[Nfb-science] Accessible scale in grain units

[John Gardner]

Well as any fool knows a grain is 1/7000 of a pound. In case more detail is needed, there are 20 grains in a scruple, 3 scruples in a dram, 8 drams per ounce, and 12 ounces per pound. That is avoirdupois ounce and pound by the way, not to be confused with troy ounces, etc. 

By the way I must not be a fool, because I didn't know this. I looked it up. Wonder why scientists use metric system.

John
