Degree Fahrenheit to Kelvin conversion

1 °F ≈ 255.9277778 Kone degree Fahrenheit in kelvins

1 K = -457.87 °Fone kelvin in degrees Fahrenheit

Degree Fahrenheit (°F): 5/9 of a kelvin; 0 °F is exactly 459.67 °R above absolute zero, so K = (°F + 459.67) × 5/9.

Kelvin (K): SI base unit of thermodynamic temperature, defined by fixing the Boltzmann constant k = 1.380649e-23 J/K.

How to convert degrees Fahrenheit to kelvins

To convert degrees Fahrenheit to kelvins, add 459.67, then divide by 1.8.

Formula

K = (°F + 459.67) ÷ 1.8

Examples

  • 32 °F = (32 + 459.67) ÷ 1.8 = 273.15 K
  • 72 °F = (72 + 459.67) ÷ 1.8 ≈ 295.3722222 K
  • 212 °F = (212 + 459.67) ÷ 1.8 = 373.15 K
