Convert Fahrenheit to Celsius

Delight provide values below to convert Fahrenheit [°F] to Celsius [°C], or vice versa.

Fahrenheit

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

History/Origin: The Fahrenheit scale was developed based on a measurement proposed in 1724 by the German language physicist Daniel Gabriel Fahrenheit. He initially based the calibration on an equal water ice-salt mixture, selecting the values of 30°F for the freezing point of water, and 90°F for normal body temperature. He later adjusted the calibration such that the melting point of water ice was 32°F and body temperature was 96°F. He chose these values to simplify the degree markings he could make on his instruments, since this divergence between the temperatures allowed him to marking caste lines past bisecting the interval half dozen times. After, when using the freezing and humid points of h2o 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 indicate, resulting in normal human torso temperature being approximately 98°F, rather than Fahrenheit'due south 96°F.

Current use: Until the 1960's the Fahrenheit scale was the principal scale used in English-speaking countries. Today, most countries around the world use the Celsius temperature scale instead, many having made the change during their metrication processes (conversion to using the metric system of units). Notwithstanding, the Fahrenheit scale is withal used as the official temperature calibration in a number of countries, including the U.s. (as well every bit 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 defined based on the SI unit of temperature, the kelvin. The Celsius and Kelvin scales are precisely related, with a ane-degree alter in Celsius beingness equal to a 1 degree-change in kelvin. The kelvin (and thus Celsius) is divers based on the Boltzmann abiding, chiliad, which equals 1.380649 × 10^-23 when expressed in the unit J·K^-1, a unit of measurement equivalent to kg·mⁱⁱ·s^-2·K^-1. The kilogram, meter, and second, are defined based on Planck's constant, h, the speed of light, c, and cesium frequency, ΔνCs.

History/origin: From 1743 until 1954, the Celsius scale was based on 0°C for the freezing betoken of water and 100 °C for the boiling point of water, both at a pressure of ane standard atmosphere, using mercury as the working material. This was non ever the case, and originally 0°C was defined as the humid point of water and 100°C was defined as the melting point of snow. Celsius as a unit and a calibration was not widely used until this original definition was inverted. In 1954, the unit, "degree Celsius," too as the Celsius scale were again re-defined to instead be based on absolute zero (-273.fifteen °C) and the triple bespeak of VSMOW (specially purified water). This is the definition that was used upwards until 2019, when the kelvin was redefined based on the definitions of the second, meter, and kilogram.

Current use: The Celsius scale replaced the Fahrenheit scale in nearly countries in the mid to late 20^thursday century. Almost all countries around the world use this scale, except for those in which the metric arrangement has not been adopted, such equally the United States. Even in countries like the United States however, Celsius is widely used inside the scientific community—information technology just is not widely used in everyday temperature references.
