bittoB
Convert bits (bit) to bytes (B).
Factor1 bit = 0.125 B
Converter
bit
Accepts numbers or expressions, e.g. 150 + 14.7
Result
B
Rendered to 6 significant figures.
Formula
Formula
B = bit × 0.125
Multiply any value in bits by 0.125 to obtain the value in bytes.
Worked example
Convert 8 bit to B.
- 01Start with 8 bit.
- 02Multiply by the conversion factor: 8 × 0.125 = 1 B.
Result8 bit = 1 B

FAQ
What is the conversion factor from bit to B?
1 bit equals 0.125 B. To convert, multiply the value in bits by 0.125.
How do I convert 1 bit to B?
1 bit = 0.125 B. For any value, multiply by 0.125.
How do I convert B back to bit?
Divide by the same factor — or equivalently, multiply by 8. So 1 B = 8 bit.
When would I need to convert bit to byte?
Digital data-storage conversions between bit and B are routine in IT, networking, storage-array engineering, datacenter capacity planning, cloud-cost reconciliation, embedded systems and scientific data acquisition. Decimal (SI) units (kB, MB, GB, TB, PB) use base-10 multiples: 1 kB = 1,000 bytes. Binary (IEC 80000-13) units (KiB, MiB, GiB, TiB, PiB) use base-2 multiples: 1 KiB = 1,024 bytes. 1 byte = 8 bits exactly across both ladders. This category is storage size only — it does NOT cover data-transfer rate (bit/s, MB/s), download-time, bandwidth, compression-ratio assumptions or storage-pricing calculators, all of which require additional information beyond a single linear factor.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
