K = (F − 32) × 5/9 + 273.15
0 °F equals 255.372 K.
100 °F equals 310.928 K.
F = (K − 273.15) × 9/5 + 32
32 °F (water freezing) equals 273.15 K.
Yes. The conversion between Fahrenheit and Kelvin is defined exactly by international agreement.
The degree Fahrenheit (symbol °F) is the everyday temperature scale used in the United States. Water freezes at 32 °F and boils at 212 °F at standard atmospheric pressure.
The kelvin (symbol K, with no degree sign) is the SI base unit of thermodynamic temperature. 0 K is absolute zero; one kelvin equals one degree Celsius in size.
