Lesson Steps:

1 kg = 100000 cg
Multiply both sides by 16.

1 cup = 8 oz (US standards)
Multiply both sides by 8.3

(Note: Since the asker hasn't specified the standards
1 Cup [US] = 8 Ounces [Fluid, US]
1 Cup [US] = 8.326742 Ounces [Fluid, UK]
1 Cup [Metric] = 8.7988 Ounces [Fluid, UK])

1 dm = 0.0001 km
Multiply both sides by 8.3

Answer:

16 kg = 1600000 cg
8.3 cup = 66.4 oz
8.3 dm = 0.00083 km
