About Converting Kilobits to Bytes
Kilobit and Byte are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: Kilobit digital storage unit, and byte digital storage unit.
Formula
bytes = kilobits × 125
This factor comes from each unit's defined relationship to the category's base unit: 1 kilobit equals 1000 base units, and 1 byte equals 8 base units, so dividing one by the other gives the direct kilobit-to-byte factor of 125.
Simple example
1 kb × 125 = 125 B
1 kilobit = 125 bytes.
Real-world example
500 kb × 125 = 62,500 B
500 kilobits = 62,500 bytes.
Conversion table
| Kilobit (kb) | Byte (B) |
|---|---|
| 1 kb | 125 B |
| 8 kb | 1,000 B |
| 16 kb | 2,000 B |
| 64 kb | 8,000 B |
| 256 kb | 32,000 B |
| 1,000 kb | 125,000 B |
Reverse conversion: Byte to Kilobit
125 B × 0.008 = 1 kb
125 bytes = 1 kilobit.
kilobits = bytes × 0.008

Understanding the Kilobit (kb)
Kilobit digital storage unit.
Understanding the Byte
Byte (B) measures digital storage. A byte is 8 bits, the standard unit for addressing a single character of text in most computer architectures. It is classified as a Base digital storage unit.
Where it's used: Universal in computing
Uses of the Byte today
- Fundamental unit for file sizes and memory addressing
- Base unit from which all larger storage units (KB, MB, GB) are derived
History of the Byte
The byte emerged in the 1950s-60s as computer architectures converged on 8 bits as a practical size for representing a single character; IBM's System/360 (1964) was influential in cementing the 8-bit byte as an industry standard.
Historical origin. Byte was not the invention of a single named person; it developed through the process described above.
Byte — sources
- IEC 80000-13 — Defines the byte and its relationship to the bit.

Frequently asked questions
How many bytes are in 1 kilobit?
1 kilobit equals 125 bytes, using the exact defined conversion factor rather than an estimate.
How do I convert kilobit to byte?
Multiply the kilobit value by 125. The converter above does this instantly to whatever precision you set.
How do I convert byte back to kilobit?
Use the reverse factor: 1 byte equals 0.008 kilobits. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilobit?
Kilobit (kb) is a unit of digital storage.
What is a byte?
Byte (B) measures digital storage. A byte is 8 bits, the standard unit for addressing a single character of text in most computer architectures. It is classified as a Base digital storage unit.
Is the kilobit to byte conversion exact?
Yes. Both kilobit and byte are defined by fixed standards rather than physical artifacts, so the factor of 125 used above is exact to as many digits as you choose to display.
