검증된 단계별 안내1
Identify the units involved: you need to convert kilograms (kg) to centigrams (cg).
Recall the relationship between kilograms and grams: 1 kg = 1000 g.
Recall the relationship between grams and centigrams: 1 g = 100 cg.
Convert 0.459 kg to grams by multiplying by 1000: \(0.459 \text{ kg} \times 1000 = 459 \text{ g}\).
Convert grams to centigrams by multiplying by 100: \(459 \text{ g} \times 100 = 45900 \text{ cg}\).
