#### Kelvin to Rankine

A ºF version of the Kelvin scale. Based upon the definitions of the Fahrenheit scale and the experimental evidence that absolute zero is -459.67ºF. Based upon the definitions of the Centigrade scale and the experimental evidence that absolute zero is -273.15ºC

Convert kelvins to degrees Rankine with this simple formula:

degrees Rankine = [K] × 9 / 5

Insert the [K] temperature measurement in the formula and then solve to find the result.

#### For example

let's convert 50 K to degrees Rankine:

50 K = ( 50 × 9 / 5 ) = 90 °R

Kelvins and the Rankine scale are both used to measure temperature.

#### Kelvins

The Kelvin scale is an absolute temperature scale that uses absolute zero as the starting point. The kelvin is defined in terms of the Boltzmann constant, which is a measure of the energy of motion corresponding to one kelvin.

More specifically, one kelvin is equal to the change of thermodynamic temperature that results in a change of thermal energy kT by 1.380649 × 10^{−23} J.

0 kelvins are equal to −273.15 degrees Celsius, which is the point of absolute zero.

The kelvin is the SI base unit for temperature in the metric system. Kelvins can be abbreviated as K; for example, 1 kelvin can be written as 1 K.

The kelvin scale is different from other temperature scales in that it is not expressed in degrees, values are expressed in kelvins. When using the Kelvin scale in writing, the "k" is capitalized, however when using the kelvin as a unit the "k" should be lower-case, even though it is named for a person.

#### Important Temperatures In Kelvins

Temperature | Kelvins |
---|---|

Absolute Zero | 0 K |

Freezing Point of Water | 273.15 K |

Triple Point of Water | 273.16 K |

Boiling Point of Water | 373.15 K |

#### Rankine

The Rankine scale is an absolute temperature scale that uses absolute zero as the starting point, much like the Kelvin scale. The key difference between the Rankine scale and the Kelvin scale is that an increment of one degree rankine is equal to an increment of one degree Fahrenheit, not Celsius as in the Kelvin scale. The base of the Rankine scale starts at absolute zero, thus 0 degrees rankine are equal to −459.67 degrees Fahrenheit.

Rankine can be abbreviated as R, and are also sometimes abbreviated as Ra. For example, 1 degree Rankine can be written as 1 °R or 1 Ra.
