Fahrenheit established 0ºF as the stabilized temperature when equal amounts of ice, water, and salt are mixed. He then defined 96ºF as the temperature 'when the thermometer is held in the mouth or under the armpit of a living man in good health'.
0ºC and 100ºC are arbitrarily placed at the melting and boiling points of water and standard to the metric system
