Conversion derivation

Express both acre and cm² in the same base unit m² (square meter), then cancel the shared base unit.

1
Rewrite acre in the base unit
$1 acre = 4, 046.86 m^{2}$
2
Rewrite cm² in the base unit
$1 c m^{2} = 0.0001 m^{2}$
3
Forward conversion
$1 acre = \frac{4 , 046.86 m ^{2}}{0.0001 m ^{2}} \times 1 c m^{2} = \frac{4 , 046.86}{0.0001} c m^{2} = 40, 468, 600 c m^{2}$
4
Reverse conversion
$1 c m^{2} = \frac{0.0001 m ^{2}}{4 , 046.86 m ^{2}} \times 1 acre = \frac{0.0001}{4 , 046.86} acre = 2.47105163 \times 1 0^{- 8} acre$
