RC PLATE DEFLECTION IN STAAD PRO CE

1. Iam designing a concrete slab supported on two beams,the deflection results obtained in staad pro (post procssing) are given in length unit,how do i compare these results with allowable deflection because the alowable deflection according to BS 8110  (Table value 3.9 X Modification factor) which do not have units.

My slab is only supported by two beams, this kind of slab can not be designed in RCDC, in such case i have mesh my slab plate, and design it in Staad pro C.E work flow.

The displacement which i consider is maximum nodal displacement, and remember in workflow of Staad Pro C.E plate deflection check is not performed, we have to check it manually. That is where iam asking how do we compare the results of displacement of nodes with the allowable deflection
