The Myanmar nationals of ancient times have widely accepted the weights in the shape of Hintha (Brahming Duck) in trading consumer goods as well as weighing the silver.

Among many kinds of weights in various animal shapes such as Nayar (a mythical animal) Hintha (Brahming Duck) Horse and Ducks, the Hintha Weights could be seen most commonly today.

The Hintha weights are still in use in trading at present day and we can also see some of them in museums. The public is donating the Hintha weights to the museums and pagodas. The smallest Hintha weight weighs two annas equivalent to 0.0045 pound and the largest up to 500 ticals 18 pounds. The reason why the Hintha weights are commonly used could be that the Myanmar nationals value it more than the other weights in animal shapes.

There are many kinds of Hintha weights in different forms. Earlier, the weight was issued in the form of a duck and later floral designs appeared on the weight so it was called Pan Hintha (Floral Brahminy Duck) weight.

The bronze weights which might be the most ancient in Myanmar were discovered in excavating the site no.15 of the old Beikthano city. Researchers have said that the weights might have been in use between the 1^st and 2^nd AD.

It was seen that Hintha shapes were marked on either in front or at the back or on either sides of the base stand of the weight. There are markings of stars in front of the base stand of some weights made of lead. In some Hintha weights it was seen that the mother of Hintha was holding firmly the son Hintha with its teeth. It seemed similar with that of the Hintha shape holding a flower with its teeth.

Successive ancient Myanmar monarchs had valued the Hintha weights and made use of them for keeping only one system in equal weighing by scales in trading.
