daniel added a comment. @DSGalaktos not for "some reason", but because it's the scientific standard to not assume absolute accuracy per default.
From https://en.wikipedia.org/wiki/False_precision: "In science and engineering, convention dictates that unless a margin of error is explicitly stated, the number of significant figures used in the presentation of data should be limited to what is warranted by the precision of those data." And from https://en.wikipedia.org/wiki/Significance_arithmetic: " If a calculation is done without analysis of the uncertainty involved, a result that is written with too many significant figures can be taken to imply a higher precision than is known, and a result that is written with too few significant figures results in an avoidable loss of precision". If we want to be able to do any arithmetics with the Quantities (like unit conversion), we should not assume absolute certainty per default, since it would introduce "false precision".
