So your result can only have 3 significant digits too, only one more for rounding.

63,2e6 is your answer.

More digits are only pseudo precision without anly information.
I think every science calculator has the right answer.

This I learned in science class...but sort of forgot and got hung up on high precision calculators!

Thank you very much for reminding me!
