Bytes to gigabytes – convert B to GB
Convert bytes to gigabytes (B to GB) to understand file sizes, disk capacity, cloud storage and mobile data in friendlier units. This page uses decimal gigabytes (1 GB = 1,000,000,000 bytes).
Open the interactive B → GB converter:
Use main converter (B → GB) or switch to GB → BThe data converter also supports KB, MB, GB and TB using decimal (10-based) units, which is what most storage devices and ISPs quote.
Quick reference: bytes to gigabytes
One gigabyte is 1,000,000,000 bytes. So: GB = bytes ÷ 1,000,000,000. Examples:
| Bytes (B) | Gigabytes (GB, decimal) |
|---|---|
| 1,000,000 B | 0.001 GB |
| 10,000,000 B | 0.01 GB |
| 100,000,000 B | 0.1 GB |
| 500,000,000 B | 0.5 GB |
| 1,000,000,000 B | 1 GB |
| 5,000,000,000 B | 5 GB |
Why convert bytes to gigabytes?
B to GB is handy when you:
- Translate raw byte counts into gigabytes for reports or dashboards.
- Check how much space large datasets or backups will need.
- Compare application logs or database sizes to storage quotas.
- Explain the difference between bytes, KB, MB and GB to non-technical users.
