How to convert
Exact conversion factors in both directions, plus a worked example.
1 KB = 1000 B
1 B = 0.001 KB
To convert kilobyte to byte, multiply by 1000.
To convert byte to kilobyte, multiply by 0.001.
Example: convert 10 KB to B
10 × 1000 = 10000 B
About these units
Short background on the units used in this conversion.
Byte (B)
A byte is 8 bits — the standard unit for file sizes, RAM, and storage capacity in computing.
Bytes and their multiples describe hard drives, downloads, and memory on phones and computers.
Frequently asked questions
How many bytes are in one kilobyte?
One kilobyte equals 1,000 bytes. Multiply your kilobytes value by 1,000 to convert to bytes.
What is the conversion formula?
B = KB × 1,000The reverse is
KB = B × 0.001, using the same exact factors as this converter.Is this Kilobyte to Byte converter private?
