Why the use of Standard was made compulsory?

One of the main defects of unregulated market is the use of non-standard and arbitrary weight by arhatiyas and brokers. This was used to cheat the farmers. Lack of uniform standards in weights, will containing to keep marketing in unsatisfactory condition.

In 1939, the standard weights was passed under which the state government promoted the use of standard weight. But not the much head way could be made in this situation for different standard weights were used by different state. Later on in order to bring about uniformity  in weight, the government encoded legislation and adopted  the matrix system of measures, in 1958.

Since 1962 the use of metric weight has been made compulsory. Inspite of this, one still finds old measures still existing in some villages.
