US Unit System in iRohr 1.1.2!

Just submitted a new version of iRohr ( 1.1.2) to the App Store.
The new release includes a option between the Metric and the US Unit System.
It probably will be ready for update next week.

If there are any unit you might miss or pipe materials that should be included in the next update just send me a mail to 'irohrapp@gmail.com'.
