Dimensional coordination

Ancient measure systems were based on the human limb sizes and body’s capacities. These were function-related measures such as: foot size and walking, thumb and width, fingers and numbers, palm and holding capacity, head load or horse power and carrying capacity, etc.

In a series of measure units, the sub units, though body related, were nearly independent. The interrelationships between sub units were simple but enforced. Various measures’ series were mutually incomparable and to an extent incompatible.

Across the world there were innumerable measure systems, but the Foot-Pound system became dominant due to extensive colonization by the British Empire.

The Metric System (created in France post Revolution period) was an abstract system with a Mathematical Order. It had the advantage of Logical Fractions. All measure units were divisible to 10X. But (early) Metric system had several sub units, many of which had no effective use. For some people the rationale of Metric system was too contrived as its scale did not relate to human body and its parts-whole-parts relationship.

In thePost Industrial Revolution‘ period, trade and industry all over the world recognized the need for a Universal Dimensioning Discipline. At that time better coordination was also required for conversion and transmission from old measurement systems to the new SI system of measurements. First worldwide understanding emerged in the adoption of SI as the Universal Measure System.
