What these units are
Square kilometers (km²). A square kilometer is one million square meters. It is used for districts, national parks and country areas — and one square kilometer is exactly 100 hectares.
Square feet (ft²). A square foot is 0.09290304 square meters. It is the standard unit for floor area and property listings in the United States and the UK.
Every factor is an exact definition, so the only loss is display rounding. Land figures quoted in acres and hectares are usually rounded at the source.
Converting Square kilometers to Square feet in practice
Working in square kilometers
A square kilometer is the area of a square one kilometer on each side, exactly 1,000,000 square meters or 100 hectares. It is the usual metric unit for large areas.
City and district areas, national parks, reservoirs, islands and administrative regions are measured in square kilometers. Satellite imagery and land-cover studies report extents this way as well.
One square kilometer equals exactly 0.386102158542 square miles, from the exact mile definition. Since output is rounded, a large area converted into square miles and back can return with the last digit changed.
The mistake is forgetting that a square kilometer is a million square meters, so a figure in hectares must be divided by one hundred, not multiplied. Square kilometers also describe area, never distance.
Square kilometers are the usual large-area unit; hectares divide each one into a hundred parts and square miles are 2.59 square kilometers each. Using hectares for a district, or square kilometers for a plot, misplaces the scale by a factor of a hundred either way.
Reading the result in square feet
A square foot is the area of a square with sides one foot long, exactly 0.09290304 square meters. It is a unit of area and not a unit of length.
Floor area in property listings, apartment sizes, tiles, paint coverage and roofing are quoted in square feet in the United States and several other markets. Carpets and timber are sold this way too.
The conversion to square meters is exact because the foot is exactly 0.3048 meters and the square of that is 0.09290304. Results are printed rounded, so a square foot figure changed to square meters and back may lose a digit.
A frequent mistake is multiplying a length in feet by itself when only one dimension was measured, or converting a linear foot rate to a square foot rate directly. The two measure different things.
Square feet measure rooms and buildings, square meters do the same on metric plans, and acres measure land. A square meter is about 10.76 square feet, so a floor area quoted in the wrong unit is off by roughly a factor of ten.
Checking a square kilometers to square feet conversion
Area factors are the square of the corresponding length factors, so the numbers move much faster than a reader expects. A square meter contains 10,000 square centimeters, and a square kilometer a million square meters, not a thousand.
The units that share a name across systems are still different sizes: a square mile and a square kilometer differ by a factor of about 2.59, and an acre is a fixed area rather than a square with equal sides, so it does not convert like the length units it is named after.
Land is where the reciprocal matters most, because acres and hectares are both in use for the same plots. When a figure moves between them, check it against a shape you can picture — a hectare is a square 100 meters on each side — rather than against the number alone.
