Today measurement of Fahrenheit temperature is widely used in only two countries of the world, and in all others prefer Celsius scale. However owing to the fact that one of these two countries - the USA, the question of transfer of degrees Fahrenheit to degrees Celsius rises not so seldom. Besides at literature of the English-speaking countries forty-year-old (and more) prescription there are mentions of Fahrenheit temperature too.
Instruction
1. Take away from temperature taken in degrees by the Fahrenheit scale, number 32, increase the received result by number 5, and then divide it into number 9. The received value will also show temperature in degrees on Celsius scale corresponding to a reference value in degrees Fahrenheit. For example, temperature of 451 °F corresponds (451-32)*5/9 ≈ 232.78 °C. And it means that there is Ray Bradbury not the American, his well-known fantastic novel anti-Utopia would be called not Fahrenheit 451, but Celsius 233.
2. At the return transformation of degrees Celsius to degrees Fahrenheit it is important not to get confused - at first increase the number of degrees by the nine and divide into the five, and then increase the received result by 32 degrees. For example, recalculation of 100 °C in units of the Fahrenheit scale has to give 100*9/5+32 = 212 °F. Such is temperature at which water turns into gaseous state (couples) if to express it in degrees Fahrenheit.
3. Use the posted online scripts of automatic transformation of degrees Fahrenheit to degrees Celsius and back is a way which demands least of all efforts. For example, pass to the http://convertr.ru/temperature/fahrenheit_degrees page and enter Fahrenheit temperature. Nothing requires to press sending for the server here as all calculations happen directly in your browser, and the result is displayed at once. Except an equivalent of temperature entered by you in degrees Celsius, on the same page will be displayed also value in kelvins (temperature unit of measure in the SI system) and in degrees by the Reaumur scale (still it is sometimes used in France).
4. Use the calculator which is built in the operating system of your computer if there is no Internet access. In Windows OS it can be started, for example, at the same time having pressed the keys win + r, then having entered the calc team and having clicked the OK button. For recalculation by means of this application use the algorithm described in the first and second steps.
