Thank you for your very quick reply. I was using an older version of Affinity Photo (AP). I (since my writing) have upgraded to "AP" version 1.6.6. This is no longer an issue, or problem. the units selector is conveniently located right on the top menu bar. Works beautifully now: I can easily change the rulers to any mode quickly. Sorry for my "Stressed " sounding Post. Love the Macro Download! I'll have to look if there is a repository of more of these (very cool!).... Starting to love this software.... (by, by Photoshop :-)
