Are you trying to drive me crazy ? :biggrin:
Earth Mass
5.9736×10[24] kg[3]
In a square meter, there are 100cm X 100cm = 1,000 sq cm / square meter.
In a kilometer, there are 1,000m X 1,000m = 1,000,000 sq meters. So, 1,000,000 X 1,000 = 1,000,000,000 sq cm in a square kilometer. (that's 1 billion).
1kg / cm^2, this means there's 1 *billion* kg / km^2.
1 square centimeter = 1.0 × 10[14]square nanometer .
I give up , you finish it.:biggrin:
Why does Zet like driving me crazy?
