Kelvin is the primary unit of temperature in the International System of Units (SI). The Fahrenheit is the unit of temperature in the Fahrenheit scale. Although it is not used within SI, it is still widely used within the United States and some other countries. The definition of the Fahrenheit scale has changed over the course of history. For most of the 20^th century, the scale was defined as the freezing point of water being 32°F and the boiling point being 212°F, both at sea level and standard atmospheric pressure. Now, it is formally defined based on the Kelvin scale, which in turn is based on the Boltzmann constant.
