Frequently asked questions

What is the source unit in this conversion?

The source unit is the byte (B), a unit of digital storage equal to 8 bits, commonly used to represent a single character.

What is the destination unit in this conversion?

The destination unit is the kilobyte (KB), a decimal (SI) unit of digital storage equal to 1,000 bytes, or 8,000 bits.

How do I convert bytes to kilobytes?

Multiply the byte value by 0.001 to get kilobytes. For example, 4 B × 0.001 = 0.004 KB.

Is the byte to kilobyte conversion exact?

It's exact under the decimal (SI) definitions used here, where each decimal storage prefix is a fixed factor of 1,000 from the next (and bytes are a fixed factor of 8 from bits).

Where is this conversion commonly used?

It's used for describing file sizes, storage drive capacity, RAM, network bandwidth, and internet data plans or downloads.

Can I convert kilobytes back to bytes?

Yes. Divide the kilobyte value by 0.001 to get bytes.

About this conversion

This page converts bytes (B), a unit of digital storage equal to 8 bits, commonly used to represent a single character, into kilobytes (KB), a decimal (SI) unit of digital storage equal to 1,000 bytes, or 8,000 bits.

This conversion is used constantly when checking file sizes, storage drive and memory capacity, network bandwidth, and mobile or broadband data plan allowances.

The formula is KB = B × 0.001, based on the fixed relationship between these two digital storage units.

It's exact under the decimal (SI) definitions used here, where each decimal storage prefix is a fixed factor of 1,000 from the next (and bytes are a fixed factor of 8 from bits).

Digital storage prefixes follow the International System of Units (SI) for decimal units and the International Electrotechnical Commission (IEC) recommendations for binary units, keeping decimal and binary quantities unambiguous.
