Fahrenheit

Definition: The Fahrenheit (symbol: °F) is a unit of measurement of temperature that was widely used prior to metrication. It is currently defined by two stock-still points: the temperature at which h2o freezes, 32°F, and the boiling point of water, 212°F, both at sea level and standard atmospheric force per unit area. The interval between the freezing and boiling point is divided into 180 equal parts.

History/Origin: The Fahrenheit scale was developed based on a measurement proposed in 1724 by the High german physicist Daniel Gabriel Fahrenheit. He initially based the scale on an equal ice-common salt mixture, selecting the values of 30°F for the freezing point of water, and 90°F for normal torso temperature. He after adjusted the scale such that the melting betoken of ice was 32°F and trunk temperature was 96°F. He chose these values to simplify the degree markings he could make on his instruments, since this deviation betwixt the temperatures allowed him to marker degree lines by bisecting the interval six times. Later, when using the freezing and humid points of water as fixed reference points for thermometers became pop, the scale was slightly re-defined such that there would be 180 degrees separating freezing and boiling point, resulting in normal human body temperature being approximately 98°F, rather than Fahrenheit's 96°F.

Current employ: Until the 1960's the Fahrenheit calibration was the primary scale used in English language-speaking countries. Today, most countries around the globe apply the Celsius temperature scale instead, many having made the change during their metrication processes (conversion to using the metric organization of units). However, the Fahrenheit scale is still used as the official temperature scale in a number of countries, including the Usa (as well as its unincorporated territories), the Bahamas, Belize, the Cayman Islands, and a few others.

Celsius

Definition: The Celsius (symbol: °C) is an SI (International System of Units) derived unit of temperature. It is divers based on the SI unit of temperature, the kelvin. The Celsius and Kelvin scales are precisely related, with a one-degree alter in Celsius beingness equal to a one caste-change in kelvin. The kelvin (and thus Celsius) is defined based on the Boltzmann abiding, k, which equals 1.380649 × ten^-23 when expressed in the unit J·Chiliad^-1, a unit of measurement equivalent to kg·thousandⁱⁱ·s^-ii·K^-i. The kilogram, meter, and 2nd, are defined based on Planck'southward constant, h, the speed of low-cal, c, and cesium frequency, ΔνCs.

History/origin: From 1743 until 1954, the Celsius calibration was based on 0°C for the freezing point of water and 100 °C for the humid point of water, both at a pressure level of one standard atmosphere, using mercury as the working material. This was not ever the case, and originally 0°C was defined as the boiling point of water and 100°C was defined as the melting point of snow. Celsius as a unit of measurement and a scale was not widely used until this original definition was inverted. In 1954, the unit of measurement, "degree Celsius," as well every bit the Celsius scale were again re-defined to instead be based on accented zero (-273.15 °C) and the triple betoken of VSMOW (specially purified water). This is the definition that was used up until 2019, when the kelvin was redefined based on the definitions of the 2nd, meter, and kilogram.

Current employ: The Celsius scale replaced the Fahrenheit calibration in most countries in the mid to late xx^thursday century. Almost all countries effectually the world use this scale, except for those in which the metric system has not been adopted, such every bit the United States. Even in countries like the United States yet, Celsius is widely used within the scientific customs—it just is not widely used in everyday temperature references.
