it does NOT have metric values

The ruler may be correct but it is very bothersome to start yet another app to translate from feet and inches just to get the right values.
I bought this today and if an update comes with metric values I will give it full score but now it is useless for me ;-(
But still I like the idea so I give it a 2 and if it comes with metric Ill give it a 4 or 5 star
