How to Convert Bytes to Kilobits
To convert bytes to kilobits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. You might also need: Kb to B calculator.
B is a byte-based unit used for measuring file sizes and storage capacity. Check out our B to Kib converter.
Kb is a bit-based unit—multiply bytes by 8 to get bits. Check out our YiB to Kb.
1 B = 0.008 Kb (using SI decimal standard) — or equivalently, 1 Kb = 125B.
B to Kb Conversion Formula
// Convert B to Kb
Kb = B × 0.008
// Reverse: Convert Kb to B
B = Kb × 125
B to Kb Conversion Examples
100 B = 0.8 Kb
256 B = 2.048 Kb
500 B = 4 Kb
1,000 B = 8 Kb
2,048 B = 16.384 Kb
What Is a Byte?
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). See also: Kibibytes in Pebibits.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our converting Megabits Per Second to Kilobytes Per Second.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) Related: B to Zib conversion rate.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.
What Is a Kilobit?
A kilobit is 1,000 bits. Often used for slower network connections and legacy data rates. You might also need: calculate Yib to Kb.
The kilobit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our how many Gibibits in a TB.
Common uses: Dial-up modem speeds, low-bandwidth connections, audio bitrates Learn more: how many Tibps in Tebibytes Per Second.
1 Kb = 1,000 bits = 125 bytes.
The kilobit can be abbreviated as Kb; for example, 1 kilobit can be written as 1 Kb.

💡 Storage Engineer Tip
Multiply bytes by 8 to get bits. A 10 MB file requires 80 Mb of bandwidth—essential when calculating transfer times over network links.
