Unit definitions
What is a foot?
The foot is an imperial and US customary unit equal to exactly 0.3048 metres, or twelve inches. It remains the standard unit for human height, building heights, and aviation altitude in the United States and United Kingdom. Three feet make one yard.
What is a micrometer?
The micrometre, or micron, is one millionth of a metre. It is used for microscopic measurements such as cell sizes, bacterial dimensions, semiconductor features, and the thickness of coatings and fibres. A human hair is roughly 50–100 micrometres across.
