Units explained
Pennyweight
The pennyweight (dwt) equals one-twentieth of a troy ounce, 24 grains (about 1.555 g).
From the mass of a medieval English silver penny; symbol dwt from 'denarius weight'.
Jewelry making and precious-metal scrap valuation in the US.
Derived from the medieval English coinage system.
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.
