Verified step by step guidance

1. Understand the relationship between grams and kilograms in the metric system. The kilogram (kg) is the base unit of mass in the International System of Units (SI), and the gram (g) is a derived unit.
2. Recall the conversion factor between grams and kilograms: 1 kilogram equals 1000 grams, which can be written as \$1 \, \text{kg} = 1000 \ \text{g}$.
3. To convert 1 gram to kilograms, set up the conversion using the factor: \$1 \ \text{g} \times \frac{1 \ \text{kg}}{1000 \ \text{g}}$.
4. Simplify the expression by canceling grams and dividing: \$1 \times \frac{1}{1000} = 0.001 \ \text{kg}$.
5. Compare this result to the given options to identify the correct metric equivalent of 1 gram.
