1714 — Daniel Gabriel Fahrenheit invents the mercury-in-glass thermometer giving much greater precision (4 x that of Rømer). Using Rømer's zero point and an upper point of blood temperature, he adjusted the scale so the melting point of ice was 32 and the upper point 96, meaning that the difference of 64 could be got by dividing the ...
Thermometer with Fahrenheit (symbol °F) and Celsius (symbol °C) units. In 1714, scientist and inventor Daniel Gabriel Fahrenheit invented a reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724, he proposed a temperature scale which now (slightly adjusted) bears his name.

The second reference point was selected as the reading of the thermometer when it was placed in still water when ice was just forming on the surface. [15] This was assigned as 30 °F. The third calibration point, taken as 90 °F, was selected as the thermometer's reading when the instrument was placed under the arm or in the mouth. [16]

The first sealed thermometer was constructed in 1654 by the Grand Duke of Tuscany, Ferdinand II. [1]: 19 The development of today's thermometers and temperature scales began in the early 18th century, when Daniel Gabriel Fahrenheit produced a mercury thermometer and scale, both developed by Ole Christensen Rømer.
