Evolution of measurement tools

During our History there had been different measurement tools depending on the materials and necessities that society had in each moment. At first the human body was used as a reference, but this came with a problem, everyone had a different length, so it was not a standardized measure of unit. An example of these units is the length measurement units such as the inch or the foot.

Afterwards there was recognized the necessity of unifying the measurement units in order to be able to have the same tool as instruments, and the International Measurement System was created. This was a huge advance in the metric area as there was now a standardized measurement system.

An example of this is the metric system used nowadays.

This is a very interesting video showing different measurement tools and their evolution towards our actual measurement system.

Have fun and use different tools!
