get State name from region_id Magento 1.6.2

Question

I need to display a single State Name in Magento 1.6.2 by converting the region_id to the state name.

I have the region_id and can return the array of all US states with

$states = Mage::getModel('directory/country')->load('US')->getRegions();

but cannot find a help class that converts the region_id.

Answer 1

$regionId = 27;
$region = Mage::getModel('directory/region')->load($regionId);
echo $region->getName();
