Area conversion
All conversions use the exact definition of each unit expressed in square meters. The imperial factors are exact squares of the length definitions: 1 ft = 0.3048 m, so 1 ft² = 0.09290304 m² exactly. The area is first converted to m², then into the target unit: result = area × factor(from) ÷ factor(to). Example: 50 m² → 538.2 ft².
