Temperature is a physical quantity characterizing the thermodynamic state of the object. Currently, for measuring the temperature taken several ways.
In Russia and several other countries, including the European, the most common parameter used to measure temperature is degrees Celsius. It got its name by the name of the author of this temperature scale Celsius Alexander, who has put forward a proposal in 1742.
Initially, the idea of Celsius is based on the basic States of aggregation of water: thus, the temperature of freezing was taken as 0 degrees. Thus, temperature below 0, that is, those in which water is in solid condition, was related to negative temperatures. The boiling point of water was taken as 100 degrees: these reference points allows to calculate the band gap of 1 degree Celsius.
Subsequently was developed the Kelvin scale, absolute zero, the host, that is the minimum physically possible temperature, 0 degrees Kelvin (0 degrees Kelvin), scales of Kelvin and Celsius were aligned among themselves. Now, in order to set the temperature of the substance in degrees Celsius, you need to temperature on the Kelvin scale, add 273,15.
The German scientist Gabriel Fahrenheit developed his scale almost simultaneously with the C: in 1724. He, like Celsius, take into account the physical state of water, however, identified their other numbers. So, freezing point of water in Fahrenheit scale is 32 degrees, and boiling point is 212 degrees. Based on this temperature range was measured, the magnitude of one degree Fahrenheit, which is 1/180 of the difference between the freezing point and the boiling point of water in degrees.
To implement a translation of temperature values from Celsius to Fahrenheit and back, there are special formulas: Celsius temperature=(Fahrenheit temperature - 32)*5/9. For example, 120 degrees Fahrenheit in accordance with this formula will be equal to 48.9 degrees Celsius.
For a reverse translation can use the following formula: temperature Fahrenheit=temperature Celsius*9/5+32. For example, 20 degrees Celsius using this formula will correspond to 68 degrees Fahrenheit. Both of these formulas can be used for conversion to the Fahrenheit temperatures Celsius.

Ratio of temperature Celsius and Fahrenheit
To implement a translation of temperature values from Celsius to Fahrenheit and back, there are special formulas: Celsius temperature=(Fahrenheit temperature - 32)*5/9. For example, 120 degrees Fahrenheit in accordance with this formula will be equal to 48.9 degrees Celsius.
