## Rankine to Celsius conversion calculator

Enter the temperature in degrees Rankine and press the *Convert* button:

#### Rankine to Celsius

Rankine to Celsius converter above calculates how many Celsius are in 'X' Rankine (where 'X' is the number of Rankine to convert to Celsius). In order to convert a value from Rankine to Celsius (from °R to °C) simply type the number of °R to be converted to °C and then click on the 'convert' button.

Convert degrees Rankine to degrees Celsius with this simple formula:

degrees Celsius = ( [°R] - 491.67 ) × 5 / 9

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

#### For example

let's convert 50 °R to degrees Celsius:

50 °R = ( ( 50 - 491.67 ) × 5 / 9 ) = -245.372222 °C

The Rankine scale and the Celsius scale are both used to measure temperature. Read on to learn more about each of them.

#### 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.

#### Important Temperatures In Degrees Rankine

Temperature | Degrees Rankine |
---|---|

Absolute Zero | 0 °R |

Freezing Point of Water | 491.67 °R |

Triple Point of Water | 491.688 °R |

Boiling Point of Water | 671.67 °R |

#### Celsius

The Celsius temperature scale, also commonly referred to as the centigrade scale, is defined in relation to the kelvin. Specifically, degrees Celsius is equal to kelvins minus 273.15.

The degree Celsius is the SI derived unit for temperature in the metric system. A degree Celsius is sometimes also referred to as a degree centigrade. Celsius can be abbreviated as C; for example, 1 degree Celsius can be written as 1 °C.

#### Important Temperatures In Degrees Celsius

Temperature | Degrees Celsius |
---|---|

Absolute Zero | -273.15 °C |

Freezing Point of Water | 0 °C |

Triple Point of Water | 0.01 °C |

Boiling Point of Water | 100 °C |
