Celsius: The Celsius scale, also known as the centigrade scale, is a temperature scale widely used in most of the world. It was named after the Swedish astronomer Anders Celsius, who first proposed a similar system in 1742. The Celsius scale sets the freezing point of water at 0 degrees and the boiling point of water at 100 degrees under standard atmospheric pressure. The Celsius scale is used for everyday temperature measurements, as well as in scientific research.

Fahrenheit: The Fahrenheit scale is a temperature scale used primarily in the United States and its territories. It was created by Daniel Gabriel Fahrenheit, a German physicist and engineer, in 1724. In the Fahrenheit scale, the freezing point of water is set at 32 degrees, and the boiling point of water is set at 212 degrees under standard atmospheric pressure. The Fahrenheit scale is commonly used for weather forecasts, cooking, and heating and cooling systems in the United States.

Kelvin: The Kelvin scale is an absolute temperature scale used primarily in scientific research and engineering. It was named after the Scottish physicist and engineer William Thomson, 1st Baron Kelvin, who contributed significantly to the development of thermodynamics. In the Kelvin scale, zero Kelvin represents absolute zero, the lowest possible temperature at which all molecular motion ceases. The Kelvin scale does not use the term "degrees," and its increments are the same as those of the Celsius scale. The Kelvin scale is widely used in physics, chemistry, and engineering to measure extremely low or high temperatures.
