That is the usual spelling Kelvin for the name or surname.It is seen in lowercase for the degree interval on the temperature scale named for Lord Kelvin (kelvins or K).
340 Kelvins are equal to 152.6 degrees Fahrenheit.
0 degrees Celsius = 273.15 Kelvins
Radioactive decay particularily from the isotopes of Uranium, thorium and Potassium. The discovery of this was Lord Rutherfords solution to Lord Kelvins estimation that the earth was only 20 thousand years old.
4 kelvins = -452.47 degrees Fahrenheit.[°F] = [K] × 9⁄5 − 459.67
351.15 kelvins
Among many other inventions, Lord Kelvin is most famous for having introduced the Kelvin temperature scale that is based on absolute zero (-273.15°C).
Add 273.15 to the number of Celsius degrees to get the same temperature in Kelvins.
