Leonard,

With reference to your question of July 27th as to
whether the avdp. stone of 14 avdp.lb. has ever been
12 avdp.lb. or 16 avdp.lb. The answer is no, as shown
below:

1 troy st. = 14 troy lb.
1 avdp.gal. = 8 avdp.lb.
1 avdp.st. = 14 avdp.lb.
1 avdp. peck = 16 avdp.lb.
1 long st. = 14 long lb.
1 merc.st. = 14 merc.lb.
1 tron st. = 14 tron lb.

The following weights are required as shown below:

175 troy st. = 1 troy ton
200 troy st. = 1 merc. ton
400 troy st. = 1 merc. last
252 avdp.gal. = 1 troy ton
288 avdp.gal. = 1 merc. ton
576 avdp.gal. = 1 merc. last
144 avdp.st. = 1 troy ton
xxxxxxxxxxxx = 1 merc. ton
xxxxxxxxxxxx = 1 merc. last
126 avdp. peck = 1 troy ton
144 avdp. peck = 1 merc. ton
288 avdp. peck = 1 merc. last
63 avdp. bucket = 1 troy ton
72 avdp. bucket = 1 merc. ton
144 avdp. bucket = 1 merc. last
18 avdp.cwt. = 1 troy ton
xxxxxxxxxxxx = 1 merc. ton
xxxxxxxxxxxx = 1 merc. last
140 long st. = 1 troy ton
160 long st. = 1 merc. ton
320 long st. = 1 merc. last
35 long frail = 1 troy ton
40 long frail = 1 merc. ton
80 long frail = 1 merc. last
xxxxxxxxxxxx = 1 troy ton
150 merc.st. = 1 merc. ton
300 merc.st. = 1 merc. last
xxxxxxxxxxxx = 1 troy ton
30 fotmals = 1 merc. ton
60 fotmals = 1 merc. last
105 tron st. = 1 troy ton
120 tron st. = 1 merc. ton
240 tron st. = 1 merc. last
70 tron scorewt. = 1 troy ton
80 tron scorewt. = 1 merc. ton
160 tron scorewt. = 1 merc. last

There has never been 12 pounds of anything in any
weights & measures system.

P.S.
Leonard, I've put the answer on this bulletin board as
the B.W.M.A. did not want any more discussion on the
"Questions to B.W.M.A." bulletin board.

xcole,

what do the years on your pages mean ? ("why the metric system is based on a lie" thread)
I dont't want to bitching, but I don't see the point of starting a new thread without even replying to others you started.
