The ancient Egyptian royal cubit (meh niswt) is the earliest attested standard measure.Cubit rods were used for the measurement of length.A number of these rods have survived: two are known from the tomb of Maya, the treasurer of the 18th dynasty pharaoh Tutankhamun, in Saqqara; another was found in the tomb of Kha in Thebes.
The setat was the basic unit of land measure and may originally have varied in size across Egypt's nomes. [20] Later, it was equal to one square khet, where a khet measured 100 cubits. The setat could be divided into strips one khet long and ten cubit wide (a kha). [2] [6] [37] During the Old Kingdom:
Detail of a cubit rod in the Museo Egizio of Turin The earliest recorded systems of weights and measures originate in the 3rd or 4th millennium BC. Even the very earliest civilizations needed measurement for purposes of agriculture, construction and trade. Early standard units might only have applied to a single community or small region, with every area developing its own standards for ...
In Ancient Egypt it was the basic unit of subdivision of the cubit. [1] On surviving Ancient Egyptian cubit-rods, the royal cubit is divided into seven palms of four digits or fingers each. [3] The royal cubit measured approximately 525 mm, [4] so the length of the ancient Egyptian digit was about 19 mm.
One official government standard of measurement of the archaic system was the Cubit of Nippur (2650 BCE). It is a Euboic Mana + 1 Diesis (432 grams). [ citation needed ] This standard is the main reference used by archaeologists to reconstruct the system.
Those that were larger, in increasing order of size, included the modius (מודיא), [39] geriwa (geriwa), garab (גרב). Of unidentified size were the ardaba (אדרב), the kuna (כונא), and the qometz (קמץ); the latter two of these were said to equate to a handful. Some dry measures were used for liquids as well, e.g. se'eh.
A measuring rod is a tool used to physically measure lengths and survey areas of various sizes. Most measuring rods are round or square sectioned; however, they can also be flat boards. Some have markings at regular intervals. It is likely that the measuring rod was used before the line, chain or steel tapes used in modern measurement. [1]
It is thus a measure equivalent to our modern cotangent of the angle of slope. In general, the seked of a pyramid is a kind of fraction, given as so many palms horizontally for each cubit of vertically, where 7 palms = 1 cubit. The Egyptian word 'seked' is thus related [in meaning, not origin] to our modern word 'gradient'. [2]
