813 cg
8130 cg
81.3 cg

Explanation:

Step1: Consider real - life amounts

A pain - relief pill is very small, so 500 kilograms and 500 grams are far too large. Milligrams are a more appropriate unit for the amount of active ingredient in a pill.

Step2: Use conversion factor

1 gram = 100 centigrams. To convert 0.813 grams to centigrams, multiply by 100. So, $0.813\times100 = 81.3$ centigrams.

Answer:

1. 500 milligrams
2. 81.3 cg
