A simple loop through the array:
// the magic: define what group has what
// index in the first array
$option_index = array(
'weight' => 0,
'height' => 1,
'width' => 1
...
);
foreach($units as $i => $unit ) {
// pull the group name out
$group = $unit['caption_name'];
// what index this group is assigned
$index = $option_index[$group];
// create a new second level array
// with the proper data.
$options[$index][] = array(
'unit_id' => $unit['unit_id'],
'unit_option' => $unit['unit_option'] );
