Don't worry, Paul. Would just have been a wish since the metric weight is what I mostly use and run in my head, so to speak. But converting isn't a problem at all. I just thought that it might be just some parameter change in the xml code. You know, go to this line, change the ratio, save and you're done.
So, as said, no problem if it stays on imperial units.  :)

To be honest, the mixture of metric and imperial units on the 737 is a prominent character trait and I hope it gets streamlined via 1.1. To run the one gauge in imperial and read the other one in metric units surely adds some excitement at times.
