Printable worksheet for converting units of mass, focusing on grams and kilograms.

Problem Overview:

The worksheet requires converting between grams (g) and kilograms (kg). The key conversion factor to remember is:

$$
1 \text{ kg} = 1000 \text{ g}
$$

This means:
- To convert grams to kilograms, divide by 1000.
- To convert kilograms to grams, multiply by 1000.
