The basic conversion
One inch equals exactly 2.54 centimeters. To convert inches to centimeters, multiply by 2.54. To convert centimeters to inches, divide by 2.54. Feet are simply groups of 12 inches.
For example, 5 feet 7 inches is 67 total inches. Multiplying 67 by 2.54 gives 170.18 centimeters, which is commonly displayed as about 170 cm when rounded to the nearest centimeter.
Why conversions can look slightly different
Height listings are often rounded. A person listed as 170 cm may convert to approximately 5 feet 7 inches, while a more precise measurement could display as 170.2 cm. Those labels can describe essentially the same height at the level of precision most people use.
Standii keeps the stored height in centimeters and converts it for display when you choose feet/inches. That gives the comparison wall one consistent internal measurement while still making the result easy to read.
Compare precision, not just labels
When two people are close in height, the rounding convention matters. A one-inch difference is about 2.54 cm, so a pair of profiles with the same rounded label may still be slightly different in the underlying data.
If precision matters, check the centimeter value and any source or verification note on the profile. For casual comparisons, the rounded feet/inches label is usually easier to understand and more than sufficient.
