Multiply kg by 1000 to get g
Multiply m^3 by (100)^3 to get cm^3

So: 1000/(100^3) = 1/1000

998.2 kg/m^3 = 0.9982 g/cm^3

(998.2 kg/m^3) (1000 g/1 kg) (1 m^3/10^6 cm^3) = 0.9982 g/cm^3. The units cancel same way as the numbers.

As for the 10^6, 1 m = 10^2 cm and take the 3d power.

1 kg = 1000 grams
1m^3 = 1,000,000 cm^3
998.2 kg/m^3 = 998.2 X1000g/kg/1,000,000 cm^3/m^3
= 998.2X10^3/10^6 = 998. X10-3= .9982 grams/cm^3

998.2 kg/m^3 =
998.2*(1000)/(100)^3 g/cm^3(since 1 kg = 1000 and 1 m = 100 cm)
9982*10^2/10^6 =
9982*10^-(4) = 0.9982 g/cm^3

1 m^3 = 1,000,000 cm^3
1kg = 1000 g

That means
998.2 kg/m^3 / 1,000,000 cm^3/m^3 = 0.0009982 kg/cm^3 = 0.9982 g/cm^3
