What is the rounded off number,to the nearest gram,of 4.86932 kg

One kilogram is equivalent to 1000 grams.
So
4.86932 kg = 4.86932*1000 g = 4869.32 g
To round to the nearest gram, we draw a vertical line at the decimal point:
4869  32
if the first digit after the  bar is 5 or over, we add one to the number before the bar. Otherwise we do nothing.
Since the first digit after the bar is 3,(less than 5), we don't have to do anything.
Now we only have to write down the number before the  as the rounded weight of 4869 g.
