Change disply to inches only

This new version of Sketchup Pro (2020.1.228) insists on displaying measurements in feet and inches. I want it to only display in inches. I go to Window/Model Info/Units and have selected Architectural/Length is grayesd out but says Inches and Display precision is down to 1/64th. No matter what I have tried, tape4 measure will only display in feet and inches. Help
