Do sig figs apply to conversions?
The conversion factors do not count for sig figs because they are exact values and are not measurements that is why it does not matter.
How many significant figures does a conversion factor have?
We treat conversion factors as having an infinite number of significant figures and we remember that the minimum number of significant figures in the factors going into the average speed in m/s was four. Thus, our final answer in this case should also have four significant figures.
