Mixed Units of Measurement in the Metric System

A quantity expressed in mixed metric units uses more than one metric unit of the same type simultaneously, such as $3$ meters $40$ centimeters or $2$ kilograms $350$ grams. Because metric prefixes are based on powers of $10$ , converting between mixed and single-unit forms involves straightforward decimal arithmetic:

Converting to a single unit: Express the larger-unit portion in the smaller unit using the appropriate power of $10$ and add the remainder. For example, $3$ m $40$ cm $= (3 \times 100) + 40 = 340$ cm. Alternatively, express in the larger unit: $3$ m $40$ cm $= 3 + 0.40 = 3.40$ m.

Converting to mixed units: Divide the measurement in the smaller unit by the conversion factor. For example, $4{,}725$ g $= 4{,}725 \div 1{,}000 = 4$ kg and $725$ g, so $4{,}725$ g $= 4$ kg $725$ g.

The base-ten structure of the metric system makes these conversions simpler than their US customary counterparts, which involve non-decimal conversion factors.
