(a) Interpretation: The number of meters in one kilometer is to be calculated. Concept introduction: The conversion of one unit into another can be done use of a proper conversion factor. Conversion factors are the ratios that relate the two different units of a quantity. It is also known as dimensional analysis or factor label method. In the unit conversion problems, the given information is multiplied by the conversion factors to obtain the desired information. The unit conversion can be done as follows: ( beginning unit ) ( Final unit beginning unit ) = Final unit
