Temperature Converter
Celsius, Fahrenheit and Kelvin.
1 degree Fahrenheit = 255.9277778 K. Enter any value to convert degrees Fahrenheit (°F) to kelvins (K), or use the table below for common values.
K = °F × 0.5555555556 + 255.3722222
Example: 100 °F = 310.9277778 K. To convert the other way, use °F = K × 1.8 − 459.67.

On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F. It remains the everyday temperature scale in the United States.
The kelvin is the SI unit of temperature. 0 K is absolute zero, and one kelvin step equals one degree Celsius, so K = °C + 273.15.
Use the formula K = °F × 0.5555555556 + 255.3722222. For example, 100 °F = 310.9277778 K.
1 °F = 255.9277778 K.
Use °F = K × 1.8 − 459.67. 1 K = -457.87 °F.
