US and SI unsteady flow problem

[geoyannis]

hello there, I am new to the software, I have completed an unsteady flow simulation in US units (around 14000 cfs on the peak of the hydrograph) and I get as a result a perfect flood similar to the real scenario. Nevertheless if I create the same project in SI units (around 400 m3/s on the peak of the hydrograph) the flood doesn’t cover more than 1/3 of my basin… it is like if even though the units in m3/s seem to be correct in the unsteady flow data they are still in cfs when the final result is obtained in ras mapper…

My 2d mesh is also in the equivalent metric.

Any thoughts? Thanks very much in advance!

After computing, I also get these values in the view section>stage and flow hydrographs.

the flow hydrograph remains in cfs for an unknown reason, instead the other parameters are in SI…
