Precision changes displayed rounding, not calculation accuracy.
ac = km² × 247.105381467165ac = km² × 247.105381467165
Multiply the km² reading by 247.105381467165.
1 km² ≈ 247.1053815 ac
1 × 247.105381467165 ≈ 247.1053815
100 km² ≈ 24710.53815 ac
100 × 247.105381467165 ≈ 24710.53815
Area factors scale with the square of the length factor. For example, 1 ft = 0.3048 m gives 1 ft² = 0.3048² m² = 0.09290304 m².
