Converting square meters to square feet needs the squared factor: 1 m is 3.281 ft, so 1 m² is 3.281² ≈ 10.76 sq ft. Using 3.28 directly turns a 100 m² apartment into '328 sq ft' instead of the correct ~1,076 sq ft.
For areas the length factor must be squared, using it directly is the classic trap. 1 km is 1,000 m, but 1 km² is 1,000,000 m², and 1 m² is 10,000 cm². The rule: convert the length unit, then square the factor.
