Mercury-in-glass thermometer ushered in a new era of accuracy and precision in thermometry, and is still to this day regarded as one of the most accurate thermometers available. The thermometer was used by the originators of the Fahrenheit and Celsius scales. Anders Celsius, a Swedish scientist, devised the Celsius scale, which was described in his publication "The origin of the Celsius temperature scale" in 1742. Celsius used two fixed points in his scale: the temperature of melting ice and the temperature of boiling water. This wasn't a new idea, since Isaac Newton was already working on something similar. The distinction of Celsius
Planck temperature scale can convert it to 192.8 cµy"T". These units are somewhat comparable to that of that of the Kelvin scale. When using cµy"T", 0 is absolute zero, and 1 × 10 is the Planck temperature. 1 × 10 cµy"T" is a perfect base ten number as opposed to 1.417 × 10 K, 1.417 × 10 °C, or 2.550 × 10 °F. Each centimicroyocto plank temperature is equal to one 100 nonillionth of the Planck temperature. Planck temperature scale The Planck temperature scale is an absolute temperature scale using natural units. On this scale, 0 is absolute zero, and 1 is the
