1 byte = 8 bits · open this conversion
Formula
bits = bytes × 8
Decimal units: 1 kB = 1,000 bytes. Windows reports storage in binary units (1 KiB = 1,024 bytes), which is why a 1 TB drive shows as roughly 931 GB.

Frequently asked questions
▸How many bits are in a byte?
One byte is 8 bits. bits = bytes × 8.
▸How do I convert bytes to bits?
Multiply the number of bytes by 8. For example, 10 B × 8 = 80 b.
▸What is the difference between bytes and bits?
Byte (B) and Bit (b) both measure data. Digital storage in decimal (SI) units, the same convention drive manufacturers and network speeds use: 1 kB is 1,000 bytes.
