How this was calculated
Conversion
1 cm = 0.39370079 in
180 cm = 70.866142 in
Exact factors
Both units defined in m
1 cm = 0.01 m; 1 in = 0.0254 m
Exact conversion factors
Since 1959 the international yard is defined as exactly 0.9144 m and the pound as exactly 0.45359237 kg. Every imperial and US length and weight here derives from those two numbers, so conversions are exact rather than rounded tables: 1 inch is exactly 2.54 cm and 1 mile exactly 1.609344 km.
Temperature is different: the scales have different zero points, so converting needs an offset as well as a ratio. See the temperature converter.
Questions people ask
Is weight the same as mass?
In everyday use, yes: kilograms and pounds here measure mass. In physics, weight is a force measured in newtons.
Can I convert from the home page?
Yes. Type something like "5 ft to cm" or "60 mph in km/h" into the quick answer bar.
