About feet and inches
Multiply feet by 12 to get inches. A height of 5.5 feet is 66 inches, which is the same as 5 ft 6 in.
Inches are the unit most forms, clothing size charts and building plans in the US expect, so heights and room sizes given in feet often need converting before you can use them.

- 6 ft (a person 6 ft tall) is 72 in
- 8 ft (a standard US ceiling height) is 96 in
- 3 ft (one yard) is 36 in
