How hot is it? Twenty. Twenty what?
Thanks to the U.S. school system, I never learned anything to do with the metric system. So when I travel the world, I have to tough time figuring out: How hot or cold it is, how fast I'm going, how far something is etc. So to help out, I created a little Temperature Conversion infographic 'cheat sheet'
The degree Fahrenheit (°F) is a unit of temperature named for the german physicist Gabriel Fahrenheit (1686 - 1736). In the Fahrenheit scale of temperature the freezing point of water is 32 degrees and the boiling point is 212 degrees placing the boiling and melting points of water 180 degrees apart. Zero degrees Fahrenheit indicates the lowest temperature Fahrenheit could obtain by a mixture of ice and salt.
