The problem asks to convert 500 milligrams (mg) to hectograms (hg).

1. Problem Description

The problem asks to convert 500 milligrams (mg) to hectograms (hg).

2. Solution Steps

First, let's establish the conversion factors between milligrams, grams, and hectograms.

1 gram (g) = 1000 milligrams (mg)

1 hectogram (hg) = 100 grams (g)

We are given 500 mg and need to convert this to hg.

Step 1: Convert milligrams to grams.

$grams = \frac{milligrams}{1000}$

$grams = \frac{500 mg}{1000} = 0.5 g$

Step 2: Convert grams to hectograms.

$hectograms = \frac{grams}{100}$

$hectograms = \frac{0.5 g}{100} = 0.005 hg$

3. Final Answer

0. 005 hg
