Please convert 5.5kg/m cube to g/cm cube

We know that $1 \text{ kg} = 1000 \text{ g}$.
So, we multiply the given value by the conversion factor $\frac{1000 \text{ g}}{1 \text{ kg}}$.

$$5.5 \frac{\text{kg}}{\text{m}^3} \times \frac{1000 \text{ g}}{1 \text{ kg}} = 5500 \frac{\text{g}}{\text{m}^3}$$

We know that $1 \text{ m} = 100 \text{ cm}$.
Therefore, $1 \text{ m}^3 = (100 \text{ cm})^3 = 100^3 \text{ cm}^3 = 1,000,000 \text{ cm}^3$.
So, we multiply the current value by the conversion factor $\frac{1 \text{ m}^3}{1,000,000 \text{ cm}^3}$.

$$5500 \frac{\text{g}}{\text{m}^3} \times \frac{1 \text{ m}^3}{1,000,000 \text{ cm}^3}$$

$$\frac{5500}{1,000,000} \frac{\text{g}}{\text{cm}^3} = 0.0055 \frac{\text{g}}{\text{cm}^3}$$

The converted value is $0.0055 \frac{\text{g}}{\text{cm}^3}$.
