How to convert cm to feet
One international foot is exactly 30.48 centimeters. Divide centimeters by 30.48 for decimal feet; multiply decimal feet by 30.48 to convert back.
feet = centimeters ÷ 30.48
centimeters = feet × 30.48
1 international foot = 30.48 centimeters exactly
Example: 170 cm ÷ 30.48 = 5.577427… ft. That is 5 ft 6.93 in, or about 5 ft 7 in when rounded to the nearest whole inch.

Decimal feet, feet plus inches, and rounding
Decimal feet keeps the full measurement in one unit. Feet plus inches separates each whole foot and converts the remaining fraction of a foot into inches, so 5.5 ft equals 5 ft 6 in.
The decimal-place setting changes only the displayed rounding. The calculation always uses the exact relationship of 1 foot to 30.48 centimeters.
For a whole-inch height, round only the inch remainder at the end. For example, 170 cm is 5 ft 6.93 in, which rounds to 5 ft 7 in.
For a fit, clearance, or construction decision, keep the original measurement and use the tolerance required by the drawing, seller, or measuring instrument.
