<p>[QUOTE="messydesk, post: 5266273, member: 1765"]Correct, but you have the terms reversed. Precision refers to the number of digits a scale can give you consistently. If I have a scale that can give me a weight of 1.425887 grams, and it gives the same measurement every time, it's precise to the microgram. It may only have an accuracy of +/- 0.01 grams, however, which makes all the precision past the second decimal place meaningless. You might also have a scale that gives you random numbers after 2 decimal places, but those first two are always correct. In this case, you have a scale that is not precise enough for its accuracy. Often, however, the term accuracy is used to refer to being both accurate and precise.[/QUOTE]</p><p><br /></p>
