I am using the SST model in SU2 for computation of turbulent flow over a flat plate. The free-stream turbulence intensity of the fluid-flow I am computing is 3%. In the config.cfg file, whether I have to provide the free-stream value of turbulence intensity ("FREESTREAM_TURBULENCEINTENSITY") as 0.03 or 3.0?

If you check transition plate tutorial on SU2 website it shows 0.18% turbulent intensity to be entered as 0.18.
https://su2code.github.io/tutorials/...al_Flat_Plate/

But if you check the value of Turb. Kin. Energy when you run the simulation it will use 0.18 in following equation. (Turb. Kin. Energy = 3/2 (U I)^2). I feel considering I = 0.18% it should be entered as 0.0018.

It will be great if someone else can confirm about this confusion.

It is indeed like you are saying, 0.18% has to be entered as 0.0018. Thats a mistake in the tutorial case ...
