Dimensional Analysis
When you divide a length in centimeters by the centimeter‑per‑inch ratio, the units cancel out, leaving you with inches:
[ \text{inches} = \frac{\text{centimeters}}{2.54\ \text{cm/inch}} = \text{length in inches} ]
This simple algebraic step ensures that the conversion is both accurate and universally applicable.
