# How to convert a temperature to Rankine

Formulas to convert a unit of temperature to degrees Rankine

## Formula to convert Fahrenheit to Rankine

Formula to convert from degrees Fahrenheit (°F) to degrees Rankine (°R) is:

T(°R) = T(°F) + 459.67

How many degrees Rankine (°R) correspond to 45 degrees Fahrenheit (°F)?

Replace T(°F) in the °F to °R formula for 45 and add 459.67.

T(°R) = 45 + 459.67

T(°R) = 504.67 or

45 °F = 504.67 °R

45 degrees Fahrenheit correspond to 504.67 degrees Rankine.

## Formula to convert Celsius to Rankine

Formula for converting from degrees Celsius (°C) to degrees Rankine (°R) is:

T(°R) = [T(°C) + 273.15] × 9/5

How many degrees Rankine (°R) correspond to 65 degrees Celsius (°C)?

Replace T(°C) in the °C to °R formula for 65, add 273.15, multiply by 9, then divide by 5.

T(°R) = [65 + 273.15] × 9/5

T(°R) = 608.67 or

65 °C = 608.67 °R

65 degrees Celsius correspond to 608.67 degrees Rankine.

## Formula to convert Kelvin to Rankine

Formula for converting from kelvin (K) to degrees Rankine (°R) is:

T(°R) = T(K) × 9/5

How many degrees Rankine (°R) correspond to 150 kelvins (K)?

Replace T(K) in the K to °R formula for 150, multiply by 9, then divide by 5.

T(°R) = 150 × 9/5

T(°R) = 270 or

150 K = 270 °R

150 kelvins correspond to 270 degrees Rankine.

## Formula to convert Réaumur to Rankine

Formula for converting from degrees Réaumur (°Ré) to degrees Rankine (°R) is:

T(°R) = T(°Ré) × 9/4 + 491.67

How many degrees Rankine (°R) correspond to 35 degrees Réaumur (°Ré)?

Replace T(°Ré) in the °Ré to °R formula for 35, multiply by 9, divide by 4, then add 491.67.

T(°R) = 35 × 9/4 + 491.67

T(°R) = 570.42 or

35 °Ré = 570.42 °R

35 degrees Réaumur correspond to 570.42 degrees Rankine.
