Fahrenheit invented the mercury thermometer in 1714, but it is unknown exactly how many he made. It divided the freezing and boiling points of water into 180 degrees. 32Â°F was the freezing point of water and 212Â°F was the boiling point of water, set by Fahrenheit himself. 0Â°F was based on the temperature of an equal mixture of water, ice, and salt. Fahrenheit based his scale on the temperature of the human body.
In 1848, Lord Kelvin wrote in his paper, On an Absolute Thermometric Scale, of the need for a scale whereby infinite cold (absolute zero) was the scale's null point, and which used the degree Celsius for its unit increment.he kelvin is defined as the fraction 1â273.16 of the thermodynamic temperature of the triple point of water (exactly 0.01 Â°C or 32.018 Â°F). In other words, it is defined such that the triple point of water is exactly 273.16 K.
