The unit is always in the units of the dataset/projection. For Lat Long this unit will be in degrees, for meters it will be meters etc. As a rule it's best to reproject to a local coordinate system when performing geometric operations.
So are you saying for my data. All the transformers that are linked to LL84 Coordinate system would be in lat long, while those transformers that are linked to Hong Kong80b.Grid System would be in meter?
May I ask how do I reproject to local coordinate system? I have no clue how to do it.
My final goal is that I have to set the snapping distance in meter value.
Thank you for your help. :)

You can use the Reprojector to reproject from LL84 to your meter grid.
