Two important reference points for temperature are the boiling point and the freezing point of water. water freezes at 0degreesC or 32degreesF. Water boils at 100degreesC or 212degreesF.
\n" ); document.write( "--------
\n" ); document.write( "You have two points relating Fahrenheit to Celcius (F,C)
\n" ); document.write( "(32,0) and (212,100)
\n" ); document.write( "slope = 100/(212-32) = 100/180 = 5/9
\n" ); document.write( "Then 0=(5/9)32+b
\n" ); document.write( "b= -160/9
\n" ); document.write( "Celcius = (5/9)(Fahrenheit)-160/9
\n" ); document.write( "or
\n" ); document.write( "Farenheit = (9/5)(Celcius) +32
\n" ); document.write( "--------
