Examples of Temperature conversion

Temperature measurement units represent the physical magnitude of the heat level of a body or environment. Temperature is a property associated with the movement of particles within bodies and air, and it determines different properties of bodies, probably the most notable of which is their state. This is commonly seen in water, where temperature determines whether the same body (water) will be in a solid, liquid, or gaseous state .

The same thing happens with all substances , and for each one it is possible to determine the temperature at which it will be solid at the bottom and liquid at the top ( melting point ) and the temperature at which it will be liquid at the bottom and gaseous at the top ( evaporation point ). For the above reasons, the physical property of temperature is fundamental to the treatment of bodies and matter, and with it, it is essential to be able to quantify it. Throughout history, different ways of measuring temperature have appeared , functional for different cases. The three most important ones will be detailed, in chronological order of their appearance:

• The Fahrenheit degree. It was proposed in 1724 and was determined under three points so that its measurement does not follow a dynamic of direct proportionality. Its use is widespread in the United States, for non-scientific purposes.
• The degree Celsius. It was introduced in 1742, and its magnitude was determined based on the freezing and boiling points of water, with 0 Celsius being the point at which water turns from solid (ice) to liquid (or vice versa), and 100 Celsius being the level at which, once surpassed, water boils and turns into steam. This scale is used for most everyday temperatures in most parts of the world, but it is also commonly found in various types of scientific studies.
• The Kelvin degree. It was introduced in the mid-19th century and is known as an absolute temperature level because it places its zero point at the lowest energy level, that is, the point at which particles cease to move. In this sense, there is no such thing as 0 Kelvin, and at such a potential point, all substances would become solid. It is commonly used in scientific research but practically nonexistent in everyday use. It is not symbolized by the degree sign (°) because it is not a gradual magnitude but an absolute one.

In this context, the three different temperatures must have clear mechanisms for conversion. Here are the six possible transformations between temperature units, and how to do them correctly.

• From Celsius to Kelvin: KELVIN = CELSIUS + 273.15
• From Celsius to Fahrenheit: FARENHEIT = (CELSIUS) *9/5 + 32
• From Fahrenheit to Celsius: CELSIUS = (FARENHEIT – 32) * (5/9)
• From Fahrenheit to Kelvin: KELVIN = (FARENHEIT – 32) * (5/9) + 273.15
• From Kelvin to Celsius: CELSIUS = KELVIN – 273.15
• From Kelvin to Fahrenheit: FARENHEIT = ((KELVIN – 273.15) * 9/5 ) + 32
