This video is called "What The Fahrenheit?!"
It basically tells you about the history of how fahrenheit came about and the queries about some of the temperature like 0℉ and a bit about the character of Daniel Gabriel Fahrenheit.
What I have learnt from this video clip:
- Daniel Gabriel adopted a temperature scale from an astronomer in 1708
- The freezing point of water is 32℉.
- As an instrument maker, Fahrenheit was very secretive about his method.
