Fahrenheit to Celsius, Kelvin, Rankine, and Reaumur formulas and how to convert

Fahrenheit to Celsius formula and how to convert

Formula to convert Fahrenheit to Celsius (°F to °C) is:

T(°C) = [T(°F) - 32] × 5/9

So, to convert Fahrenheit to Celsius, subtract 32 from the temperature in degrees Fahrenheit T(°F), multiply the result by 5 and then divide by 9.

Example

How to convert 100 Fahrenheit to Celsius (°F to °C)?

To convert 100 Fahrenheit to Celsius, substitute T(°F) in the Fahrenheit to Celsius formula for 100 and make the calculation.

T(°C) = [100 - 32] × 5/9 = 68 × 5/9 = 37.78

T(°C) = 37.78 or

100 °F = 37.78 °C

100 degrees Fahrenheit (°F) are equal to 37.78 degrees Celsius (°C).

(or, 100 Fahrenheit to Celsius is 37.78°C)

Fahrenheit to Kelvin formula and how to convert

Formula to convert Fahrenheit to kelvin (°F to K) is:

T(K) = [T(°F) + 459.67] × 5/9

So, to convert Fahrenheit to kelvin add 459.67 to the temperature in degrees Fahrenheit T(°F), multiply the result by 5, and then divide by 9.

Example

How to convert 100 Fahrenheit to kelvin (°F to K)?

To convert 100 Fahrenheit to kelvin, substitute T(°F) in the Fahrenheit to Kelvin formula for 100 and make the calculation.

T(K) = [100 + 459.67] × 5/9 = 559.67 × 5/9 = 310.93

T(K) = 310.93 or

100 °F = 310.93 K

100 degrees Fahrenheit (°F) are equal to 310.93 kelvin (K).

(or, 100 Fahrenheit to kelvin is 310.93K)

Fahrenheit to Rankine formula and how to convert

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

T(°R) = T(°F) + 459.67

Thus, to convert Fahrenheit to Rankine, add 459.67 to the temperature in degrees Fahrenheit T(°F).

Example

How to convert 100 Fahrenheit to Rankine (°F to °R)?

Substitute T(°F) in the Fahrenheit to Rankine formula for 100 and make the calculation.

T(°R) = 100 + 459.67 = 559.67

T(°R) = 559.67 or

100 °F = 559.67 °R

100 degrees Fahrenheit (°F) are equal to 559.67 degrees Rankine (°R).

Fahrenheit to Réaumur formula and how to convert

Formula to convert Fahrenheit to Réaumur (°F to °Ré) is:

T(°Ré) = [T(°F) - 32] × 4/9

Thus, to convert Fahrenheit to Réaumur subtract 32 from the temperature in degrees Fahrenheit T(°F), multiply the result by 4, and then divide by 9.

Example

How to convert 100 Fahrenheit to Réaumur (°F to °Ré)?

Substitute T(°F) in the Fahrenheit to Réaumur formula for 100 and then make the calculation.

T(°Ré) = [100 - 32] × 4/9= 68 × 4/9 = 30.22

T(°Ré) = 30.22 or

100 °F = 30.22 °Ré

100 degrees Fahrenheit (°F) are equal to 30.22 degrees Réaumur (°Ré).
