lattice velocity meaning

After a lot of expermiments, in my head appered some confusion.
For example:
u_{lb} = 0.1
then we can say that
‘fluid moves 0.1 lattice cells per lattice step’

but what about dt_{ph}, exactly saying
each cycle in LBM algorithm means dt_{ph} or dt_{ph}/10 ??

I think that dt_{ph} as this results from equations using to unit conversion.
Am I wrong?
Thanks for help
