To convert meters to kilometers, you divide by 1,000, since there are 1,000 meters in a kilometer.
Given: \[ 3.875 \times 10^9 \text{ meters} \]
Now, we convert to kilometers: \[ \frac{3.875 \times 10^9 \text{ meters}}{1,000} = 3.875 \times 10^9 \div 10^3 = 3.875 \times 10^{9-3} = 3.875 \times 10^6 \text{ kilometers} \]
Thus, \(3.875 \times 10^9\) meters is equal to \(3.875 \times 10^6\) kilometers.
The final answer is: \[ 3.875 \times 10^6 \text{ kilometers} \]
