Ancient Arabic units of measurement

The old Arabic system of measurement is based on the Persian, which in turn is based on the Mesopotamian system. Since the Roman system of measurement is about the ancient Egyptian, also derived from Mesopotamian dimensions, there is a precise ratio of 25: 27 to the Roman foot.

• The scientifically arbitrary definition set value of the Nippur cubit is 518.616 mm A Roman foot has a length of 4/7 Nippur Ellen The Arab foot has a length of 27/25 Roman feet This results in a theoretical length of the Arabian rate of exactly 108/175 Nippur Ellen = 320.06016 mm results in ≈ 32 cm
