# Rankine conversion formulas

Conversion formulas from Rankine to Fahrenheit, Celsius, Kelvin, and Réaumur.

## Rankine to Fahrenheit formula

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

T(°F) = T(°R) - 459.67

How to convert 40 degrees Rankine (°R) to degrees Fahrenheit (°F)?

Substitute T(°R) in the Rankine to Fahrenheit formula for 40 and make the calculation.

T(°F) = 40 - 459.67

T(°F) = -419.67 or

40 °R = -419.67 °F

40 degrees Rankine (°R) equals -419.67 degrees Fahrenheit (°F).

## Rankine to Celsius formula

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

T(°C) = [T(°R) - 491.67] × 5/9

How to convert 35 degrees Rankine (°R) to degrees Celsius (°C)?

Substitute T(°R) in the Rankine to Celsius formula for 35 and make the calculation.

T(°C) = [35 - 491.67] × 5/9

T(°C) = -253.7056 or

35 °R = -253.7056 °C

35 degrees Rankine (°R) equals -253.7056 degrees Celsius (°C).

## Rankine to Kelvin formula

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

T(K) = T(°R) × 5/9

How to convert 45 degrees Rankine (°R) to kelvin (K)?

Substitute T(°R) in the Rankine to Kelvin formula for 45 and make the calculation.

T(K) = 45 × 5/9

T(K) = 25 or

45 °R = 25 K

45 degrees Rankine (°R) equals 25 kelvin (K).

## Rankine to Réaumur formula

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

T(°Ré) = [T(°R) - 491.67] × 4/9

How to convert 42 degrees Rankine (°R) to degrees Réaumur (°Ré)?

Substitute T(°R) in the Rankine to Réaumur formula for 42 and make the calculation.

T(°Ré) = [42 - 491.67] × 4/9

T(°Ré) = -199.8533 or

42 °R = -199.8533 °Ré

42 degrees Rankine (°R) equals -199.8533 degrees Réaumur (°Ré).
