Why is there a difference between gigabyte/second (SI def.) and gigabyte/second [GB/s]?

The difference arises because gigabyte (SI def.) uses decimal prefixes based on 10^9 bytes, while GB/s sometimes refers to binary-based units approximating 2^30 bytes, causing differing byte counts per gigabyte.

When should I use this conversion?

Use this converter to ensure consistent interpretation of data transfer rates across devices and systems that report speeds using decimal or binary gigabyte units.

Does this converter apply to all data units?

No, this converter specifically handles gigabyte per second units defined by SI decimal and common computing conventions without extending to other byte sizes or data rates.
