<p>[QUOTE=&quot;-jeffB, post: 2374953, member: 27832&quot;]Your arithmetic is correct, but I think assuming only 5% accuracy for even these cheap scales is pretty harsh. I would expect absolute accuracy as shipped to be closer to 1% in the general case, and the scales can be user-calibrated to improve that greatly.</p><p><br /></p><p><i>Repeatability</i> is the more important issue. If I weigh the same coin many times, how much does the weight vary? In my experience, even the cheap scales do a pretty good job at this. This means that if you have a known good coin to compare to, you can establish with very high confidence whether an unknown coin is likely to be within tolerance.</p><p><br /></p><p>If I get some time, I&#039;ll run some experiments on my scale and post the results over on <a href="https://www.cointalk.com/threads/need-a-digital-scale-for-coins-and-other-light-weight-objects.180600/" class="internalLink ProxyLink" data-proxy-href="https://www.cointalk.com/threads/need-a-digital-scale-for-coins-and-other-light-weight-objects.180600/">the scales thread where we&#039;ve been discussing this</a>.[/QUOTE]</p><p><br /></p>
