What is the meaning of the unit [mrad] for a rotation?
In RSTAB, our standard rotation angle unit is "rad."
The results of the node deformations in Table 4.6 is displayed in "mrad," that is, milliradian.
The following general formulas are taken for the conversion of angular dimensions, using rad as unit for the arc length dimension:
From arc length dimension to degree: alpha = (180° / pi) * x
From degree to arc length dimension: x = (pi / 180°) * alpha
For the direct conversion of the unit "mrad" of the arc length dimension used in RSTAB:
From arc length dimension to degree: alpha = (180° / (pi * 1000)) * x
Please note that the values are in "mrad."
