Height Converter

Total inches = feet x 12 + inches. Then cm = total inches x 2.54. Example: 5ft 11in = (5 x 12) + 11 = 71 inches. 71 x 2.54 = 180.34 cm. Shortcut: roughly 1 foot ≈ 30.48 cm, 1 inch ≈ 2.54 cm.

US average: Men 5ft 9in (175.3 cm), Women 5ft 4in (162.6 cm). Global averages vary: Netherlands men average 6ft (182.9 cm), Bolivian women average 4ft 11in (149.8 cm). Heights have been increasing over the 20th century due to improved nutrition and healthcare.

Divide cm by 2.54 to get total inches. Then floor(total inches / 12) = feet, and total inches mod 12 = remaining inches. Example: 180 cm / 2.54 = 70.866 inches. 70.866 / 12 = 5 feet remainder 10.866 inches ≈ 5ft 10.9in.

Culturally varies by country. In the US: men above 6ft (183 cm) are often considered tall, while 6ft 2in+ (188 cm) is very tall. Women: above 5ft 8in (173 cm) is often considered tall. Medically, tall stature means height above the 95th percentile. Extremely tall heights may be investigated for growth hormone disorders.

The metric system (centimeters, kilograms) is used in most countries worldwide. The US, Liberia, and Myanmar primarily use the imperial system (feet, inches, pounds). Medically and scientifically, metric is standard globally. Many US-born individuals know their height in feet/inches but have to look up the centimeter equivalent.
