Many of the '''ancient weights and measures''' used throughout history are variations on a common theme sharing the same system. Despite a number of different civilisations making adjustments to serve their own purposes the accuracy and agreement of definitions improved over time. | |||

Measurements that are used to define property are often used to impose taxes or tithes resulting in there being one measure for ordinary transactions and another for royal or religious transactions. Though throughout history people and their various representatives in guilds and lobbys, have been very scrupulous in defending the value of their possessions, governments and religions are even more scrupulous about getting their cut. | |||
The first measures were the lengths of the ditches that bordered and defined the fields. Since people tend to pace off a distance differently, knotted cords were used to measure their sides and cord stretchers became the first surveyors. | |||

The people of the ] (ca. ]) achieved great accuracy in measuring length, mass, and time. They were among the first to develop a system of uniform weights and measures. Their measurements were extremely precise. Their smallest division, which is marked on an ivory scale found in ], was approximately 1.704 mm, the smallest division ever recorded on a scale of the ]. The ] system was used. ]n ]s followed the decimal division of measurement for all practical purposes, including the measurement of mass as revealed by their hexahedron weights. Weights were based on units of 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, 200, and 500, with each unit weighing approximately 28 grams, similar to the ] or ]<!--Greek or Roman?-->, and smaller objects were weighed in similar ratios with the units of 0.871. | |||
