Answer
$$1.8 \space g$$
Work Step by Step
1. According to the Table 2.7 (Page 38), the equality between $g$ and $kg$ is:
$$ 1 \space kg =1000 \space g$$
- Therefore, the conversion factors are:
$$\frac{1 \space kg}{1000 \space g} \space and \space \frac{1000 \space g}{1 \space kg}$$
2. Choose the conversion factor that will convert the mass into grams:
$$0.0018 \space kg \times \frac{1000 \space g}{1 \space kg} = 1.8 \space g$$
