FAQ
Unit Converter FAQ
How many centimeters are in an inch?
One inch is exactly 2.54 centimeters.
Can I convert 5 ft 8 in to cm?
Yes. Smart Input recognizes feet-and-inches and converts the combined measurement.
Why show feet and inches?
A decimal foot result can be less familiar, so the tool also gives a human-friendly feet-and-inches form.
