ConverterData Storage Converter
Convert bits, bytes, and storage prefixes with Decimal SI labels or explicitly selected IEC Binary units.
Decimal kB, MB, GB, and TB use powers of 1000. Binary mode uses KiB, MiB, GiB, and TiB with powers of 1024, backed by bounded exact rational arithmetic.
What Convention Does The Source Use?
Choose Decimal SI for labels such as kB, MB, GB, and TB. Choose IEC Binary only when the intended units are KiB, MiB, GiB, or TiB. The tools change labels and factors together.
Check uppercase B for bytes and lowercase b or the word bit for bits. A storage quantity is not the same as a transfer rate such as Mbps.
What This Category Covers
- Bits, bytes, kB, MB, GB, and TB quantities
- Decimal SI powers of 1000 and IEC Binary powers of 1024
- MB versus MiB and GB versus GiB labels
- Raw-byte precision and fractional-byte interpretation
- Storage quantities versus internet-speed notation
Common Use Cases
- Use Decimal SI by default for unqualified kB, MB, GB, and TB labels.
- Switch to IEC Binary when the source explicitly uses KiB, MiB, GiB, or TiB.
- Separate byte quantities from bit quantities and per-second network rates.
Quick Reference
| Task | Recommended Tool | Why It Helps |
|---|---|---|
| Decimal or binary prefix change | MB to GB | Converts MB to GB by 1000 or MiB to GiB by 1024 with matching labels. |
| Raw byte interpretation | Bytes to GB | Retains large byte counts with bounded exact arithmetic. |
| Bit and byte quantities | Bits to Bytes | Uses the exact relationship 8 bit = 1 B and flags fractional-byte interpretation. |
| Capacity display comparison | TB to GB | Expresses a stated quantity but does not predict usable or billable space. |
Decimal SI And IEC Binary Are Different Conventions
Unqualified decimal labels use powers of 1000 here: 1 kB is 1000 B, 1 MB is 1000 kB, and 1 GB is 1000 MB. IEC Binary uses powers of 1024 with distinct labels: KiB, MiB, GiB, and TiB.
A converter result does not determine usable disk space, filesystem overhead, provider billing, upload acceptance, compression, redundancy, or transfer duration. Keep the source byte count and convention when those decisions matter.

Data Storage Converter FAQ
Use Decimal SI for kB, MB, GB, and TB labels. Each adjacent prefix step uses a factor of 1000.
Use IEC Binary when the source or destination means KiB, MiB, GiB, or TiB. Each adjacent prefix step uses a factor of 1024.
No. One byte equals exactly eight bits. A bit or byte quantity is also different from a per-second transfer rate.
Not necessarily. Filesystems, reserved areas, redundancy, compression, and provider rules are outside a unit conversion.
