Units explained
Dram (avoirdupois)
The avoirdupois dram (dr) equals one-sixteenth of an ounce, about 1.77 grams.
From Greek 'drachma' through Latin 'dragma'.
Historically pharmacy; today occasional cooking and firearms (powder) use.
Defined as 1/256 of the avoirdupois pound.
Deuteron Mass
The deuteron mass is about 3.344E-27 kg.
The mass of the deuteron, the nucleus of deuterium (one proton and one neutron).
Nuclear physics and fusion-energy research.
Established with the discovery of deuterium by Harold Urey in 1931.
