Units explained
Wey
The wey was an English bulk weight, here taken as 252 pounds (about 114.3 kg).
From Old English 'waege', a weighing or balance.
Obsolete English unit for wool, cheese, and salt.

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.
