Manually change types

To change the type of a measurement without altering its value use setType().

Example 621. Changing the type

<?php
$unit 
= new Zend_Measure_Length(1,Zend_Measure_Length::METER);
echo 
$unit// outputs "1 m"

$unit->setType(Zend_Measure_Length::KILOMETER);
echo 
$unit// outputs "1000 km"
