Frequently Asked Questions
How do I convert centimeters to feet and inches?
Divide the centimeter value by 2.54 to get total inches, then divide the total inches by 12 to get feet with the remainder as inches. For example, 175 cm = 68.9 inches = 5 feet 8.9 inches. This converter does this calculation automatically and displays the result in the feet+inches format.
What is the feet+inches input mode?
The feet+inches mode lets you enter a height using the common American format of separate feet and inches values. For example, instead of entering 70 inches, you can enter 5 feet and 10 inches. This is how height is typically expressed in everyday conversation in the United States.
How tall is the average person?
The global average height is approximately 171 cm (5 ft 7 in) for adult males and 159 cm (5 ft 3 in) for adult females. However, averages vary significantly by country. For example, the average male height in the Netherlands is about 183 cm (6 ft 0 in), while in Guatemala it is about 164 cm (5 ft 5 in).
