Maund (unit)

[2][3] In British India, the maund was first standardized in the Bengal Presidency in 1833, where it was set equal to 100 Troy pounds (82.28 lbs.

In Nepal's southern plains one Mann equals 40 kilograms and is generally used to measure agricultural output.

During the reign of Alauddin Khalji of the Delhi Sultanate, 1 mann was roughly equivalent to 15 kg.

[7] Prinsep (1840) summarizes the evidence as to the weight of the mun (later "maund") during the reign (1556–1605) of Akbar the Great,[8] which comes from the Ain-i-Akbari written by the vizier Abu'l-Fazl ibn Mubarak (anglicized as "Abul Fuzl").

[8] The jilály, a square silver rupee coin issued by Akbar, was said by the Ain-i-Akbari to be 11+1⁄4 mashas in weight: surviving jilály and other Mughal rupee coins weigh 170–175 Troy grains (11.02–11.34 g), so the masha, defined as eight ruttees, would be about 15+1⁄2 grains (1 g).

[10] However, in yet another section of the Ain-i-Akbari, the dam is said to be "twenty mashas seven ruttees": using this definition would imply an Imperial mass of about 47 lb.

The results were published as an appendix to the second edition of Kelly's Universal Cambist (1831), and later as a separate book entitled Oriental Metrology (1832).
