Temperature Conversion Table and Online Calculation
| From | To Fahrenheit | To Celsius |
|---|---|---|
| Fahrenheit (F) | F | (F – 32) * 5/9 |
| Celsius (C or o) | (C * 9/5) + 32 | C |
| Kelvin (K) | (K – 273.15) * 9/5 + 32 | K – 273.15 |
Fahrenheit (symbol °F) is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736), after whom the scale is named. On Fahrenheit’s original scale the lower defining point was the lowest temperature to which he could reproducibly cool brine (defining 0 degrees), while the highest was that of the average human core body temperature (defining 100 degrees). There exist several stories on the exact original definition of his scale; however, some of the specifics have been presumed lost or exaggerated with time. The scale is now usually defined by two fixed points: the temperature at which water freezes into ice is defined as 32 degrees, and the boiling point of water is defined to be 212 degrees, a 180 degree separation, as defined at sea level and standard atmospheric pressure.
