<p>[QUOTE="desertgem, post: 1444750, member: 15199"]The one you mention above doesn't indicate it can do oz or troy ounces. True that you can convert grams into both with a calculator or your brain, but often a time saver. I have one similar to this, but different manufacturer name. It also indicates that it has a resolution of .01gram rather than .1 gram ( that is the 300 x.1gram of the one you indicated). That is useful in the tolerances are generally in the ,01gram range. For example most people just say that a common wheat cent ( not steel) weighs 3.11 grams, but it has a tolerance of +/- 0.13grams, so they can be real and weigh from 2.98 grams to 3.24 grams, but generally very close to 3.11 grams unc.</p><p><br /></p><p><a href="http://www.wizardcoinsupply.com/professional-digital-table-top-scale-500-x-.01-g.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.wizardcoinsupply.com/professional-digital-table-top-scale-500-x-.01-g.html" rel="nofollow"><br /></a></p><p><a href="http://www.wizardcoinsupply.com/professional-digital-table-top-scale-500-x-.01-g.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.wizardcoinsupply.com/professional-digital-table-top-scale-500-x-.01-g.html" rel="nofollow">http://www.wizardcoinsupply.com/professional-digital-table-top-scale-500-x-.01-g.html</a></p><p><br /></p><p>If you are near a harbor freight store or catalog, I would also recommend a digital caliper.
