Bytes to Bits Converter
Convert bytes (B) to bits (bit) with the exact data storage formula, worked examples, and a common-values table.
Exact conversion
Bytes to bits formula
bit = B × 8
1 B equals 8 bit. 10 B equals 80 bit.
About these units
- B
- Byte, a common storage unit made of 8 bits.
- bit
- Bit, the smallest binary data unit.
Before you use the result
B to bit context and checks
- Best use
- Use data-storage conversions for file sizes, drive capacity, backups, memory cards, and software download estimates.
- Common mistake
- Decimal and binary prefixes can differ. GB, GiB, MB, and MiB may not mean the same thing in hardware labels and operating systems.
- Precision note
- Keep the original value and prefix convention when comparing storage, because rounding can hide meaningful capacity differences.
Example check: 1 B converts to 8 bit. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.
