Farrand's new design was a concave/convex tape made of metal which would stand straight out a distance of four to six feet. This design is the basis for most modern pocket tape measures used today. With the mass production of the integrated circuit (IC) the tape measure has also entered into the digital age with the digital tape measure. Some ...

He proposed calling his base unit of length a "foot" which he suggested should be either 3 ⁄ 10 or 1 ⁄ 3 of the length of a pendulum that had a period of one second—that is 3 ⁄ 10 or 1 ⁄ 3 of the "standard" proposed by John Wilkins over a century previously. This would have equated to 11.755 English inches (29.8 cm) or 13.06 English ...

Although link chains were later superseded by the steel ribbon tape (a form of tape measure), its legacy was a new statutory unit of length called the chain, equal to 22 yards (66 feet) of 100 links. [8] This unit still exists as a location identifier on British railways, as well as all across America in what is called the public land survey ...
Brannock spent two years developing a simple means of measuring the length, width, and arch length of the human foot. He eventually improved on the wooden RITZ Stick, the industry standard of the day, [ 2 ] patenting his first prototype in 1925 [ 3 ] and an improved version in 1927. [ 1 ]
