Answer 1

In this case you can use magento event/observer.There are lot of events are exiting in by whose you can set general_weight basic of weight.

As you have using this code.There some issue in your observer.

Don't need to load the product object Again

  <?php
class Moh3n_Attvaluecopier_Model_Observer
{
    public function copyAttribute($observer)
    {
        $finalTemWeight=$observer->getEvent()->getProduct()->getData('weight');
        $observer->getEvent()->getProduct()->setData('general_weight',$finalTemWeight.'KG');
        return $this;
    }
}

Answer 2

observer.php should be like this:

<?php

class Moh3n_Attvaluecopier_Model_Observer
{

public function  copyAttribute($observer){

    if(!$this->_processFlag):

        $this->_processFlag=true;
        $_product = $observer->getProduct();
        $_productid = $_product->getId();
        $productModel = Mage::getModel('catalog/product');
        $loadCurrentProduct = $productModel->load($_productid);
        $loadCurrentProduct->setGeneralWeight(intval($loadCurrentProduct->getWeight()));
        $weight = intval($loadCurrentProduct->getWeight());
        $gw = (string)$weight. " KG";
        $loadCurrentProduct->setGeneralWeight($gw);
        $loadCurrentProduct->save();
        endif;}
    }
