About this converter
The maund (also written mon, mun, or মণ) is the traditional bulk weight unit of Bengal, Bangladesh, and the wider eastern Indian subcontinent. The British Indian standard maund — still in everyday use across Bangladesh and West Bengal — is defined as 100 troy pounds = 37.3242 kilograms. The maund is divided into 40 seer (≈ 0.9331 kg each), and each seer is further divided into 16 chhatak (≈ 58.32 g each).
Conversion formula
Kilograms = maund × 37.3242. Reverse: maund = kg / 37.3242. For seer: kg = seer × 0.9331, or seer = kg × 1.0717. For chhatak: grams = chhatak × 58.32.
Worked example
A 5-maund sack of rice weighs 5 × 37.3242 = 186.62 kg. The same sack expressed in seer is 5 × 40 = 200 seer, or in pounds, about 411.4 lb.
How maund relates to other weight units
1 maund (Bengal) ≈ 82.286 pounds. 1 seer ≈ 2.057 pounds, or about 933 grams. The chhatak (1/16 of a seer) was traditionally used for retail purchases at the village haat — half a chhatak ≈ 29 g was a common rice scoop.
Regional variation
The Bengal / Bangladesh maund (37.3242 kg) is the most commercially active value today. Other regional maunds historically existed — the Pakistani maund (37.324 kg, identical), the Indian maund of 100 sherras (≈ 37.32 kg), and a smaller Bombay maund (≈ 12.7 kg). This converter is calibrated to the Bengal standard, which matches Bangladesh agricultural markets and West Bengal retail.
