Fahrenheit Scale - Daniel Gabriel Fahrenheit
What can be considered the first modern thermometer, the mercury thermometer
with a standardized scale, was invented by Daniel Gabriel Fahrenheit in 1714.
Daniel Gabriel Fahrenheit was the German physicist who invented a alcohol
thermometer in 1709, and the mercury thermometer in 1714.
In 1724, he introduced the standard temperature scale that bears his name -
Fahrenheit Scale - that was used to record changes in temperature in an
accurate fashion.
The Fahrenheit scale divided the freezing and boiling points of water into
180 degrees. 32°F was the freezing point of water and 212°F was the boiling
point of water. 0°F was based on the temperature of an equal mixture of water,
ice, and salt. Fahrenheit based his temperature scale on the temperature of
the human body. Originally, the human body temperature was 100° F on the
Fahrenheit scale, but it has since been adjusted to 98.6°F.
