- unit of the temperature of which the scale is defined by two fixe-points, the temperatures of freezing point (32 °F) and boiling point (212 °F) of water at normal pressure (air pressure of 1 013,25 hPa)
- Note
- For the numerical value of Fahrenheit temperature and the accordant thermodynamic temperature the following relation is valid: - for absolute temperature: {δ}Fahrenheit = {T}Kelvin • 1,8 - 459,67 - for temperature differences: {Δδ}Fahrenheit = {ΔT}Kelvin • 1,8
