Fahrenheit (F) is a unit of temperature measurement, named after its inventor, German Gabriel Danielfahrenheit (1686-1736). 1724, he found that liquid metal mercury was more suitable for making thermometers than alcohol. He invented the glass mercury thermometer with mercury as the temperature measuring medium. The freezing point of the mixture of ammonium chloride and ice water is chosen as the zero degree of thermometer, and the human body temperature is 100 degrees. At standard atmospheric pressure, the melting point of ice is 32℉, the boiling point of water is 2 12℉, and there are 180 equal parts in the middle, and each equal part is 1 Fahrenheit, which is recorded as "1℉".
