125 kelvin is equal to 225 rankine.
To convert kelvin to rankine, multiply the kelvin temperature by 1.8. This conversion works because both scales start at absolute zero, but rankine increments in degrees Fahrenheit size, which is 1.8 times the kelvin degree.

Conversion Formula
The formula to convert kelvin (K) to rankine (°R) is:
°R = K × 1.8
Because both kelvin and rankine scales start at absolute zero, no offset is needed. The difference is the size of the degree: 1 kelvin equals 1.8 rankine degrees. Multiplying kelvin temperature by 1.8 converts it to rankine.
For example, to convert 125 K to °R:
- Multiply 125 by 1.8
- 125 × 1.8 = 225
- So, 125 kelvin equals 225 rankine
Conversion Example
- Convert 130 K to rankine
- Multiply 130 by 1.8
- 130 × 1.8 = 234
- Result: 130 K = 234 °R
- Convert 110 K to rankine
- Multiply 110 by 1.8
- 110 × 1.8 = 198
- Result: 110 K = 198 °R
- Convert 140.5 K to rankine
- Multiply 140.5 by 1.8
- 140.5 × 1.8 = 252.9
- Result: 140.5 K = 252.9 °R
- Convert 115 K to rankine
- Multiply 115 by 1.8
- 115 × 1.8 = 207
- Result: 115 K = 207 °R

Conversion Definitions
Kelvin: Kelvin is the SI base unit for temperature measurement, starting at absolute zero, the lowest possible temperature. One kelvin increment equals the same temperature change as one degree Celsius, but kelvin does not use negative values, making it useful in scientific calculations.
Rankine: Rankine is an absolute temperature scale used primarily in thermodynamics, starting at absolute zero like kelvin. It uses Fahrenheit degree increments, so one rankine degree equals one degree Fahrenheit. Rankine is often used in engineering fields in the United States.
Conversion FAQs
Why multiply kelvin by 1.8 to get rankine?
Because the rankine scale uses Fahrenheit-sized degrees, which are 1.8 times bigger than kelvin degrees. Both scales start at absolute zero, so only the size of the degree differs. Multiplying kelvin temperature by 1.8 scales it to rankine accurately.
Can I convert rankine back to kelvin?
Yes, to convert rankine to kelvin, divide the rankine value by 1.8. This reverses the earlier multiplication, giving the original kelvin temperature since the scales share the same zero point.
Is 125 kelvin a common temperature to convert?
125 kelvin represents a very cold temperature, below freezing of water. While not common in everyday life, it appears in scientific contexts like cryogenics or space science. Conversion to rankine helps engineers and scientists working with Fahrenheit-based systems.
What are practical uses for rankine scale?
Rankine scale is used in thermodynamics and engineering, particularly in the US. It helps when calculations involve Fahrenheit units but require absolute temperature reference, like in gas law equations or heat engine efficiency calculations.
Does converting kelvin to rankine affect measurement accuracy?
No, conversion does not affect accuracy because both scales start at absolute zero and the conversion is a precise multiplication. Any measurement error comes from the original temperature reading, not the conversion itself.
