I recommend ! In the work I used a conventional mechanical caliper. Over time, the accuracy became not the same . I bought an electronic one on the market. With this barbell it is much more convenient to take measurements. The scale is applied both on the bar itself and the electronic display is present. In general, convenience in measurements is guaranteed. On the reverse side are indicated both in millimeters and in inches.
Check out the pictures I added to my review to get a better understanding of my perspective.
