Frequently asked questions
How many bytes are in a KB?
In SI units a kilobyte is 1,000 bytes; a kibibyte (KiB) is 1,024 bytes.
Why are there two definitions?
Computers address memory in powers of 2, so 1,024 (2^10) was used informally, and the IEC introduced KiB, MiB and GiB to remove the ambiguity.
What is 1 byte in kilobyte?
1 byte = 0.001 kilobyte (B to KB).
What is the formula to convert B to KB?
KB = B × 0.001. For example, 2,048 B × 0.001 = 2.048 KB.
How do I convert KB back to B?
Use the reverse converter: 1 kilobyte = 1,000 byte. Check: 2.048 KB converts back to 2,048 B.
