A quick fix for weight displyed as 0 if total weight is less than 1 (lbs/kg). This is because of rounding thats being done without any decimal digit.

In modules->shipping->upsxml.php

Find
$upsQuote = $this->_upsGetQuote();

2 lines below there are 2 statements starting with

$this->quotes = array('id' => $this->code,

within these lines is code snippet

round($totalWeight,0)

Change the 0 to number of decimal digits to round to

round($totalWeight,2)

This will display weight rounded to 2 decimal places like 0.20 etc.
