Is the unit of thermometer only Celsius

It's not Fahrenheit in the United States.

It is converted to f=9c 5+32 degrees Celsius

There is also the international temperature scale K

The conversion relationship with Celsius is k=c-273

273 is said to be an absolute 0 degrees.

The temperature can only get infinitely close to this number, but it can never be reached.

Temperature: Temperature is a physical quantity that characterizes the degree of heat and cold of an object, and microscopically it is the intensity of the thermal movement of the molecules of an object. Temperature can only be measured indirectly by certain characteristics of an object as a function of temperature, and the scale used to measure the temperature value of an object is called a temperature scale.

It specifies the starting point (zero point) of the temperature reading and the basic unit for measuring the temperature. There is no high pole of temperature, only the theoretical low pole "absolute zero". "Absolute zero" cannot be achieved in a limited number of steps.

At present, the most widely used temperature scales in the world are Fahrenheit temperature scale, Celsius temperature scale (°C), thermodynamic temperature scale and international practical temperature scale.

Temperature is a manifestation of the average intermolecular kinetic energy within an object. The faster the molecule moves, the hotter the object, i.e., the higher the temperature; The slower the molecular motion, the colder the object, i.e., the lower the temperature. This phenomenon is described as the thermal potential, or energy effect of an object.

When the temperature is expressed as a numerical value, it is called a temperature degree. It is worth noting that a small number of molecules or even a system of molecular composition have no temperature significance due to the lack of statistical quantitative requirements.

The temperature of the gas in the atmosphere is air temperature, which is a common term used in meteorology. It is directly affected by sunlight: the more sunlight, the higher the temperature.

Celsius and Fahrenheit].

Fahrenheit and centigrade are both units used to measure temperature. Many countries in the world, including China, use Celsius, and the United States and some other English-speaking countries use Fahrenheit and less so Celsius.

Fahrenheit is named after its inventor, Gabriel DNamed by Fahrenheir (1681-1736), its freezing point is 31°F and its boiling point is 212°F. In 1714, the German Fahrenheit used mercury as the temperature measurement medium to make a glass mercury thermometer, selected the temperature of the mixture of ammonium chloride and ice water as the zero degree of the thermometer, and the human body temperature was 100 degrees of the thermometer, and divided the mercury thermometer from 0 degrees to l00 degrees according to the volume expansion distance of mercury into 100 parts, each of which was 1 degree Fahrenheit, and was recorded as "1".

According to the Fahrenheit scale, the ice temperature scale of the water is in Celsius.

The inventor of the Celsius was Anders Celsius (1701-1744), which had a freezing point of 0 ° C and a boiling point of 100 ° C. In 1740, the Swede Celsius proposed that the freezing point of water be set at 0 degrees and the boiling point of water at 100 degrees at standard atmospheric pressure. The glass mercury thermometer is indexed according to the two fixed temperature points of water.

100 aliquots are made between two points, and each portion is called 1 degree Celsius. Write as 1.

Relationship between Celsius and Fahrenheit: t = +32

The commonly used unit of temperature is Celsius, which is denoted by the symbol " ".

Generally, people use thermometers to measure temperatures, and thermometers generally include mercury thermometers, thermometers, electronic thermometers, etc.

The SI unit of temperature is Kelvin and is denoted by the symbol "k".

The Kelvin temperature scale is established with an ideal gas, and its zero point is called absolute zero. According to the kinetic theory, when the temperature is at absolute zero, the kinetic energy of the gas molecules is zero. For convenience.

The scale unit of the Kelvin thermometer is the same as the scale unit on the Celsius thermometer, that is, one degree on the Kelvin thermometer is equal to one degree on the Celsius thermometer, 0 on the freezing point Celsius thermometer for water, and 0 for the Kelvin thermometer.

There are 6 units of measurement for temperatureKelvinunits, Fahrenheit, and temperaturesCelsius temperature scale, Lienard degrees, Ranlit degrees, Newtonian temperature scales.

Fahrenheit:

Fahrenheit and Celsius are both units used to measure temperature. Many countries around the world, including China, use Celsius, and the United States and some other English-speaking countries use Fahrenheit and less so Celsius.

Fahrenheit (°F): A unit of measurement for temperature. Fahrenheit:

F=32+ degrees Fahrenheit is named after its inventor, the German Gabriel DNamed after Fahrenheit (Wallenheit 1681-1736), its freezing point is 32°F.

The boiling point is 212°F. He discovered that liquid metal mercury was more suitable for making thermometers than alcohol, and he invented the mercury thermometer. When atmospheric pressure.

Finally, set the freezing point of water to 32 degrees and the boiling point of water to 212 degrees, and divide the temperature between 32 degrees and 212 degrees into 180 equal parts, each equal divided into 1 degree Fahrenheit.

Celsius; In physics, Celsius temperature is expressed as t, and absolute temperature (in Kelvin) is expressed as t;

Attached: Fahrenheit °F

Fahrenheit = 32 + Celsius

Celsius = Fahrenheit - 32).

The four temperature units - Celsius, Fahrenheit, Absolute, Lieseith Celsius, the temperature at freezing point is 0 degrees Celsius, the boiling point is 100 degrees Celsius and Fahrenheit sets the freezing point temperature at 32 degrees Fahrenheit and the boiling point is 212 degrees Fahrenheit, so 1 degree Celsius is equal to Fahrenheit Celsius The conversion formula between Celsius and Fahrenheit is: 5 (f- 50 ) = 9 (c-10) where f - Fahrenheit, c - Celsius absolute temperature is expressed by k = (t is Celsius) When the absolute temperature is 0, All motion, including the motion of the molecules, stops, and the internal energy of the matter is zero. The Liechter temperature, also known as the Liechter temperature scale, with the symbol R°, specifies that the freezing point and the boiling point of water (at standard atmospheric pressure) are divided into 80 units (ice-water mixture t=0°r, boiling point t=80°r).

It is currently used in Germany. The conversion relationship between Lienar and Celsius is as follows: 1°r = = where °r is Lienar and Celsius.

"At standard atmospheric pressure, the freezing point of water is 0 degrees, the boiling point of water is 100 degrees, and the temperature scale is divided into 100 equal parts. ”

Therefore, it is generally believed that the boiling point of water is 100 at 1 standard atmosphere, but this is no longer the case after 1990 (the boiling point of water used in 2013 is 1 standard atmosphere.

The 1990 International Temperature Scale (ITS-90) unifies the Celsius temperature scale and the thermodynamic temperature scale, stipulating that the Celsius temperature scale is derived from the thermodynamic temperature scale, 0 =, and the division remains unchanged. Therefore, the freezing point is not strictly equal to 0 (1 10000 is different), and the boiling point of water is not strictly equal to 100 (10000 to make a difference).

The Celsius temperature scale we commonly use now starts from the temperature of the ice-water mixture of pure water at a standard atmospheric pressure and ends at the temperature of the water boiling, and is divided into 100 parts, and the temperature of one serving is called 1 degree Celsius. There is also the common Fahrenheit degree in the United States, which starts from the temperature of the ice-water mixture of ammonium chloride saturated solution and ends at the normal body temperature of the human body, which is divided into 100 parts, and the temperature of one part is called 1 degree Fahrenheit.
