Laurie pointed out the precision factors for the weighing scale and I also briefly thought --- is that the conversion? But it is not the conversion factor. The number of grams and tenths of ounces of precision are merely the lowest potential value that can be measured with any degree of precision (not accuracy since this requires calibration). If you use the scale a lot you will notice that it jumps by a factor of 2 for grams and a factor of 1 for tenths of ounces. If you measure an object that weighs 0.1 oz, it will hover for a while and settle on either 2 g or 4 g. If you start measuring heavier objects repeatedly, then you will start to see that the averages of these values will approximate the 35.2 g per ounce. If the scale had a precision rating of 1 g, you would probably get a value of 3 g. with a few 1 g and 4 g measurements.
