Where people use this

Feet: height in the US, room dimensions, construction. Centimetres: height, paper and screen sizes, clothing measurements. A 6 ft person is about 183 cm.

How we know this is right
The factor is fixed by the standards that define the units, not chosen — so it is exact, not a measurement:
1 cm = 0.03280839895 ft, so 1 ft = 1 ÷ 0.03280839895 = 30.48 cm.

Every value is carried to full double precision; the display is rounded.
