Data Rate Unit Converters
Convert bit and byte rates while keeping the 8-bits-per-byte relationship and decimal or binary prefixes 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-rate family and its registered source and target units.
Its 210 published directions use the same canonical engine through the website, JSON API, OpenAPI and WebMCP.
API & Agent documentationExplanation
Network links are usually advertised in bits per second, while file transfers are often displayed in bytes per second. A capital B means byte and a lowercase b means bit. Decimal prefixes such as Mbps use powers of 1,000, while binary-prefixed byte rates such as MiB/s use powers of 1,024. Real throughput can be lower because of protocol overhead, congestion, storage speed, and encoding.
Questions & answers
Frequently Asked Questions
How many bits are in one byte?
Exactly 8 bits.
Is Mbps the same as MB/s?
No. Mbps is megabits per second; MB/s is megabytes per second.
Why is actual download speed lower than the converted link rate?
Protocol overhead, congestion, server limits, Wi-Fi conditions, and storage performance reduce real throughput.
