To convert bytes ($b$) to gigabytes ($GB$), you use the following formula:

$1 \text{ GB} = 1,073,741,824 \text{ bytes} \quad (\text{based on binary system})$

Calculation:

$\text{Value in GB} = \frac{\text{Value in bytes}}{1,073,741,824}$

$\text{Value in GB} = \frac{9,000,000,000}{1,073,741,824} \approx 8.38 \text{ GB}$

Final Answer:

$9,000,000,000 \, b \approx 8.38 \, \text{GB}$

Tip:

Always check whether a problem uses binary (base-2) or decimal (base-10) definitions for units, as they differ!
