1 inch (in) is equal to exactly 2.54 centimeters (cm) — the international standard conversion factor for inch to cm calculations (defined by the International Yard and Pound Agreement).
The length L in centimeters (cm) is equal to the length L in inches (in) multiplied by 2.54:
L(cm) = L(in) × 2.54
