    >># include <iostream.h>

    Neither of these are legal C++ anymore. They may work on modern compilers and will work on older compilers, but keep in mind that you are working with pre-standard C++.

    >>double on,lb,gramo,kilo,gina,total;
    There is no reason to use global variables when the only function in your program is main.

    >>void main()
    This has never been correct. main returns an integer.

    Here is the same code modernized, corrected, and with consistent formatting.
    Code:
    #include <cstdlib>
    #include <iostream>
    
    using namespace std;
    
    int main() 
    {
      double on, lb, gramo, kilo, gina, total;
      char no;
    
      do{
        cout << " \n Put Ur Weight In thE sYsteM EnglIsH ";
        cout << "\n "; 
        cout << "\n libras: ";
        cin >> lb;
        cout << " onzas: ";
        cin >> on;
    
        kilo = lb / 2.2046;
        gramo = on / .0352736;
        gina = gramo / 1000;
        total = kilo + gina;
    
        cout << "\ntu el peso en kilos es " << kilo;
        cout << "\nY en gramos es " << gramo;
        cout << "\n\n Pero en Total Tu peso es " << total;
        cout << " \n\n deseea otra operacion??s/n "; 
        cin >> no;
        cout << "\n";
      }while (no != 'n');
    
      return 0;
    }

    no offense, but i'm kindof surprised your teacher is teaching you global variables this early on. there is always a way around using them, except for very very rare cases. i've seen teachers teach void main, as though it should, i see some of their points in doing so in the beginning..

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
