Unit History
The centimeter was created during the French Revolution as part of the metric system, defined as 1/100 of a meter. The foot is an ancient unit once based on the average length of a human foot, which varied significantly until it was standardized as exactly 0.3048 meters (1 ft) in 1959.
Common Uses
Converting centimeters to feet is essential for recording human height on international documents like passports and medical forms. It is also frequently used in interior design and construction when fitting metric furniture into spaces measured with imperial units.
Frequently Asked Questions
180 cm (70.9 in) is approximately 5.91 feet (1.8 m). To find this result, divide 180 by 30.48. In standard height notation, this is roughly 5 feet and 11 inches (1.8 m), which recent data indicates is a common tall stature for adults globally.
The exact conversion factor is 1 centimeter (0.39 in) equals 1 divided by 30.48 feet (0.3 m), which is approximately 0.03280839895. Since 1 foot (0.3 m) is defined precisely as 30.48 centimeters (12 in) by international agreement, this relationship is constant for all scientific and commercial applications.
170 cm (66.9 in) is equal to approximately 5.58 feet (1.7 m). You can calculate this by multiplying 170 by 0.0328084. This height translates to about 5 feet and 7 inches (1.7 m), a value frequently used in medical records and clothing size charts.
This specific measurement was established in 1959 under the International Yard and Pound Agreement to create a single, unified standard. By defining 1 foot (0.3 m) as exactly 30.48 centimeters (12 in), countries using different systems could maintain high precision in global manufacturing and trade.
No, 160 cm (63 in) is actually approximately 5.25 feet (1.6 m). Since 5 feet (1.5 m) is equal to exactly 152.4 cm (60 in), 160 cm is about 3 inches (7.6 cm) taller than the 5-foot mark. This conversion is often used in fitness and sports statistics.
