ODF 1.1 has not specified the syntax of datatype 'angle'. Since ODF 1.2 it is specified as double with unit "deg", "grad" or "rad", or without unit. The unit-less value is specified to be in degrees. In all places, where LibreOffice reads angle values, it cannot read units. The cases where LibreOffice writes 1/10 of a degree values instead of degree are addressed in bug 161327. This bug report is for the cases where LibreOffice correctly writes unit-less values in degree, but is not able to read units. A list (hopefully complete) of those cases is in bug 161327#c8.
I have started work in https://gerrit.libreoffice.org/c/core/+/169360. It is not complete yet, but shows what I want to do. The still missing cases are: StartingAngle (chart), TextRotation (charts), RotateAngle (table cell), CharRotation, TextRotateAngle (custom shape), RotateAngle (extruded custom shape), Skew (extruded custom shape). CaptionAngle would be affected too, but its implementation is incomplete.
Regina Henschel committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/9f62c7a0f2333d1b7d179a43b3b0341dba7554a1 tdf#161483 enable LO to read ODF angle units It will be available in 25.2.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
Not totally fixed, see the list in comment #1. But I will not have much time in the next days, so I've removed me from "Assigned".
