About these units
Fahrenheit (°F). The Fahrenheit scale sets water's freezing point at 32° and boiling point at 212°. It is the everyday temperature scale in the United States and a few other countries.
Kelvin (K). The kelvin is the SI base unit of temperature, starting at absolute zero (−273.15 °C), the point where thermal motion stops. It is used in physics, chemistry and engineering.
