Quick way to test a scales accuracy.

I've been think about this for a while.. How do I know my scale is accurate? How do I know my dealer's scale is accurate? These can be tough questions. It's really impossible to know unless you weigh something that has a known weight value such as a calibration weight. Well what do we know the weight of? There's not much. I searched my apartment for quite a while trying to find something I knew the weight of. Well I finaly figured it out.

A US QUARTER!!!!! I can look up the weight of a quarter, because their construction is very regulated and duplicated over an over again.. plus.. there are machines that can count change just by weighing the coins, so the weight must be very specific for each quarter!! Why didn't I think of this before???

Ok so down to business. here's a list of US Currency weight.

Penny - 2.5grams

Nickel - 5.0grams

Dime - 2.268grams (This will show up as 2.3grams on a scale with only 10th of a gram sensitivity.)

Quarter - 5.67grams (This will show up as 5.7grams on a scale with only 10th of a gram sensitivity.)

I'm writing these weights on my scale with a sharpie so I don't forget.
I imagine it'd be ok if the scale was off by .1 grams, but anything more than that and I'd start to wonder how far off it would be at higher weights.

I think this is a great piece of knowledge because now you can test yours and other scales integrity by using something we all have a lot of----> Pocket Change!!!!

It would also be a really reasuring thing to show your clientel if you're a dealer. kind of a way to show people that you're not shorting them. If they say it looks skimpy you can weigh it, then if they question your scale you can put a quarter on and show them. If they don't believe you about the weight of the quarter have them look it up on the web.

Happy smoking everyone!!!!! :stoned:

I'm gonna pack a celebratory bowl. :stoned:

yea i use paper money too 1.0

I've always used pennies. One of these days I'll get a tripple beam balance because I also do a lot of experimental chemistry.

1 gram dubs
paper money = 1.0

very good fellow stoners
you know your shit

i always used a nickle because its easier to tell on a hand scale.

yeah, but if you buy a sack you should always weigh out of bag, or if u dont want residue on ur scale, just rip off the zip part of the bag because it ways alot.... my freind bought an ounce, and he weiged it in bag, and the bag was a big hefty with a easy zip lock, and the bag weighed 3.6.... and the ounce weighed out to 28.4 in bag

nickel is .5 not 5.0grams

no its 5 grams

Yep.

or a nickel, a nickel ways 5 grams i believe, but i have a digital scale with the 100gram weight to calibrate it if it messes up anyway.
