SI Decimal vs Binary: Why Two Different Standards?

When converting kilobytes to bytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:

SI decimal vs binary storage standards: base, kilobyte size and common users
Standard Base 1 KB equals Used By
SI Decimal 1000 1,000 bytes Hard drive manufacturers, macOS, network speeds
Binary (IEC) 1024 1,024 bytes Windows, Linux (partially), RAM specifications

Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard above the converter.

FAQs: Kilobyte to Byte Conversion

How many bytes are in 1 kilobyte?

1 Kilobyte (KB) equals 1,000 Bytes using the SI decimal standard.

How do I convert kilobytes to bytes?

Multiply the kilobyte value by 1,000 to get bytes. For example, 10 KB = 10,000 B.

Is a kilobyte bigger than a byte?

Yes. 1 KB = 1,000 B, so the kilobyte is the larger data storage unit.

What is Kilobyte (KB) commonly used for?

Text documents, small images, email attachments, configuration files.
