Why use Height Converter?

Height conversions between metric and imperial units come up constantly — international forms, sports and medical records, or just comparing a height you saw quoted in the "wrong" unit. The math is simple in principle (divide by 2.54 to go from cm to inches) but easy to get slightly wrong by hand, especially the carry-over from inches to feet once the remainder passes 12. This converter handles both directions using the exact international inch (2.54 cm, standardized in 1959), so a value like 170 cm converts to 5'6.9" rather than a rounded 5'7" — useful when precision matters, with the rounded figure just as easy to read off.

Frequently asked questions

How do you convert cm to feet and inches?

Divide the centimeter value by 2.54 to get total inches, then divide by 12 to get whole feet, with the remainder as inches. 170 cm ÷ 2.54 = 66.9 inches = 5 feet 6.9 inches.

How many cm is 5'7"?

5 feet 7 inches is 67 inches, and 67 × 2.54 = 170.18 cm, which rounds to 170.2 cm.

What's the exact inch-to-cm conversion?

1 inch = 2.54 cm exactly, by international agreement since 1959 (the 'international inch'). This calculator uses that exact figure, not an approximation.
