About converting pad corner radius from percentage into mm or inch

Hi.
The pad corner radius is given by Altium in %.
The datasheets give it in mm or inch.
How would it be possible to make the conversion?
Thanks

I found the answer:
The value in Altium is a percentage of half of the shortest side of the pad. As such, a value of 0% corresponds to a rectangular pad, and 100% to a circular pad.
So for example, if the shortest side of the pad is 0.3 mm and you want a corner radius of 0.05 mm, please divide 0.05 by 0.15 giving 30%.
That's all folks!

Glad you figured it out.
Something I've done in the past to figure things out is to create test cases and then use Altium Designer's measurement tools to see if I can figure out what it's doing, or what it's supposed to be doing 😉
