-To set the length of the calibration bar in millimeters,​ use the dot pitch number, rather than DPI, in my case .1799mm. ​ So - (478 pixels) X (.1799 mm per pixel) = 85.99 millimeters as the bar length.+To set the length of the calibration bar in millimeters,​ use the dot pitch number, rather than dpi, in my case .1799mm. ​ So - (478 pixels) X (.1799 mm per pixel) = 85.99 millimeters as the bar length.
