Imperial Weights After Fedex Update

-- HikaShop version -- : 2.6.1
-- Joomla version -- : 3.6.5

Hi,
I just upgraded the Fedex plugin to correct some issues. After doing so and everything looked OK. Fedex informed me that the site is now sending all weights in Pounds/Ounces/Inches etc.

I looked at fedex.php and can see this is hard coded throughout the file eg:
if($pkg == "LBS")
or
($order, array('weight_unit' => 'lb', 'volume_unit' => 'in',

And so on.
I intend to change this to metric but want to make sure it won't effect anything else. All of my measurments are in metric - g/mm etc.
I have everything in the backend (products etc.) set to Grams and Millimeters so should I use g & mm or KG & CM???

Thanks.

Hello,

Yes, the FedEx plugin is now sending products weight and dimension in LB and IN.

I intend to change this to metric but want to make sure it won't effect anything else. All of my measurments are in metric - g/mm etc.
I have everything in the backend (products etc.) set to Grams and Millimeters so should I use g & mm or KG & CM???

$limit = array(
	'y' => 119,
	'w' => 150,
	'length_girth' => 165
);
if(!empty($rate->shipping_params->methods)) {
	foreach($rate->shipping_params->methods as $k => $service_name) {
		$l_lenght = 0; $l_weight = 0; $l_dimension = 0;
		if($service_name == 'FEDEX_GROUND')
			$limit['y'] = 108;
		if($service_name == 'GROUND_HOME_DELIVERY')
			$limit['w'] = 70;
		if(in_array($service_name,$international_limit))
			$limit['length_girth'] = 130;
	}
}

Thanks for the advice
