From Indus Valley to Modern Tape Measures
Considering that the known history of measuring extends at least as far back as five thousand years, it might be surprising to discover that the invention of tape measures is less than one hundred and fifty years old. A sophisticated form of measurement was used among the Indus Valley civilization from 3,000 to 1,500 BC, as well as among the ancient residents of Mesopotamia and Egypt.
In the Indus Valley, located in northwest India, people were known to measure length, mass and time, with tremendous accuracy, with the smallest unit of division, found on an ivory scale, being 1/16th of an inch, the smallest unit ever found in the Bronze Age . In fact, the units of measurement we know as the inch and the yard stick were also used in the Indus Valley, measuring 33 inches in length (although at the time is was called variously a hasta, a kishku, or muzam).
Most other means of measurement were based on parts of the body, the first real tape measure. Early records from Babylon and Egypt, as well as the Bible, tell us that these measurements were conducted using the finger, hand, or forearm. However, the first U.S. patent for a tape measure was in 1868, on July 24, in 1868, by Alvin J. Fellows. Gradually, a great variety of professional tape measures came into use, winning out over the collapsible ruler.
