What does gn in weight stand for?

Answer 1

The meaning of the abbreviation 'gn' in weight is "grain".

Metric:

Today, metric grain (gn) is equal to 50 MICROgrams (mg). It is used in the weighing of precious stones. More commonly it is used in the measuring of gun powder by ammunition manufacturers and by those who reload their own ammunition. There are 7000 grains in one pound of gunpowder.

if your reloading ammo you just blew your gun up :)

If you have encountered the gn abbreviation on modern scales, particularly quite accurate ones, it is most likely metric grains.

In Imperial/British/Standard:

The term dates back to the early British (aka Imperial) system of weights and measures where grain was used as the basis of all weights and was, therefore, the smallest of all weights in this system.

1 grain = 1/7,000 of a pound (lb). Yes, one seven thousandth! the abbreviation mg stands for milligrams The Greek letter μ is used to symbolize the abbreviation for the prefix micro-, standing for exponential multiplication factor 10-6. μg= micrograms
