How many pieces in a pound? (estimation...)

Good Afternoon,
I'm looking to estimate the number of pieces in my collection.  I have an
average mix of bricks and specialty pieces, That have come from sets, but also
from garage sale aquisitions, PAB, and friends donations.  I don't have the time
to count them, and since they are not limited to sets (as if I could remember
all the sets I baught over the last 22 years) I can't count them that way.

Anyone have a (very general) estimate as to how many lego pieces are in a pound?

Thanks,
Karl

The estimations I've heard and used (to reasonable accuracy) are 400/pound and
500/pound. So I generally go with 450/pound and it seems to work out ok. I've
also heard the estimation 1000/kg, which works out to roughly 454/pound, which
is again in the same ballpark.

Thanks DaveE,

After I get the weight of one of my dollar store microwave containers (my
preferred means of storage) from the delicate mail shipping scale here at work,
I am going to try this out.

Much Appreciated,
Karl

For the curious, I'm actually in the middle of doing a more precise calculation.
After I answered yesterday, I went around and looked for previous LUGNET posts
on the matter, and found a staggering number of estimations for less pieces per
pound than I had suggested. Specifically, I found references to:

300 per 1 pound
1000 per 3 pounds
1000 per 1 kg
200 per 1 pound
300 per 1 pound (again)
350 per 1 pound

In light of that, I'm currently trying to gather data from BrickLink, which
happens to have weight information for some pieces! Following this, I'm hoping
to create a cross-reference with set inventories and see how much specific sets
weigh in terms of pure brick. Given that less than half of the parts on record
seem to have weight information, this may not yield good data, but hopefully
it'll be more accurate than rough guessing.

So, for starters, I checked the weight of my entire collection according to
Peeron:

Total Weight: 446376.280000005 grams
Total Pieces: 367662
Total with weight: 10426
Total without weight: 2541
Total pieces with weight: 339630
Total pieces without weight: 28032

So, of the 12967 different types of elements I own, BrickLink had data for
roughly 10426 of them. Some are inaccurate, like combination parts (minifig
legs, etc), but it should be roughly close.

Of my total 367662 pieces total, it found weights for about 92% of them
(339630). The total weight it found was about 984.091245 pounds, which boils
down to about 345.12 pieces per pound, or 760.86 per kilogram.

So, pending further investigation, it looks like 350/pound should be a good
estimate!

BrickLink also has info (in many cases) for the weight of: the complete set, the
original box, and the instructions, from which you could calculate the weight of
just the parts (and polybags).

Newer sets are more likely to have more complete info- it's only been recently
that weight info was useful on BL, it used to just be collected for amusement.

OK Dave, you have me scared now.  Accoring to Peeron, I have 335367 parts from
sets.  Add several hundred pounds of Pick-A-Brick and I seem to be in the
half-ton ballpark as well.  That number just sounds huge.

Or it means I am half way there.  Periodically someone new walks into my
basement and says "Wow!  That is a TON of LEGO!"
