THE MATH
Convert to a base unit, then to the target:
result = value × (from factor ÷ to factor)
result = value × (from factor ÷ to factor)
Area is length squared, so each conversion factor is the square of the matching length factor.
Common land units: an acre is 43,560 sq ft; a hectare is 10,000 sq m (about 2.47 acres).
Common land units: an acre is 43,560 sq ft; a hectare is 10,000 sq m (about 2.47 acres).
Because area goes as length squared, doubling a length quadruples the area.
Acres and hectares are the usual land-area units; a hectare is roughly two and a half acres.
Keep units consistent: sq ft for rooms, acres or hectares for land.
