Celsius or Fahrenheit
Gosh its hot out there
Of late we have been watching CNN International.
It has weather breaks with world temperatures in Celsius.
Which raised the question how many countries officially use Fahrenheit?
According to Wikipedia,
The Fahrenheit scale was the primary temperature standard for climatic, industrial and medical purposes in English-speaking countries until the 1960s. In the late 1960s and 1970s, the Celsius scale replaced Fahrenheit in almost all of those countries—with the notable exception of the United States—typically during their general metrication process.
Fahrenheit is used in the United States, its territories and associated states (all served by the U.S. National Weather Service), as well as the Cayman Islands and Liberia for everyday applications.
So that is about it.
US, Liberia and the Caymans.
It is important to note, the temperature of a body in its own state of thermodynamic equilibrium is always positive, relative to the absolute zero.
When its hot, its hot.
