To convert \(8.0724 \times 10^{-12}\) centimeters to kilometers, we use the conversion factor that \(1\) kilometer is equal to \(100,000\) centimeters or \(1 \text{ km} = 10^5 \text{ cm}\).

We start with the given measurement in centimeters:

\[ 8.0724 \times 10^{-12} \text{ cm} \]

To convert centimeters to kilometers, we divide the number of centimeters by \(100,000\) or \(10^5\):

\[ 8.0724 \times 10^{-12} \text{ cm} \times \frac{1 \text{ km}}{10^5 \text{ cm}} = \frac{8.0724 \times 10^{-12}}{10^5} \text{ km} \]

This simplifies to:

\[ 8.0724 \times 10^{-12 - 5} \text{ km} = 8.0724 \times 10^{-17} \text{ km} \]

Thus, the answer is:

\[ \boxed{8.0724 \times 10^{-17}} \text{ kilometers} \]
