About Fahrenheit and Kelvin
Temperature scales describe thermal state. Celsius and Fahrenheit use different zero points and degree sizes, while kelvin is an absolute thermodynamic scale beginning at absolute zero. Fahrenheit is a temperature scale related to Celsius by the exact formula °F = °C × 9/5 + 32. The kelvin is the SI base unit of thermodynamic temperature; 0 K is absolute zero and one kelvin has the same interval size as one Celsius degree.
