Given:

Mass, m=4.79×105 kg

Calculation:

The given mass is m=4.79×105 kg

First, we need to remove the “kilo” from the given mass

m=4.79×105×103 g=4.79×108 g

We know that the 108 lies between “Mega” and “Giga”, therefore we can use these prefix, however our question demands for a value which is greater than 1 and lesser than 1000, if we use “Giga” prefix the value will come as

m=4.79×108109 Gg=0.479 Gg<1

Therefore we have to use “Mega” prefix so that value will between 1 and 1000, the restate value is

m=4.79×108106 Mg=479 Mg

Thus, the restate value of the number is 479 Mg.

Conclusion:

Restating a number using metric prefix, can convert any value to be fit between 1 and 1000 which is convenient for scientific and engineering calculation.
