All dialog boxes should have units mentioned.

It does not necessarily need to be mentioned after every input field in the dialog box.

For ratios or non-unitary numbers in the dialog box, a different color should be used in the background of the input field to indicate the number to be ratio or non-unitary.

Just adding something like 'units are in mm' or 'units are in millimeters' using noticeable font size and color will do the job.

However, when carrying out operations like bevelling/chamfering/filleting in the viewport by dragging the handles, the units must be mentioned beside the number in the viewport.
