The traditional English apothecaries' system was a subset of Roman weight system except that Roman libra (pound) was slightly lighter. In 1858 apothercaries' system was officially abolished in in the U.K. in favour of the standard Avoirdupois system. However, in the United States the apothecaries' system remained in use until 1971, when it was officially abolished in favor of the metric system.

Indian units (Akbar system)

The first uniform system of units was introduced in India by the third imperor Akbar I in 16th century. Before him weights and measures varied from region to region. Unfortunately, the new measures did not replace all the previous ones, they just added another system.

Akbar system of units was based on barley corn (Jau) for both weigth and length. It was widely used in India until adoption of the metric system in 1958. The weight units were slightly altered in 1833 to align with the British system. Here we provide conversion for the units after this change.

Does really exist since 1996? In fact it's even older. We launched the first version of our online units converter in 1995. There was no JavaScript there and all conversions had to be done on server. The service was slow. A year later the technology allowed us to create an instant units conversion service that became the prototype of what you see now.
