    Try this formula:
    Mass Airflow (kg/sec) = Air Density (kg/m3) x Volume Airflow (m3/sec)
    Also:-
    Air velocity (m/sec) = Mass Air Flow (kg/sec) x [1/ {Air Density (kg/m3)}] x [1/ {Cross Section Area (m2)}]

    Your question is a little vague...why are you converting it, and what does M/SEC represent? It should only be important THAT it is flowing. The turbo works off the expanding superheated gasses in the exhaust, not the actual flow. If you have an EGR, the flow is regulated by the ECM. I guess I can't figure out why you need that conversion. If you could put in a blurb about the application, it would help me answer your question.
