Good to know
Height in feet and inches: multiply the feet by 12 and add the inches. 5 ft 7 in is 5 × 12 + 7 = 67 in; 6 ft 2 in is 74 in. Many medical and sizing forms want total inches.
Decimal feet to inches: multiply only the decimal part by 12. 5.75 ft is 5 ft plus 0.75 × 12 = 9 in, so 5 ft 9 in (69 in). A tape that reads 0.1 ft is 1.2 inches, which is why survey tapes look odd next to a carpenter's tape.
Lumber: an 8 ft board is 96 in and a 10 ft board 120 in. Wall studs for an 8 ft ceiling are usually sold precut at 92-5/8 in, because the plates and drywall make up the rest.
