Answer is: 9530 cg is not the same as 0.953 kilograms.
1) 1 kg = 1000 g; one kilogram is equal 1000 grams.
m = 953 g.
m = 953 g ÷ 1000 g/kg.
m = 0.953 kg.
2) 1 kg = 10⁶ g; one kilogram is equal 1000000 milligrams.
m = 953000 mg.
m = 953000 mg ÷ 1000000 mg/kg.
m = 0.953 kg.
3) 1 kg = 10⁵ cg; one kilogram is equal 100000 centigrams.
m = 9530 cg.
m = 9530 cg ÷ 100000 cg/kg.
m = 0.0953 kg.
