华氏温标是一种温标，符号为℉ 或 °F。华氏温标的定义是：在标准大气压下，冰的熔点为32℉，水的沸点为212℉，中间有180等分，每等分为华氏1度。

根据德国科学家华伦海特于1724年所写的一篇期刊，他使用三个参考温度来标示他的刻度。将温度计放入由冰、水以及氯化铵所混合而成的盐水中，量得的刻度即为零度，因为这是当时能制造出最低温度的物品。盐水是一种制冷混合物，可以将温度自动维持在华氏零度。第二个刻度是32度，为将温度计放恰好有冰形成于表面的水中所量得的刻度。第三个刻度为96度，为将温度计照含入口中，或夹在腋下时所量得的刻度。华伦海特表示，使用此一刻度，水银约在600度时沸腾。

Fahrenheit is a temperature scale based on one proposed in 1724 by the German physicist Daniel Gabriel Fahrenheit (1686–1736), after whom the scale is named. It uses the degree Fahrenheit (symbol °F) as the unit. There exist several accounts of how he originally defined his scale. The lower defining point, 0 degrees, was established as the temperature of a solution of brine made from equal parts of ice and salt. Further limits were established as the melting point of ice (32 degrees) and his best estimate of the average human body temperature (96 degrees, about 2.5 degrees less than modern measurements). The scale is now usually defined by two fixed points: the temperature at which water freezes into ice is defined as 32 degrees, and the boiling point of water is defined to be 212 degrees, a 180-degree separation, as defined at sea level and standard atmospheric pressure.
