Fahrenheit to KelvinConverter
Instantly convert Fahrenheit (°F) to Kelvin (K). Free, accurate, and easy to use.
What is a Fahrenheit?
The Fahrenheit scale is used primarily in the United States for everyday temperature, with water freezing at 32 °F and boiling at 212 °F at standard pressure. It was proposed by German physicist Daniel Gabriel Fahrenheit in 1724, using brine, melting ice, and approximate body temperature as reference points. Because a Fahrenheit degree is 5/9 the size of a Celsius degree, Fahrenheit gives finer resolution for typical ambient temperatures. Normal human body temperature is approximately 98.6 °F (37 °C).
What is a Kelvin?
The Kelvin is the SI base unit of thermodynamic temperature, with its zero point at absolute zero — the coldest theoretically possible temperature, −273.15 °C or −459.67 °F. It was proposed by physicist William Thomson (Lord Kelvin) in 1848. Each Kelvin degree is the same size as a Celsius degree; to convert, add 273.15. The Kelvin scale is essential in physics, chemistry, and astronomy because it eliminates negative values. The surface temperature of the Sun is approximately 5,778 K.
