I am currently reading through everything before I start building and noticed the grams confusion.
28g = 1oz as 16oz = 1lb.
The 31g = 1oz in other circles. Gold/precious metals is the only area I'm area of from experience but I haven't researched for any others. So if you have an ounce of gold you actually have 31g. but an ounce of airplane is 28g.
Why that is, I have no idea.
Now you got me to thinking..........and that could be dangerous!!!!! I have always used 28.35g = 1oz and I always thought it made no difference
if one was weighing feathers or lead. I'm going to do a little more checking and let you know.
