How warm is it today?

May 24, 1686 –

Gabriel Fahrenheit was born on the date. Mr Fahrenheit did pioneering work in the field of temperature. It was his dream to develop a more sophisticated temperature measurement system than the accepted worldwide standard of his era, which consisted of only seven gradations: brr!, cold as hell, chilly, warm, hot, hotter than hell and ow!.

Hard at work on the same problem was his colleague Anders Celsius. Mr Fahrenheit eventually discovered the “degree.” It took 32 of Mr Fahrenheit’s degrees to freeze water and 212 of them to boil it. Mr Celsius, meanwhile, had discovered a different kind of “degree.”

It took only a hundred of his degrees to bring water to a boil, and, even more impressively, he discovered that water would freeze without any degrees at all.

By requiring fewer degrees to get things done, and less tick marks on thermometers, Mr Celsius’s system was more compact and economical than Mr Fahrenheit’s. This made it a natural for the crowded lands of Europe, where storage came at a premium. In the great unsettled expanse of the New World, however, space was not an issue and Mr Fahrenheit’s system took hold.

And so it goes
