# Agrometrology

Agrometrology units of measurements and weights of agricultural commodities, and inputs in mass, volume, land area, and number. It is interesting to note that bangladesh has its own metrologies from time immemorial for local use by farmers and businessmen. Different districts have their own agrometrology systems greatly varying in nomenclature and measuring units. However, the Government of Bangladesh introduced the metric system of measures from 1982 through an Ordinance.
