Kelvin is a unit of temperature in the International System of Units (SI). It is the base unit of temperature in the SI system and is defined as 1/273.16 of the thermodynamic temperature of the triple point of water. The symbol for Kelvin is K.
Celsius, often abbreviated as °C, is a unit of temperature measurement in the metric system. It is named after the Swedish astronomer Anders Celsius, who developed the Celsius temperature scale in 1742.
Fahrenheit is another unit of temperature measurement, primarily used in the United States and a few other countries. It is denoted by the symbol °F. On the Fahrenheit scale, the freezing point of water is 32 degrees Fahrenheit (°F), and the boiling point of water is 212 degrees Fahrenheit (°F) at standard atmospheric pressure. The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in the early 18th century.
