The SI base units for length is meter (m) and for time is seconds (s).
The given ratio is 

Converting mm/s to m/s as:
Since, 1 mm/s = 0.001 m/s
So, 
Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of
to three significant figures and answer in SI units is
.
