The measurement of 3.000 000 g is the most precise.


The precision of a single measurement refers to the position of the rightmost significant digit.

If the position is to the right of the decimal point, we state the precision as "so many decimal places".

Thus, a measurement of 3.000 000 g has a precision of six decimal places.

The other measurements have precisions of only four or five decimal places.
