there an offset needed when converting kelvin to rankine?
No, the kelvin and rankine scales both begin at absolute zero, so no offset is necessary in the conversion. Only a scaling factor of 1.8 is applied to convert the size of kelvin degrees to rankine degrees.
What practical situations use kelvin to rankine conversions?
Conversions between kelvin and rankine are common in thermodynamics and engineering fields, especially when working with temperature data in SI units and imperial units. Rankine is preferred in some U.S. engineering applications dealing with heat and energy calculations.
Can the conversion tool handle decimal inputs accurately?
Yes, the provided conversion tool accepts decimal values and calculates the rankine equivalent by multiplying by 1.8, then rounding to four decimal places. This ensures precise conversion for fractional kelvin temperatures.
