Square Centimeters to Square Feet (cm² to ft²)
1 square centimeter equals 0.001076391042 square feet (rounded).
How to convert square centimeters to square feet
To convert square centimeters to square feet, multiply the number of square centimeters by 0.001076391042. The factor is rounded to 10 significant digits. To go the other way, multiply square feet by 929.0304.
square feet = square centimeters × 0.001076391042
Example: 10 square centimeters = 0.01076391042 square feet.
About these units
Square Centimeter (cm²)
A square one centimeter on a side; 1/10,000 of a square meter.
Physicists, rather than surveyors, put the centimeter at the center of a measuring system. Carl Friedrich Gauss proposed absolute units based on length, mass and time in 1832, choosing the millimeter, and in 1873 a British Association committee including James Clerk Maxwell and William Thomson (Lord Kelvin) recommended the centimeter, gram and second instead. In that CGS system the square centimeter turns up inside derived units, such as the stokes of kinematic viscosity, defined as one square centimeter per second.
A square centimeter is one ten-thousandth of a square meter, so 10,000 of them fill a square meter. It is a natural size for small flat things: a square inch is exactly 6.4516 cm², and a square foot is exactly 929.0304 cm². Because the CGS system defined force and pressure with the centimeter, the dyne per square centimeter became its unit of pressure, called the barye, which equals 0.1 pascal. SI practice prefers the square meter for large areas and the square millimeter for very small ones.
1 square centimeter = 0.0001 square meters (exactly).

Square Foot (ft²)
Exactly 0.09290304 m². The standard unit for floor areas and real estate in the US, UK and India.
Feet came first, and they were not all the same length. As a body-based unit, the foot ranged historically between about 250 and 335 millimeters, with ancient Greek and Roman feet near 300 mm. In medieval England a statute foot was set at 10/11 of an older Belgic foot, and Charlemagne's attempt around 790 to standardize units largely failed. The square foot is simply that length squared, so its size changed along with the foot.
The 1959 international agreement fixed the foot at exactly 0.3048 meter, so one square foot is exactly 0.09290304 m², or 144 square inches. The United Kingdom adopted the new foot in 1964. Today the square foot is the usual way of listing property in the United States, Canada, the United Kingdom, India, Pakistan, Singapore and Hong Kong, although the measuring convention varies: agents may measure corner to corner, subtract unheated space, or add heated space that extends beyond the end-to-end measurement. The world's smallest park has been reported at 2.6 sq ft.
1 square foot = 0.09290304 square meters (exactly).
