"It's been a long time since high school I guess. The conversion chart I just looked at says, 1 gram is .035273 of an ounce... If a shot glass is an ounce, a gram isn't a heck of a lot of material. So the multigram order could fit in a thimble."
grajekk,
FYI, the conversion you referred to is between units of MASS. A shot glass is indeed 1 ounce, but it is a fluid ounce, which is a unit of VOLUME. You cannot compare the two directly as you have.
