How to use cellZoneInjection, "numberDensity", anyone can help ??

Hi all, I have tried to use cellZoneInjection to put particles in my case but I'm not understanding the behavior of the "numberDensity".
I was in the believe that the numberDensity was the number of particles per cell. Or the number of particles for the cellZone.
But reading the source file .C, it looks like it is "the number of particles per cubic meter".
Is it right ??
So, my question relies. If I provide: flowrate (kg/s), diameter (distribution) and the density is know.. why the hell do I need some particle density O.o ??
injectionModel cellZoneInjection; //Inject particles at the cloudZone
numberDensity 5.87E+06;//Number density of particles in one cell
massFlowRate 0.0024585;//Mass per second
parcelBasisType mass;//Reference propertie
cellZone myCloud;//Cell zone to realize injection
SOI 1e-6; //Start of injection
U0 (89.4 0 0); //Initial particle velocity
sizeDistribution //Used to infere the diameter
Is that right ?? Can someone please confirm the behavior.
