  [tex]\dfrac{1.44\times10^8\text{ ac$\cdot$ft}}{8.81913\times10^5\text{ km}^2}=\dfrac{(1.44\times10^8)(4.356\times10^4\text{ ft}^3)(0.3048\text{ m/ft})^3}{(8.81913\times10^5\text{ km}^2)(10^3\text{ m/km})^2}\\\\=\dfrac{1.44\times4.356\times0.3048^3\times10^{12}}{8.81913\times10^{11}}\text{ m}\approx0.2014\text{ m}[/tex]
