Decimal and binary are different
KB, MB and GB use powers of 1,000. KiB, MiB and GiB use powers of 1,024. Keeping the symbols distinct prevents common storage errors.
Storage and network speed use different units
File sizes are commonly shown in bytes, while internet speeds are usually bits per second. The transfer planner performs the eight-bit conversion automatically.
Data storage converter FAQ
Is 1 GB equal to 1,000 MB or 1,024 MB?
1 GB equals 1,000 MB. The binary relationship is 1 GiB equals 1,024 MiB.
Why does a 1 TB drive show about 931 GiB?
The manufacturer uses 1,000,000,000,000 bytes, while a GiB contains 1,073,741,824 bytes.
Are file-count and transfer-time results exact?
No. File sizes, protocol overhead, device formatting and real connection speed vary, so planning results are estimates.
