Data Storage Converters
Convert storage-size units across decimal and binary systems, including bit and byte families from base units up to peta-scale. This hub keeps size-only conversions separate from transfer-rate pages and makes SI vs IEC differences explicit.

Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.
Public interfaces
Machine access
Conversions in this hub are represented by the canonical data-storage family and its registered source and target units.
Its 462 published directions use the same canonical engine through the website, JSON API, OpenAPI and WebMCP.
API & Agent documentationExplanation
This hub separates storage-size conversions from transfer-rate conversions. Every factor is normalized through exact bit counts, then mapped across decimal (base-10) and binary (base-2) prefix systems. Dedicated mirror pages make SI vs IEC comparisons explicit, especially for MB vs MiB, GB vs GiB, and byte-vs-bit routes where the exact 8-bit relationship matters.
Questions & answers
Frequently Asked Questions
What is the difference between MB and MiB?
MB is decimal (1,000,000 bytes) while MiB is binary (1,048,576 bytes). The names look similar but the scaling model is different.
Why is this separate from data transfer rate?
Storage is an amount of data, while transfer rate adds time (per second). This hub converts size-only units.
Are bit and byte conversions exact?
Yes. Bit-to-byte mapping is exact: 1 byte equals 8 bits, then prefix scaling is applied according to decimal or binary definitions.
