单词 Fahrenheit scale
释义
Fahrenheit scale

Physics
  • A temperature scale in which (by modern definition) the temperature of boiling water is taken as 212° and the temperature of melting ice as 32°. It was invented in 1714 by G. D. Fahrenheit, who set the zero at the lowest temperature he knew how to obtain in the laboratory (by mixing ice and common salt) and took his own body temperature as 96°F. The scale is no longer in scientific use. To convert to the Celsius scale the formula is C=5(F−32)/9.


Chemistry
  • A temperature scale in which (by modern definition) the temperature of boiling water is taken as 212 degrees and the temperature of melting ice as 32 degrees. It was invented in 1714 by G. D. Fahrenheit, who set the zero at the lowest temperature he knew how to obtain in the laboratory (by mixing ice and common salt) and took his own body temperature as 96°F. The scale is no longer in scientific use. To convert to the Celsius scale the formula is C = 5(F – 32)/9.


Chemical Engineering
  • A temperature scale invented in 1714 by German physicist and instrument-maker Gabriel Daniel Fahrenheit (1686–1736). Fahrenheit was the first person to make practical thermometers using mercury instead of spirits of wine (alcohol). He calibrated his thermometer between two fixed points for which he used the eutectic point of salt water as 0°, which was the lowest temperature he could obtain in the laboratory, and the temperature of a healthy human which he originally called 12° and later 96°. He found that on his scale, pure ice melted at 32°F and steam at normal atmospheric pressure was 212°F. The conversion to the Celsius scale is given by:

    °C=59(°F32)

  • A temperature scale in which (by modern definition) the temperature of boiling water is taken as 212 degrees and the temperature of melting ice as 32 degrees. It was invented in 1714 by the German scientist G. D.

    C=5(F32)/9.
