The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 °C or more. Clinical thermometers and many electronic thermometers are usually readable to 0.1 °C. Special instruments can give readings to one thousandth of a degree. However, this p… http://boson.physics.sc.edu/~rjones/phys101/Fahrenheit

WebThe polymath Isaac Newton (1643-1724) used linseed oil in his sealed-in-glass thermometers. His scale used three fixed-points: the temperature of air when water begins to freeze, the heat of blood in the human body and rapidly boiling water.
