===== Temperature conversions =====

Fahrenheit to Celsius

C = (F - 32.0) / 1.8\\

Celsius to Fahrenheit\\

F = (C * 1.8) + 32.0\\

==== C source ====

float C_to_F_degrees( float temp )\\
{\\
return( (temp * 1.8) + 32.0 );\\
}\\

float F_to_C_degrees( float temp )\\
{\\
return( (temp - 32.0) / 1.8 );\\
}\\


==== Converting C to F for One Wire ====

unsigned int temperature;\\
float tempf;\\
tempf = 32.0 + (9.0*(float)temperature)/10.0;\\
temperature = tempf + 0.5;                         // integer Fahrenheit\\
