Convert degrees Fahrenheit (°F) to kelvins (K) instantly — type a value below.
Temperature scales do not share the same zero point, so you cannot simply multiply. Use this formula:
K = (°F − 32) × 5/9 + 273.15

On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F. It is used for weather, cooking and body temperature mainly in the United States.
The kelvin is the SI base unit of temperature. 0 K is absolute zero, and a change of 1 K equals a change of 1 °C. It is used in science and engineering.
