148939063.133 km² divided by 6800000000000?
Earth's total land mass divided by Earth's total human population (6.8trillion).
meters squared, kilometers squared.
also measurements in acres please.
thanks.
What I really want to find out, is to try and present this easy mathematical calculation against this difficult topic of 'over-population'...
Whatever the answer may be, it should attract a tactful array of responses.

Population density = population / area
The worldwide human population density is 6.8 billion ÷ 510 million = 13.3p per km² (34.5 per sq. mile).
If only the Earth's land area of 150 million km² (58 million sq. miles) is taken into account, then human population density increases to 45.3p per km² (117.2 per sq. mile). This calculation includes all continental and island land area, including Antarctica.
If Antarctica is also excluded, then population density rises to 50 people per km² (129.28 per sq. mile)
