About bytes and bits
Byte (B)
A byte is 8 bits. It is the basic unit of file sizes and memory.
Bit (bit)
A bit is the smallest unit of digital information: a single 0 or 1. It is used for network speeds and low-level data sizes.
Both are units of digital information; the base unit used internally is bit.
Notes
- Decimal: 1 kB = 1000 bytes, 1 MB = 1000 kB, 1 GB = 1000 MB. Binary: 1 KiB = 1024 bytes, 1 MiB = 1024 KiB, 1 GiB = 1024 MiB.
- 1 TB = 1000 GB = 10¹² bytes and 1 TiB = 1024 GiB = 2⁴⁰ bytes (1,099,511,627,776 bytes).
- 1 byte = 8 bits. Data rates are not yet included. Quantities cannot be negative.
B to bit FAQs
How do I convert bytes to bits?
Multiply the number of bytes by 8 to get bits. For example, 25 B × 8 = 200 bit.
How many bits are in one byte?
1 B = 8 bit and 1 bit = 0.125 B. To go the other way, use the bits to bytes converter.
How many bits are in 10 bytes?
10 B = 80 bit, rounded to 6 significant digits. Change the value in the converter above for any other amount.
Is the B to bit conversion exact?
Yes. The factor 8 follows directly from the unit definitions (A byte is 8 bits; a bit is the smallest unit of digital information: a single 0 or 1), so the only rounding is in the digits you choose to display.
What is the difference between bytes and bits?
A byte is 8 bits. It is the basic unit of file sizes and memory. A bit is the smallest unit of digital information: a single 0 or 1. It is used for network speeds and low-level data sizes.
