Temperature Unit Converter

The Temperature Unit Converter allows you to convert between eight different units. Enter the temperature you wish to convert into the appropriate box below. The results for the other temperature units appear in the other fields. You can convert between the following units Celsius (°C), Fahrenheit (°F), Kelvin (°K), Rankine (°R), Newton (°N), Réaumur (°Ré), Delisle (°De), Rømer (°Rø).

Thermodynamic Temperature - Definition

The fundamental SI unit of temperature is the kelwin. Its symbol is K and it is defined by taking the fixed numerical value of Boltzmann's constant k, which is 1,380,649 × 10⁻23, expressed in the unit J K⁻1, which is equal to kg m2 s⁻2 K⁻1, where kilogram, metre and second are defined by h, c and ΔνCs.

Who might find the temperature unit converter useful?

Converter of temperature units can be useful for many people and in many situations. Here are some examples of groups of people who may benefit from such a converter:

  1. Travellers: People travelling to places with different temperature scales can use a temperature unit converter to convert temperatures from one system to another. For example, if you are travelling from a country where the Celsius scale is used to a country where the Fahrenheit scale is used, the converter will allow you to convert temperatures, making it easier to understand local weather conditions.
  2. Scientists and engineers: A temperature unit converter is essential for those working in scientific fields such as physics, chemistry, meteorology or engineering. Many experiments and calculations require the conversion of temperatures between different scales such as Celsius, Fahrenheit or Kelvin.
  3. Cooks and bakers: Temperature is important in the kitchen, especially when making cakes, desserts or bread. A temperature unit converter can help cooks and bakers convert oven temperatures from one scale to another, such as Celsius to Fahrenheit.
  4. Medical professionals: In medicine, different temperature scales are often used, both to measure a patient's body and to store samples or medicines. A temperature unit converter can be useful for medical professionals to convert temperatures between different scales, such as Celsius, Fahrenheit or Kelvin.
  5. Investors and traders: Some financial markets, such as commodity markets, often use different temperature units, such as for oil futures. Investors and traders can use a temperature unit converter to track price and value changes in these markets.

These are just a few examples, and a temperature unit converter can be useful in many other areas where temperatures need to be converted between different scales.

Thermometric scales

To determine the temperature scale, fixed thermometric points are required which correspond to reproducible states of interfacial equilibrium, e.g. in the Celsius scale, the freezing and boiling points of distilled water at a pressure of 1 atm. The scale is divided into a certain number of degrees.

In the Temperature Unit Converter you will find the following scales:

Celsius scale - the most popular scale for measuring temperature. Its name comes from the Swedish scientist Anders Celsius, who introduced it in 1742. Today, the reference points are the freezing point of water (0°) and the boiling point of water at atmospheric pressure (100°). Originally these two points were taken in reverse order,

Fahrenheit scale - used in the USA, the Cayman Islands, the Bahamas and Belize, and as a supplementary scale in Canada. It takes its name from its creator, Daniel Gabriel Fahrenheit, who proposed it in 1742. Fahrenheit originally used three reference points for his scale: 0° as the freezing point of a 1:1:1 mixture of water, ice and salmiak, 32° as the temperature of ice and water in a 1:1 ratio, and 96° as the temperature of the human body. A few years before his death, he made a modification, setting the boiling point of water at 212°, as more important to science than the human body temperature. Since then, the human body temperature has been set at 98.6°F. It is also worth mentioning that Fahrenheit modelled the Rømer scale,

Kelvin scale - is the base unit of temperature in the SI International System of Units. It is named after the Scottish physicist William Thomson, Lord Kelvin, and is denoted by the letter K. The Kelvin scale is based on the Celsius scale. The difference between one scale and the other is 273.15. The temperature of 0 K corresponds to -273.15 °C and is theoretically the lowest possible temperature (absolute zero).

Rankine scale - its creator is William Rankine. 0 on this scale represents the lowest possible temperature that a perfect crystal can have, where all molecular vibrations have ceased (absolute zero). There is a relationship between values on the Rankine scale and values on the Fahrenheit scale:
TRank = TFahrenheit + 459,67

Newtonian scale - developed in 1700 by the British scientist Isaac Newton. Initially it was based on a number of temperatures he defined corresponding to certain phenomena. Later it was modified and its definition included the melting and boiling points of water, to which values were assigned: 0° and 33°N.

Réaumur scale - developed and introduced in 1731 by the French physicist R.A.F. de Réaumur. 0° Ré is the freezing point of water and 80° Ré is the boiling point of water. There is a relationship between values on the Réaumur scale and values on the Celsius scale:
TRéaumur = TCelsjusz + 0,8

Delisle scale - developed and introduced in 1732 by the French astronomer Joseph-Nicolas Delisle. It was used mainly in Russia until the 18th century. To develop the scale, two points were adopted: 0°D - boiling water, 150°D - freezing water.

Rømer scale - developed and introduced in 1701 by the Danish astronomer Ole Rømer. 0° on the Rømer scale is the freezing point of a mixture of water and salt. The boiling point of water is 60 °Rø and its freezing point is 7.5 °Rø.

0°C != 0°F != 0°K

For some temperature units, a value of 0 means a completely different value. This is due to the way the scale was created. For the Celsius, Réaumur and Newtonian scales, it was assumed that 0 means the freezing point of water.

For the Kelvin and Rankine scales, 0 means the lowest theoretically possible temperature a body can have. This temperature cannot be reached. According to physics, it is the temperature at which all vibrations of particles cease. Such a temperature is also called absolute zero.
