[edit] significant figures

It is erroneous to take "150 micrograms" and restate it as ".0000004 ounces", because the first figure is only stating a value to an accuracy of two significant figures. The second purports an accuracy of seven, or in other words, five orders of magnitude more accurate (see 'spurious accuracy' in the significant figures article). This is a common error made by people converting units. --Leperflesh 21:59, 19 February 2007 (UTC)
