Grade 5 Measurement Worksheet: Converting Metric Units of Weight (kg to g and g to kg)

Problem Overview:

The task involves converting between metric units of weight, specifically kilograms (kg) and grams (g). The key conversion factor is:

$$
1 \text{ kilogram (kg)} = 1,000 \text{ grams (g)}
$$

This means:
- To convert from kilograms to grams, multiply by 1,000.
- To convert from grams to kilograms, divide by 1,000.

Solution:

We will solve each problem step by step using the conversion factor.
