There isn't a need with Cura to import a file in mm. If your stl file is in inches, and you import into Cura all you have to do is scale it 2540% This is how I have been doing it. Works perfect. This is similar to converting inches to mm. Multiply the inch dimension by 25.4 and you get mm. - .5 inches x 25.4 = 12.7mm
