Fahrenheit Centigrade Math
The notation c represents the temperature in celsius and f is the temperature in fahrenheit.
Fahrenheit centigrade math. For a 100 accurate answer subtract 32 and divide by 1 8 or use the calculator above fahrenheit to celsius table. For fahrenheit the points were way more arbitrary. Celsius c fahrenheit 32 1 8 if required there are worked examples below which use this formula to show how to convert a temperature in fahrenheit to a temperature in celsius. To go from fahrenheit to celsius take 30 off the fahrenheit value and then half that number.
C 5 9 x f 32. The slope of each system determines the convergence at 40 degrees and nothing more. Subtract 32 from the fahrenheit temperature. After you know the formula it is easy to convert fahrenheit to celsius with these three steps.
If you know the temperature in fahrenheit and want to convert it to celsius first subtract 32 from the temperature in fahrenheit and multiply the result by five ninth. T c t f 32 5 9. For celsius those points are the temperatures when fresh water freezes 0 c and boils 100 c. That is the freezing point of sea water 0 degees and body temp which was thought to be 100 degrees at that time.
