Multiply the square foot figure by 0.000009290304. So ha = ft² × 0.000009290304. For a quick mental estimate, dividing by about 107639.1 gets you close enough for most everyday purposes.

Yes. Since the 1959 international yard and pound agreement, the imperial and metric systems are related by exact definitions rather than measurements — the inch is exactly 25.4 mm and the pound exactly 0.45359237 kg. Everything derived from those, including this conversion, is therefore exact. Round at the end rather than partway through, since rounding ft² before converting introduces an error the conversion then multiplies.
