1. The problem is to convert 4 kilometers (km) to meters (m). 2. The formula to convert kilometers to meters is: $$\text{meters} = \text{kilometers} \times 1000$$ because 1 km equals 1000 m. 3. Applying the formula: $$4 \text{ km} \times 1000 = 4000 \text{ m}$$ 4. Therefore, 4 kilometers is equal to 4000 meters.
