Verified step by step guidance

1. Identify the relationship between kilograms and milligrams. Recall that 1 kilogram (kg) equals 1,000 grams (g), and 1 gram equals 1,000 milligrams (mg).
2. Convert kilograms to grams by multiplying the given mass in kilograms by 1,000: \$5.6\ \text{kg} \times 1,000 = 5,600\ \text{g}$.
3. Convert grams to milligrams by multiplying the mass in grams by 1,000: \$5,600\ \text{g} \times 1,000 = 5,600,000\ \text{mg}$.
4. Combine the two conversion steps into one calculation: \$5.6\ \text{kg} \times 1,000 \times 1,000 = 5.6 \times 10^{6}\ \text{mg}$.
5. Compare the calculated value to the given options to identify the correct conversion.
