About the foot and the inch
The foot is divided into 12 inches and is used for personal height in the US and UK, building dimensions in the US and aircraft altitude worldwide: airliners cruise at roughly 35,000 feet.
The inch is an imperial and US customary unit equal to one twelfth of a foot. It is used for screen sizes, tire and wheel dimensions, plumbing pipes, lumber and many tools in the US, UK and Canada.
One foot equals 12 inches, which makes the foot the longer unit of the two.
