Answer by josmiceli(9817)   (Show Source): You can put this solution on YOUR website!This is a problem in cancelling units (12.5 km)(1000 m/km)(100 cm/m) = 1.25*10^6 cm Notice on the left side, you have (km/km), and (m/m) These units cancel leaving you with cm. This string of cancelled units can be as long as needed to arrive at the chosen unit of measure.
