Karamba3d - US HSS Sections - SI to Imperial Unit Conversion

I have concerns regarding unit conversion between SI and Imperial. Of particular concern is the use of HSS cross sections. The table provided by Karamba only lists US - HSS sections in terms of mm,cm, etc. When these cross sections are loaded into Karamba set to Imperial units, do the cross section properties get converted into Imperial units as well? If not, is there a version of the CrossSectionValues file that has these HSS shapes in Imperial units available for download?

I apologize for posting in multiple locations. It is my first time using this forum and it is unclear where one is supposed to post for customer support.
