About converting Square Feet to Square Kilometers

Square Feet (ft²) and Square Kilometers (km²) are both units of area, so converting between them is a single multiplication: multiply your Square Feet figure by 0.0000000929. Ten Square Feet comes to 0.000000929 Square Kilometers, and a hundred works out at 0.00000929 Square Kilometers.

Rule of thumb: going from Square Feet to Square Kilometers divides, so the figure always shrinks — it takes about 10,763,910.42 Square Feet to make a single Square Kilometer. If your answer came out bigger, you have the conversion the wrong way round.

What is a Square Foot?

The square foot is the area of a square one foot on a side, and it is the unit American and Indian real estate runs on — apartments, offices and warehouses are advertised, valued and rented by it, while most of Europe quotes the identical thing in square meters. It is also where the commonest conceptual mistake about area surfaces. Area scales with the square of length, so converting a room’s dimensions and converting its floor area are not the same operation: double a room’s length and width and you have not doubled the floor, you have quadrupled it.

What is a Square Kilometer?

A square kilometer is the area of a square one kilometer on a side, and it is how the world reports anything from the size of a town upward: city footprints, lakes, national parks, forest lost to fire, the areas of countries. Its classic trap is that the prefix is squared along with the unit — both sides of the square grow by a thousand, so the area grows by that factor twice over, and people who expect a simple thousand-fold jump land three orders of magnitude out. The same squaring is why a map at twice the scale covers four times the ground.

To put both in perspective: a typical US one-bedroom apartment is around 700 square feet, while Central Park in New York is about 3.4 square kilometers.
