How It Works
Centimetres (cm) are part of the metric system, used in most countries worldwide. Inches (in) are part of the imperial system, used primarily in the United States and informally in other English-speaking countries.
Exact Conversion: 1 inch = 2.54 centimetres (this is a defined exact value, not an approximation).
CM to Inches: Inches = Centimetres ÷ 2.54. Example: 30 cm ÷ 2.54 = 11.81 inches.
Inches to CM: Centimetres = Inches × 2.54. Example: 6 inches × 2.54 = 15.24 cm.
This conversion is commonly used for clothing sizes, screen sizes (TV/monitor diagonals), height measurements, and design specifications.
