The other set limit was its best estimation of the mean, originally fixed at 90°F, then 96°F (about 2.6°F less than the modern value due to a later redefinition of the scale ). However, he pointed to an average point of 32°F, which will be set at the temperature of the ice water. Fahrenheit scaledegree Fahrenheit ° F The Fahrenheit scale is now generally defined by two fixed points: the temperature to which it is purely frozen is defined as 32 °F and the water boiling point is defined as 212 °F, both at and below (a separation of 180 °F). In the first decades of the 18th century in the , Daniel Fahrenheit made two revolutionary advances in the history of . He invented the scale (first thermometer of wide, precise, practical use) and Fahrenheit. Fahrenheit has been the first standardized temperature scale that is widely used, although its use is now limited. It is the official temperature scale in the (including its ), its in the Western Pacific (, and the ), the , and . Fahrenheit is used next to the scale in and other countries that use the same service, such as , the , and . A handful of still use both scales, including , , and . In United Kingdom newspapers, Fahrenheit figures are sometimes used in headlines for heat waves. All other countries of the world officially use the Celsius scale, the name given to the centigrade scale in 1948 in honor of . ContentDefinition and Conversion[] Fahrenheit temperature conversion formula of Fahrenheit a Fahrenheit [°C] = ([°F] - 32) × 5⁄9 [°F] = [°C] × 9⁄5 + 32 [K] = ([°F] + 459.67) × 5⁄9 [°F] = [K] × 9⁄5 − 459.67 [°R] = [°F] + 459.67 [°F] = [°R] - 459.67 For temperature intervals instead of specific temperatures,1 °F = 1 °R = 5⁄9 °C = 5⁄9 K On the Fahrenheit scale, the 32°F and the 212°F (a ). This puts boiling points and freezing water 180 degrees apart. Therefore, a degree in the Fahrenheit scale is 1⁄180 of the interval between the freezing point and the boiling point. On the Celsius scale, the freezing and boiling water points are 100 degrees away. A temperature range of 1 °F is equal to a 5⁄9 degrees Celsius. The Fahrenheit and Celsius scales are intersected to −40° (i.e. −40 °F = −40 °C). is −273.15 °C or −459.67 °F. The use grade intervals of the same size as those of the Fahrenheit scale, except that the absolute zero is 0 °R - in the same way that the temperature scale matches the Celsius scale, except that the absolute zero is 0 K. The degree symbol combination followed by a superior letter F is the conventional symbol for the Fahrenheit temperature scale. A number followed by this symbol (and separated from it with a space) denotes a specific temperature point (e.g., "reforce to 85.5763 °F"), a difference between temperatures (e.g., "The heat exchanger output experiences a rise of 72 °F") or uncertainty in temperature (e.g. "Our standard uncertainty is ±5 °F"). The Celsius scale symbol also uses the grade symbol but with a top letter C ("°C"), while the Kelvin scale symbol is only a top letter K ("K"). The numerical value of a temperature difference or temperature interval is the same when expressed in Celsius or kelvin degrees. Conversion (specific temperature point)[ ]For an exact conversion between Fahrenheit and Celsius of a specific temperature point, the following formulas can be applied. Here, f is the value in Fahrenheit and c the value in Celsius: There is also an exact conversion that makes use of equality −40 °F = −40 °C. Again, f is the value in Fahrenheit and c the value in Celsius: Conversion (temperature difference or interval)[ ]When a temperature interval between °F and °C is converted, the ratio is only used, without any constant (in this case, the interval has the same numerical value in Kelvin as in Celsius degrees): History[]Fahrenheit proposed its temperature scale in 1724, based on two temperature reference points. In its initial scale (which is not the final scale of Fahrenheit), the zero point was determined by placing the one in "a mixture of , water and salis Armoniaci [transl. ] or even marine salt". This combination forms one that automatically stabilizes your temperature: 0 °F was defined to be that stable temperature. A second point, 96 degrees, was approximately the temperature of the human body (sanguine hominis sani, the blood of a healthy person). A third point, 32 degrees, was marked as the temperature of ice and water "without the salts mentioned". According to a German story, Fahrenheit chose the lowest measured air temperature in his home town (Gdańsk), in winter 1708/09 as 0 °F, and only later he had the need to make this reproducible value using the brine. According to a letter that Fahrenheit wrote to his friend, his scale was built on the work of , whom he had known before. In , the brine freezes to zero, the water freezes and melts to 7.5 degrees, the body temperature is 22.5 and the water boils to 60 degrees. Fahrenheit multiplied each value for four to remove fractions and make the scale more. He then calibrated his scale again using the ice melting point and normal human body temperature (which were at 30 and 90 degrees); adjusted the scale so that the ice melting point was 32 degrees and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark grade lines in his instruments simply by bising the interval six times (since 64 is 2 to the sixth power). Fahrenheit soon afterwards observed that water boils about 212 degrees using this scale. The use of freezing points and boiling water as fixed reference points thermometer became popular after the work of and these fixed points were adopted by a committee of the lead in 1776. Under this system, the Fahrenheit scale is slightly redefined to make the water freezing point exactly 32 °F, and the boiling point is exactly 212 °F or 180 degrees higher. It is for this reason that it is approximately 98.6° (oral temperature) in the revised scale (as it was 90° in the Fahrenheit multiplication of Rømer, and 96° in its original scale). In the current Fahrenheit scale, 0 °F no longer corresponds to the eutectic temperature of the ammonium chloride breeze as described above. Instead, that eutectic is approximately 4°F in the Fahrenheit final scale. He was based on the temperature scale Fahrenheit, with its zero representing instead. Usage[]The Fahrenheit scale was the primary temperature standard for climate, industrial and medical purposes in English-speaking countries until the 1960s. In the late 1960s and 1970s, the Celsius scale replaced Fahrenheit in almost all those countries, with the notable exception of the United States and in some cases, the United Kingdom—normally during its overall process. Fahrenheit is used in the United States, its territories and associated states (all served by the United States) as well as for everyday applications. For example, weather forecasts in the United States, food cooking and freezing temperatures are usually given in Fahrenheit grades. Scientists, like meteorologists, use Celsius or kelvin degrees in all countries. At the beginning of the 20th century, and Dale suggested that the reasons for resistance to the use of the centigrade system (now Celsius) in the United States included the larger size of each Celsius grade and the lower zero point in the Fahrenheit system. Canada favoring , while also maintaining legal definitions for traditional Canadian imperial units. Canadian weather reports are transmitted using Celsius degrees with occasional reference to Fahrenheit especially for cross-border transmissions. Fahrenheit is still used in virtually all Canadian ovens. Thermometers, both digital and analogous, sold in Canada often use the Celsius and Fahrenheit scales. In the European Union, it is mandatory to use kelvins or Celsius degrees when the temperature is cited for "economic, public health, public safety and administrative purposes", although Fahrenheit grades can be used along with Celsius grades as a supplementary unit. For example, those used in the UK follow the recommendations of ISO 3758:2005 that show the water temperature of the washing machine in Celsius grades only. The equivalent label in North America uses one to six points to denote the temperature with an optional temperature in Celsius degrees. Fahrenheit is still commonly used in the UK in a common conversation, but less so with young people and many people use both depending on the context. Within unregulated sectors, such as journalism, the use of Fahrenheit in the UK does not follow any fixed pattern with Fahrenheit degrees often appearing along with Celsius degrees. does not mention Fahrenheit on your daily weather page, while also has an all-metric daily weather page but has a Celsius-to-Fahrenheit conversion chart. In publishing news, much of the British press has adopted a tendency to use Celsius degrees in headlines and discussions related to low temperatures and Fahrenheit for medium to high temperatures.[] In February 2006, the writer of an article in suggested that rationality was one of emphasis: "−6 °C" sounds colder than "21 °F" and "94 °F" sounds more impressive than "34 °C".
