Where it is used: Building heights, room dimensions, aviation altitude worldwide, and personal height in the US and UK.
Worth knowing: The US survey foot, very slightly longer, was used in land surveying until it was officially retired at the end of 2022.
What is a centimeter?

Feet vs Centimeters
The foot is an imperial unit while the centimeter is a metric unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
