Coins don't all weigh the same, for instance a nickel will weigh something like between 4.8 and 5.2 (or something around there).
If you need a cheap scale that is accurate as fuck for a long time, I got mine bout a year ago and it is still calibrated amazing http://www.amazon.com/gp/aw/d/B00AN44MJI/ref=aw_d_img_back_arts-crafts?qid=1357184959&sr=8-17 I have had mine for about a year and my brother just bought one like a week so cuz he liked it so much, it even has the respect to say hello and goodbye when you turn it on/off haha, some do some dont though. But shit it comes delivered for like 17 bucks Sent from woah sweet Grasscity Forum
Is this true area 11,i just got a scale same problem so 10 grams should weigh 12.5 on the scale. Am I right?
it certainly can, but probably not nearly enough for that sort of scale op has to detect. you can see it on a gemini-20 (a commonly used consumer scale for mg weights) on a good day
