Bits to bytes – convert b to B
Convert bits to bytes (b to B) to understand download speeds, file sizes and data usage. This page opens the main data converter with bits → bytes pre-selected so you can see how many bytes your stream of bits really represents.
Open the interactive bits → bytes converter:
Use main converter (b → B) or switch to bytes → bitsThe homepage lets you move between bits, bytes, KB, MB, GB and TB using consistent binary prefixes, ideal for internet and storage maths.
Quick reference: bits to bytes
By definition, 1 byte = 8 bits. That means: bytes = bits ÷ 8. Some common values:
| Bits (b) | Bytes (B) |
|---|---|
| 8 b | 1 B |
| 80 b | 10 B |
| 800 b | 100 B |
| 8000 b | 1000 B |
| 64000 b | 8000 B |
| 8000000 b | 1 000 000 B |
Bits to bytes conversion formula
The simple formula for converting bits to bytes is:
Bytes = Bits ÷ 8
Examples:
- 64 bits ÷ 8 = 8 bytes
- 1024 bits ÷ 8 = 128 bytes
- 65536 bits ÷ 8 = 8192 bytes
Why convert bits to bytes?
You’ll convert bits to bytes when you:
- Compare an internet speed in Mb/s with file sizes in MB or GB.
- Estimate download times for games, films or backups.
- Read networking specs (often in bits) but think in bytes and kilobytes.
- Double-check that marketing “megabits” match real storage numbers.
