One pood was equivalent to approximately 16.38 kilograms or 36.11 pounds. It was a standard measure for a range of goods, from agricultural produce to industrial materials.

Additionally, smaller units like the "funt" (equivalent to roughly one pound) were also in use. [1]

79 Kaabu present Inferred -
The following suggests the existence of a standardised weighing system among the Mande at this time, especially as they would have likely traded both with the Akan of Ghana and Arabs from North Africa. "For weighing gold-dust, the standard based on the Roman ounce and the solidus was retained by the Arabs, and survived until the nineteenth century in the Western Sudan. It was also adopted by the Akan of Ghana and Ivory Coast, who made it the basis of their weight-system from about 1400 to 1900." [1]

80 Dutch Empire present Confident -
"These towns all maintained their own local sets of weights and measures. The Amsterdam grain last was the national, indeed the international volume measure for wholesale transactions in wheat and rye, but every city subdivided the last into its own sub-measures: the zak (sack), the mud, the schepel (akin to the bushel), etc. Similarly, every town maintained its own standard of weight. The Amsterdam pond was adopted by many places, especially around the Zuider Zee, but a lighter pond, apparently derived from the Cologne weight system, was also common. [...] Finally, cities varied in the specific types of bread they allowed in their jurisdictions. For all these reasons, the regulatory regime of each city was a little world of its own: its own types of bread, its own weights, its own grain measures. A necessary and often frustrating aspect of this study, has been reducing all these differences to the metric system, which was not fully adopted by the Kingdom of the Netherlands until 1821." [1]

81 Kingdom of Jimma present Inferred -
The quote below discusses the general systems of measurement in Ethiopia, suggesting that the weight measurements were likely present in the Kingdom of Jimma. “Three basic types of weight concepts may be discerned: firstly, vague ideas of heaviness or lightness obtained merely by lifting objects in the hand, or even by estimating their weight by sight; secondly, basic, but relatively crude concepts such as the porter, donkey, mule and camel-load, which, by reason of their simplicity, may be compared with fundamental measurements in other fields like the length of the human arm, the area ploughed by an ox in a day or the amount held in the hand; and, thirdly, more accurate measurements based on the use of some kind of scales, steelyard or other weighing apparatus.” [1]

82 Adal Sultanate present Confident -
"Islam was unifying element in much of the Indian Ocean, especially on both sides—the east African coast and the Malay world. The east African societies relied on Islam to help create their world since their identity derived not only from commercial links with co-religionists but on specific modes of social and commercial behavior. The Muslim religion gave prescriptions as to everyday conduct. The Koran had specific admonitions on fair practice in the market place. The Koranic injunction to have balance scales led to the appearance of a market inspector called the muhtash whose specific job was to oversee local transactions and check weights and measures among other duties."

96 Kingdom of Gumma present Inferred -
The quote below discusses the general systems of measurement in Ethiopia, suggesting that the weight measurements were likely present in the Kingdom of Gumma. “Three basic types of weight concepts may be discerned: firstly, vague ideas of heaviness or lightness obtained merely by lifting objects in the hand, or even by estimating their weight by sight; secondly, basic, but relatively crude concepts such as the porter, donkey, mule and camel-load, which, by reason of their simplicity, may be compared with fundamental measurements in other fields like the length of the human arm, the area ploughed by an ox in a day or the amount held in the hand; and, thirdly, more accurate measurements based on the use of some kind of scales, steelyard or other weighing apparatus.” [1]

99 Isaaq Sultanate present Inferred -
"Islam was unifying element in much of the Indian Ocean, especially on both sides—the east African coast and the Malay world. The east African societies relied on Islam to help create their world since their identity derived not only from commercial links with co-religionists but on specific modes of social and commercial behavior. The Muslim religion gave prescriptions as to everyday conduct. The Koran had specific admonitions on fair practice in the market place. The Koranic injunction to have balance scales led to the appearance of a market inspector called the muhtash whose specific job was to oversee local transactions and check weights and measures among other duties."

100 Classical Ife present Inferred -
The phrase "standard measurements of beads", in the following quotes, implies the possible existence of a measurement system, at least one used to measure beads in terms of quantity and/or quality. "We are short of evidence on whether glass beads evolved to serve as a standard currency, especially as a means of pricing. However, strings and other standard measurements of beads were likely used for purchasing high-value products and services." [1]

102 Kingdom of Cayor present Inferred -
Within the trans-Saharan trade networks which the Kingdom of Cayor was a part of, the mithqal was a pre-colonial measurement system that was used up until the nineteenth century. “The salt bar was to regional western African exchange what the gold mithqal was to international trade. But the mithqal was a considerably more stable measure across the markets of African and the Middle East, from Timbuktu to Kumasi, Marrakech, Tripoli and Cairo […] It was the only precolonial western African measure, besides the ratl used for ostrich feathers, corresponding to an actual weight as opposed to a quantity. Silver was also weighted in mithqals.” [1]

Cambonneau writes that from December 1675 to March 10, 1676, he occupied himself with the single aim to resupply the island after the departure of the Biert with ‘millet of which we had great need for the great number of captives which we traded everyday.’ The transport of millet was also ‘made on little boats. They carry a hundred matas of the big moule of millet, which is the measure of the country, which we use at the settlement to accommodate ourselves to them. This comes to seventy barrels or thereabouts.’” [2]
