To convert square kilometers to acres, first convert square kilometers to square meters (1 km² = 1,000,000 m²), then divide by the square meter equivalent of an acre. $13.2 \times 10^{6} \, \text{km}^{2} \times 1,000,000 \, \text{m}^{2}/\text{km}^{2} = 13.2 \times 10^{12} \, \text{m}^{2}$. Dividing by 4047 m²/acre gives $13.2 \times 10^{12} \, \text{m}^{2} / 4047 \, \text{m}^{2}/\text{acre} \approx 3.26 \times 10^{9}$ acres.
