125 kelvin is equal to 225 rankine.
Table of Contents
To convert kelvin to rankine, you multiply the kelvin temperature by a factor of 1.8 because rankine uses the Fahrenheit scale’s degree size, which is 1.8 times larger than kelvin’s. This conversion makes it easy to switch between absolute temperature scales.

Conversion Formula
The formula to convert kelvin (K) to rankine (°R) is:
°R = K × 1.8
Rankine scale measures absolute temperature like kelvin, but it uses Fahrenheit degrees, which are larger than kelvin degrees. Because 1 kelvin equals 1.8 Fahrenheit degrees, multiplying kelvin by 1.8 converts it into rankine.
For example, converting 125 kelvin:
- Start with 125 K
- Multiply by 1.8: 125 × 1.8 = 225
- Result is 225 °R
Conversion Example
- Convert 200 K to rankine:
- Multiply 200 by 1.8
- 200 × 1.8 = 360 °R
- Convert 50 K to rankine:
- 50 × 1.8 = 90 °R
- Convert 300 K to rankine:
- 300 × 1.8 = 540 °R
- Convert 0 K to rankine:
- 0 × 1.8 = 0 °R

Conversion Definitions
Kelvin: Kelvin is the base unit of temperature in the International System of Units. It measures absolute temperature starting from absolute zero, the point where particles have minimum thermal motion. Kelvin scale increments equal to Celsius degrees but starts at −273.15 °C.
Rankine: Rankine is an absolute temperature scale like kelvin, but based on Fahrenheit degrees. It starts at absolute zero and increases in increments equal to Fahrenheit degrees. Rankine is commonly used in thermodynamics within the United States and engineering fields.
Conversion FAQs
Why does the kelvin to rankine conversion multiply by 1.8?
Since rankine degrees are sized like Fahrenheit degrees, which are 1.8 times larger than kelvin or Celsius degrees, the multiplication by 1.8 adjusts the kelvin temperature to the larger degree units of the rankine scale. Both scales start at absolute zero, so no offset is needed.
Can the conversion result from kelvin to rankine be less than kelvin value?
No, because rankine degrees are larger than kelvin degrees, the rankine value will always be equal to or greater than the kelvin value when converted. The multiplication by 1.8 increases the number, so the rankine value never less than kelvin.
Are kelvin and rankine used in everyday temperature measurements?
Kelvin and rankine are mostly used in scientific and engineering contexts, not daily weather reports. Kelvin is common in physics and chemistry, while rankine is used in some engineering fields in the US. Celsius and Fahrenheit dominate everyday temperature use.
Is there any offset required when converting from kelvin to rankine?
No offset is needed because both kelvin and rankine scales begin at absolute zero. The difference lies only in unit size, so the conversion is a simple multiplication without adding or subtracting a constant.
Can I convert negative kelvin values to rankine?
Negative kelvin values do not exist in physics because kelvin starts at absolute zero, the lowest possible temperature. Therefore, converting a negative kelvin temperature to rankine is not physically meaningful or possible.
