Temperature Converter (Celsius, Fahrenheit, Kelvin) by

Our temperature conversion calculator provide 4 units conversion and we are working on improving the tool to add more unit below. Below are temperature units you should know; we already handle the first four in our tool:

  • Celsius
  • Fahrenheit
  • Kelvin
  • Rankine
  • Delisle
  • Newton
  • Réaumur
  • Rømer

This tool is simple to use; let's say that you want to change the first text box from ºF to Kelvin (K) or Kelvin (K) to ºC, all you need to do is:

  1. Using the drop-down menu, click on ºC to change units from Fahrenheit to Kelvin by selecting Fahrenheit (ºF).
  2. On the second text box, select Kelvin (K). You now have changed the units from Fahrenheit to Kelvin on the second field.
  3. Once you set the desired temperature unit you want the outcome to be, go ahead and enter the value in the box above, and watch as the tool perform the magic - you will see the tool display result in the unit you want automatically.

Now you don't need to know all the temperature conversion formula.

What is Temperature?

Temperature is a measure of the average kinetic energy of the particles in an object. When the temperature increases, the motion of these particles also increases. Temperature is measured with a thermometer or a calorimeter.

Thermodynamic temperature

According to 13de CGPM (1967), Rés. 4, the Kelvin, a unit of thermodynamic temperature, is equal to 1/273.16 of the triple point of water's thermodynamic temperature.

To better understand temperature without complicated scientific terminologies, Temperature, simply put is the degree of hotness or coldness of an object.

The decision to use the Kelvin rather than "degrees Kelvin" as the unit of temperature was made during the 13th CGPM in 1967. Water's triple point is 273.16 K, or 0.01 oC. (degrees Celsius).

The triple point of water is specified as 0.01 oC.
In the ideal gas scale, a change of one degree in temperature is equal to one degree Celsius.
The convergence of three phases of a substance, like water, is known as the triple point in theory. This means that a matter's liquid, solid, and gas phases all manifest simultaneously. This is virtually unattainable.

The concept of monitoring temperature has been around for a very long time. Galen was one of the first people to attempt to create a temperature scale. He had a scale with four degrees for warmth and four for cold. Thermoscopes were the name given to the earliest temperature monitoring devices. Galileo replaced the air in the thermoscopes in 1610 with wine. Gabriel Fahrenheit invented the thermoscopes' medium mercury in 1724. Mercury was chosen because of its wide, largely homogenous thermal expansion and non-sticky surface on glass. Mercury similarly maintains its liquid state over a wide temperature range.

Temperature Scale

The two fundamental points on the current temperature scale are when water begins to freeze and when it begins to boil. A scale is created between these two temperatures. The Celsius scale, created by Anders Celsius, and the Fahrenheit scale, created by Gabriel Fahrenheit, are the two most widely used scales. The melting point of water is 32 degrees Fahrenheit, and the boiling point is 212 degrees Fahrenheit, according to the definition of the Fahrenheit scale. This indicates that there are 180 divisions between the freezing point and boiling point. In 1724, Fahrenheit unveiled his scale.

Fahrenheit Scale vs Celsius scale.

The Celsius scale is an additional scale. The freezing point of water is 0 degrees (centigrade) and the boiling point is 100 degrees on the Celsius scale (centigrade). This scale, also known as centiscale, has 100 divisions. The degrees Celsius scale took the place of the centigrade scale in 1948. The following two points establish the Celsius scale:

At 0.01 oC, water has its triple point.
In the ideal gas scale, a change of one degree in temperature is equal to one degree Celsius.
Water has a boiling point of 99.975 degrees Celsius at a pressure of 1 atmosphere. However, that was 100 on the centiscale.

SI temperature scale:

Temperature and molecular kinetic energy are linked concepts. When the temperature varies, the kinetic energy also does. The transmission of heat between two objects is known as temperature. The Kelvin scale is the basic unit of measurement for temperature. The Kelvin scale of temperature is dependent on the location of absolute zero. The molecules are no longer moving at this point, hence they are unable to produce heat. All molecules fall under this. The temperature at absolute zero, or 0 K, is -273.15 oC. The scale is identical to the Celsius scale.

The most common temperature scale in use today is the Celsius scale. Many nations, most notably the United States, continue to utilise the Fahrenheit scale. This tool is for you if you need a quick way to convert between these two temperature units. The SI unit for temperature, the Kelvin scale, can also be converted using this calculator.

In the United States, meteorologists measure the surface temperature in Fahrenheit and record their findings. The majority of other nations in the globe use Celsius. Understanding how to convert between degrees Fahrenheit and degrees Celsius is crucial. Since it starts at absolute zero, Kelvin is another temperature unit that comes in very helpful for many scientific computations (equal to -273.15 0C). As a result, the Kelvin scale does not have a negative number.
