It remains the dominant unit for aviation altitude worldwide, even in metric-dominant countries. feet are commonly used in Human height (US/UK/Canada), Aviation altitude (worldwide), Real estate square footage, and Lumber length, Boat length.
A standard subway sandwich is nominally 1 foot long.
About millimeters
The millimeter (mm) is the standard unit for engineering and manufacturing precision. Defined as one thousandth of a meter, it allows for accurate specifications without resorting to fractions. In the late 19th century, the adoption of the millimeter in industrial design helped standardize interchangeable parts, a key driver of modern mass production. It is also the standard for reporting rainfall in meteorology. millimeters are commonly used in Engineering blueprints, Smartphone dimensions, Jewelry sizing, and Medical instruments, Meteorology (rainfall).
