1 acre is 43,560 sq ft, which is 4,046.8564224 m². A 1,200 sq ft flat is about 111.5 m² (1,200 × 0.09290304). Convert the area as a whole, or convert each side first and then multiply — do not mix linear feet with square metres in the same step.
Convert the number you already have. This is not GIS, a circle-rate lookup, or a surveyor’s closure. Carpet versus built-up still needs the loading the builder published — converting units does not change that loading.
It is not a survey, a GIS measurement, or a circle-rate lookup — plot-shape irregularities and carpet-versus-built-up loading sit outside a unit swap.
Static conversion factors — not for precision metrology.
43,560 sq ft. That figure is exact in the international foot this converter uses.
Instruments apply temperature, calibration, and rounding rules this converter does not. For everyday conversions the factors here are exact; for certification, use calibrated equipment.
Where both exist — such as gallons — the unit list names each, so pick the one you mean.
