Subtracting Mixed Metric Lengths to Find a Height Difference
To find the difference in height between two people when one measurement is given in meters and the other in centimeters, first convert both values to the same unit, then subtract.
Ryland is meters tall and his younger brother is centimeters tall. How much taller is Ryland?
- Choose a common unit: Since meters is the larger unit, convert centimeters to meters by moving the decimal point places to the left (because cm m): cm m.
- Subtract like units:
Ryland is m taller than his brother. The key step is ensuring both measurements share the same metric unit before performing the subtraction — the same principle used with US customary mixed units, but made simpler by the base-ten conversion.

A logistics manager is explaining to a new hire why the company uses the metric system for international inventory. The manager notes that converting measurements from mixed units (such as '5 meters 25 centimeters') into a single unit (such as '525 centimeters') is simpler than in other systems because the metric system is built on a specific mathematical foundation. Which fundamental property of the metric system is the manager referring to?
