how u can obtain in according to any code if u want :O
This scale factor strongly depends on the response spectrum function type as well on code specific additional coefficients and units used during input.
Please see attachment. Although it is elaborated for specific case you may find it useful.
Most codes used different multipliers ( Zone factor, Importance factor, behavior factor etc.) and diff. type of normalized response spectrum functions - normalized to g or ag, linear or nonlinear type resp. spectum. ;
Always check for the consistency of units:
Response Spectrum Functions * sf = Sa(T) - m/s2
Sa(T) is a response spectrum acceleration (without any modifications);
Sf = code prescribed multiplayers *factor(s) used to normalize resp. spectrum function ( if any)
