How many square feet are in a square metre?

10.7639, because a metre is 3.28084 feet and area scales with the square. This is the conversion people most often do by doubling or tripling a linear factor, which is wrong by an order of magnitude.

Is an acre the same everywhere?

The international acre is 4,046.8564224 square metres exactly, defined from the international yard. The US survey acre differs in about the ninth significant figure, which matters for cadastral survey and for nothing else.

Area across metric, imperial and Indian land units. The Indian units are regional by nature and the page says which convention it uses rather than implying a national standard.

Also called: sqft to sqm, square feet to square metres.

Method and background

How this is calculated

Areas convert as the square of their length factors, so a square foot is 0.3048² square metres. The Indian units (gunta, cent, ground, bigha) genuinely vary by state; a bigha in Uttar Pradesh is not a bigha in West Bengal, which is why the label names the region.

result = value * factor_from / factor_to

k: Each unit's size in m2
