One inch equals exactly 2.54 centimeters — a precise definition adopted internationally in 1959. Multiply your inch value by 2.54 to get centimeters.
Formula: cm = inches × 2.54
- 72 inches = 182.88 cm (6 feet tall)
- 65 inches = 165.1 cm (5 ft 5 in, close to average US female height)
- 8.5 × 11 inches = 21.59 × 27.94 cm (US Letter paper)
- 17 inches = 43.18 cm (standard laptop screen)
You'll need inches-to-cm conversion when ordering custom furniture from European manufacturers, filling out international forms that ask for height in cm, or shipping packages to metric countries. Architects and engineers regularly convert blueprint dimensions when collaborating internationally.
US Letter paper (8.5 × 11 in) differs from the global A4 standard (21 × 29.7 cm). American television screen sizes are always in inches — a 65-inch TV has a 165.1 cm diagonal.
