Sp here's the error:
exit status 1
no match for 'operator/' (operand types are 'SFE_BMP180' and 'double')

And:
char status;
double T,P,p0,a;
float height =(pressure/133.3-745.00)10.5;
Serial.println();
Serial.print("provided altitude: ");
Serial.print(ALTITUDE,0);
Serial.print(" meters, ");
Serial.print(ALTITUDE3.28084,0);
Serial.println(" feet");
status = pressure.startTemperature();
if (status != 0)
{
delay(status);
Please help ^^

ruslakoff:
no match for 'operator/' (operand types are 'SFE_BMP180' and 'double')

Where is "pressure" defined? The compiler is seeing "pressure" as being type "SFE_BMP180", whatever that is. Basically it doesn't know how to do division with whatever "pressure" is.

i have same problem with ruslakof.
no match for 'operator/' (operand types are 'MAX6675' and 'double')
if I can't divide a sensor by a number. so what i should do to get another variable from sensor?

You need to get a value from the sensor, probably using something like xxxx.readCelcius(), depending on what library you're using and what you've called the sensor.

In other words, how can we tell you how to change your code without first seeing the blasted code? Post your code (in </> code tags please)! And the complete error (also in </> code tags).

if I can't divide a sensor by a number.

What on earth are you trying to do? Hold up the sensor. Why on earth would you want to divide that by a number?
