Fahrenheit to Kelvin
About these units
Fahrenheit
Fahrenheit (°F) places water's freezing point at 32° and boiling point at 212°. It is the standard scale for weather and cooking in the United States.
Kelvin
The kelvin is the SI base unit of temperature, starting at absolute zero (0 K = −273.15 °C), the coldest possible temperature. It uses the same step size as Celsius.
Conversion formula
Temperature scales differ by both a zero point and a step size, so conversion uses a formula rather than a single factor: °F = (°C × 9/5) + 32, and K = °C + 273.15.
