# Fahrenheit conversion formulas

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

## Fahrenheit to Celsius formula

Formula for converting from degrees Fahrenheit (°F) to degrees Celsius (°C) is:

T(°C) = [T(°F) - 32] × 5/9

How to convert 45 degrees Fahrenheit (°F) to degrees Celsius (°C)?

Substitute T(°F) in the Fahrenheit to Celsius formula for 45 and make the calculation.

T(°C) = [45 - 32] × 5/9

T(°C) = 7.2222 or

45 °F = 7.2222 °C

45 degrees Fahrenheit (°F) equals 7.2222 degrees Celsius (°C).

## Fahrenheit to Kelvin formula

Formula for converting from degrees Fahrenheit (°F) to kelvin (K) is:

T(K) = [T(°F) + 459.67] × 5/9

How to convert 35 degrees Fahrenheit (°F) to kelvin (K)?

Substitute T(°F) in the Fahrenheit to Kelvin formula for 35 and make the calculation.

T(K) = [35 + 459.67] × 5/9

T(K) = 274.8167 or

35 °F = 274.8167 K

35 degrees Fahrenheit (°F) equals 274.8167 kelvin (K).

## Fahrenheit to Réaumur formula

Formula for converting degrees Fahrenheit (°F) to degrees Réaumur (°Ré) is:

T(°Ré) = [T(°F) - 32] × 4/9

How to convert 40 degrees Fahrenheit (°F) to degrees Réaumur (°Ré)?

Substitute T(°F) in the Fahrenheit to Réaumur formula for 40 and then make the calculation.

T(°Ré) = [40 - 32] × 4/9

T(°Ré) = 3.5556 or

40 °F = 3.5556 °Ré

40 degrees Fahrenheit (°F) equals 3.5556 degrees Réaumur (°Ré).

## Fahrenheit to Rankine formula

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

T(°R) = T(°F) + 459.67

How to convert 48 degrees Fahrenheit (°F) to degrees Rankine (°R)?

Substitute T(°F) in the Fahrenheit to Rankine formula for 48 and make the calculation.

T(°R) = 48 + 459.67

T(°R) = 507.67 or

48 °F = 507.67 °R

48 degrees Fahrenheit (°F) equals 507.67 degrees Rankine (°R).
