Daniel Gabriel Fahrenheit temperature scale to be widely used). In other words, Fahrenheit's inventions ushered in the first revolution in the history of thermometry (branch of physics concerned with methods of temperature measurement). From the early 1710s until the beginnings of the electronic era, mercury-in-glass thermometers were among the most reliable and accurate thermometers ever invented. Fahrenheit was born in the city of Danzig (Gdańsk), Pomeranian Voivodeship in the Polish–Lithuanian Commonwealth, but lived most of his life in the Dutch Republic.

One of its users was Mikhail Lomonosov, who reversed it, as Jean-Pierre Christin did with Celsius' scale, making the freezing point of water 0 °D and the boiling point 150 °D. Delisle scale The Delisle scale (°D) is a temperature scale invented in 1732 by the French astronomer Joseph-Nicolas Delisle (1688–1768). Delisle was the author of "Mémoires pour servir à l'histoire et aux progrès de l'Astronomie, de la Géographie et de la Physique" (1738). In 1732, Delisle built a thermometer that used mercury
