When using Raster Based Terrain Analysis on QGIS for creating a slope layer, what units are the used in the output? Degrees or %?

If you create a slope layer from Raster > Terrain Analysis > Slope, the output layer will have degrees as units of measurement.

Instead, using the Slope GDAL tool from the Processing Toolbox will allow expressing the slope as a percent, instead of degrees (they are the default unit):

There is also the Slope, aspect, curvature SAGA tool from the Processing Toolbox, which allows expressing the output using radians too (but I never tested it):
