## Celsius conversion to forenhiet ?

### Celsius Conversion  forenhiet:

Celsius conversion forenhiet is listed below. Celsius and Fahrenheit are thermodynamic temperature scales used to calculate the temperature of a body, object or element. Designated in degrees, they have different units of measurement and are used one or the other, and sometimes one in addition to the other, depending on the country. Created in 1724 by the physicist of the same name, the Fahrenheit scale has since given way to the Celsius scale in many countries (although some as the United States have retained it, or as Canada use both measures with a preference all the same for the Celsius). Let’s see together how to proceed with the conversion Celsius – Fahrenheit, and learn more about the reasons for their respective uses.

## Celsius conversion – Fahrenheit

To proceed to the Celsius – Fahrenheit conversion, one can not rely on a simple multiple. A relatively complex calculation is required where the objective is to subtract the number 32 from the first data and divide the result by 1.8 (which corresponds to the fraction 9/5). Starting from this principle, we can deduce two applicable equations which go in one direction as in the other (knowing that T (C °) is the temperature in degrees Celsius, and T (F °) is the temperature in degrees F).

So, to convert to degrees Celsius a temperature in degrees Fahrenheit, we put this equation:

• T (C °) = (T (F °) – 32) / 1.8

For the example, let’s imagine that we have a temperature indication of 50 ° F, which we want to convert to ° C:

• T (C °) = (50 – 32) / 1.8
• T (C °) = 18 / 1.8
• T (C °) = 10

It can therefore be said that 50 ° F is equivalent to 10 ° C.

## The conversion Fahrenheit – Celsius

Conversely, in order to proceed with the Fahrenheit – Celsius conversion, we will have to multiply the given figure in ° C by 1.8 and add to it the fixed figure of 32. This gives us now this equation:

• T (F °) = (T (C °) x 1.8) + 32

Let’s take an example with a temperature of 25 ° C. The calculation is as follows:

• T (F °) = (25 x 1.8) + 32
• T (F °) = 45 + 32
• T (F °) = 77

That is, 25 ° C are equal to 77 ° F.

## Why the number 32?

If the figure 32 returns quite exactly in the calculation whatever the basic data, it is that it corresponds to the melting temperature of the ice. By melting ice, means when the ice is created, that the gel takes shape. Indeed, in the temperature scale, this melting level of the ice is measured at 0 ° C (as we already know) and corresponds to 32 ° F.

## Comparison on some remarkable temperatures

Let’s take a look at some points of comparison between Celsius and Fahrenheit on temperatures of remarkable character:

• melting point of the ice: 0 ° C and 32 ° F
• approximate human body temperature: between 37 ° C and 38 ° C, and between 98.6 ° F and 100 ° F

boiling point of water at normal atmospheric pressure: 100 ° C and 212 °
