How this calculation works
Uses international inch, foot, yard, and mile definitions. An inch is exactly 0.0254 meters and an international foot is exactly 0.3048 meters. Historical US survey units are not included.
Converted length = input × source unit’s meter factor ÷ target unit’s meter factor.
Your calculation, step by step
- 1 in = 2.54 cm.
- 1 × 2.54 = 2.54 cm.
