2.7870912 km2
Answer: 510,000,000 km² = 5.489e+15 ft²
5,000,000 sq ft = 0.464515 sq km
13 square kilometers is 139,930,000 square feet.
about 30.2 million km square
2.65x1014Or for a more specific answer 263,450,880,000,000. the way I found this out was by multiplying how many square feet are in a square mile (27,878,400) and by how many square miles are in north america (9,450,000)
It is about 2,381,741 square kilometres or 919,595 square miles.
1 square km = 1 million square metres.
China has a total land area of approximately 9.6 million square kilometers, which is equivalent to 9.6 trillion square meters.
The conversion factor is: 0.00000009292,500 square feet x 0.0000000929 = 0.00023225 square km
The surface area of the Earth is: 4 * pi * r^2 = 4 * pi * (6378.1 km)^2 = 511201962.3 square km And, since there are 3280.839895 feet per km, there are 10763910.42 square feet per square km. So, the square footage of the earth (assuming a spherical shape, not ellipsoidal) is: 511201962.3 * 10763910.42 = 5.502532127 x 10^15 square feet That's approximately: 5,502,532,127,000,000 square feet Which is read, "Five quadrillion, five hundred two trillion, five hundred thirty-two billion, one hundred twenty-seven million square feet".
India's area is 3.287 million km²
"1 km" is a distance. It has no area.1 square km = 10,763,910 square feet (rounded)
