Btobit
Convert bytes (B) to bits (bit).
Factor1 B = 8 bit
Converter
B
Accepts numbers or expressions, e.g. 150 + 14.7
Result
bit
Rendered to 6 significant figures.
Formula
Formula
bit = B × 8
Multiply any value in bytes by 8 to obtain the value in bits.
Worked example
Convert 1 B to bit.
- 01Start with 1 B.
- 02Multiply by the conversion factor: 1 × 8 = 8 bit.
Result1 B = 8 bit

FAQ
What is the conversion factor from B to bit?
1 B equals 8 bit. To convert, multiply the value in bytes by 8.
How do I convert 1 B to bit?
1 B = 8 bit. For any value, multiply by 8.
How do I convert bit back to B?
Divide by the same factor — or equivalently, multiply by 0.125. So 1 bit = 0.125 B.
When would I need to convert byte to bit?
Digital data-storage conversions between B and bit 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).
