Computer & Data hub
Data storage, binary, hex and developer utilities.
About computer & data conversions
Developer utilities cover binary data math: bytes, KB, MB, GB, TB plus their binary cousins KiB, MiB, GiB, TiB. We surface both the SI decimal (1 GB = 10⁹ B) and IEC binary (1 GiB = 2³⁰ B) conventions so you can audit storage marketing claims against actual disk capacity.

When you'll reach for these
Practical scenarios where this hub shines.
Capacity planning
Reconcile drive marketing GB with OS-reported GiB.
Debugging
Flip between hex, binary and decimal addresses.
Bandwidth math
Estimate transfer times across MB/s and Gbps figures.
Key formulas
- GB → GiB
GiB = GB × 10⁹ / 2³⁰ ≈ GB × 0.9313
Common mistakes
Confusing bits and bytes
Network speeds use bits (Mbps); file sizes use bytes (MB). Off by a factor of 8.
Did you know?
A 1 TB drive is 931 GiB
Same bytes — just decimal vs binary units. Nothing is missing.
Frequently asked
Why does my 1 TB drive show 931 GB in the OS?
Drive makers use the SI definition (1 TB = 10¹² bytes). Operating systems often display the same number in binary GiB (≈ 931 GiB). The drive isn't smaller — the units are different.
What's the difference between MB and MiB?
1 MB = 1,000,000 bytes (decimal). 1 MiB = 1,048,576 bytes (binary, 2²⁰).
