Convert Fahrenheit to Kelvin

The Fahrenheit scale was developed by the German physicist Daniel Gabriel Fahrenheit in the early 18th century, specifically in 1724. Fahrenheit chose 32°F as the freezing point of water and 212°F as the boiling point of water under normal atmospheric pressure. The scale was based on several reference points, including the freezing point of water, the temperature of a mixture of ice and salt (which he set to 0°F), and the human body temperature, which he initially set at 96°F (later adjusted to 98.6°F). The Fahrenheit scale was widely used in English-speaking countries, particularly the U.S., until the adoption of the Celsius and Kelvin scales in scientific communities. It remains in common use for everyday temperature measurements in the U.S. and some Caribbean nations.

The Kelvin scale was developed by the British physicist William Thomson, later known as Lord Kelvin, in the 1840s. Lord Kelvin proposed the concept of an absolute temperature scale, where zero would correspond to the complete absence of thermal energy (absolute zero). This scale was based on the idea that temperature could be measured starting from an absolute minimum, rather than from the freezing point of water. The Kelvin scale is widely used in scientific fields, especially in thermodynamics, physics, and chemistry, because it provides a consistent and absolute reference for temperature measurements.
