StampNews.com is glad to inform that German Post is ready to introduce a special postage stamp marking 300 years of creating the Fahrenheit scale. The stamp has been already designed and is to be issued on the 3d of November. Fahrenheit is a temperature scale used mostly in the USA. It was introduced almost 300 years ago by a German scientist called Daniel Gabrial Fahrenheit.
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.
