One centimetre equals exactly 0.3937 inches, or equivalently, 1 inch equals exactly 2.54 cm — an international standard since 1959. To convert centimetres to inches, divide by 2.54.
Formula: inches = cm ÷ 2.54
- 30 cm = 11.81 inches (length of a standard 30 cm ruler)
- 180 cm = 70.87 inches ≈ 5 ft 11 in
- 55 cm = 21.65 inches (a 22-inch screen diagonal)
- 100 cm = 39.37 inches
In the UK, height is still commonly given in feet and inches even though the metric system is official. Screen sizes (TVs, monitors, tablets) are quoted in inches. Tyre sizes include a rim diameter in inches. Many older buildings have dimensions recorded in imperial units.
The UK uses a hybrid system — official measurements are metric, but many everyday uses remain imperial. Height is typically given as "5 foot 11" rather than 180 cm. Estate agents list room sizes in both metres and feet. Road distances are in miles; speeds in mph.
