current DHT22 library uses only metric system (Celsius). convert this temperature in Fahrenheit and send this value to server. Also change unit of measure °C - > °F.

Here is function:
double Celcius2Fahrenheit(double celsius)
{
return celsius * 9 / 5 + 32;
}

per example if you have :

value_degrees_C = getDHTtemperature();

just add a line after :

value_degrees_F = (value_degrees_C*9/5)+32
