What is a Dram and a Pras (India)?

The dram (or drachm) can refer to several units. In the context of common weight conversion (Avoirdupois system), it is a unit of mass equal to 1/16 of an ounce or 1/256 of a pound. This Avoirdupois dram is approximately 1.7718 grams.

The Pras is an extremely small traditional Indian unit of mass, representing a minute fraction sometimes referenced historically. One Pras is approximately equal to 0.0000027902 grams.
