Good point.

What this is is pilot error. If you are rounding to decimal places for ease of calculation and losing precision, that is your error. And don't get all significant digits on me. This is not the fault of metric vs sae.

If you have a stick 10 cm long and convert that to meters, it becomes 0.1 m, then you can round it down to 0 m.

One unit of measure can not be more accurate than another. If your scale has a different level of precision for one unit vs another. That is your scale, not the system of measurement.

did you just take a non-metric measurement and raise it to a base 10 power? Can't you create some base 6 scale or something? 16 oz to a pint, 2 pints to a quart, 4 quarts to a gallon, 6 gallons to a "splosh".

Now there are 53 1/3 million trillion sploshes of water on earth. Or 1260 exalitres

All of these are reasons I switched to metric.. Because I will be more accurate.. I didn't start this thread to convince other people to switch... I just wanted to know if there were any others doing the same thing...

My scale is stupid... I will round less in grams.. Both are reason enough for me to switch
