About Data Size Converter

Data Size Converter changes a size between bytes, the decimal units where a kilobyte is 1000 bytes, the binary units where a kibibyte is 1024 bytes, and bits.

It also gives the rounded human-readable form in both unit families. It runs in your browser.

How to use it

  1. Enter a value and its unit, or type something like 1.5 MB.
  2. Read the conversion table.
  3. Copy the value you need.

Common questions

What is the difference between MB and MiB?

A megabyte is 1000 kilobytes and a mebibyte is 1024 kibibytes. Storage is usually sold in decimal units, while memory and many tools report binary units.

How are bits handled?

One byte is eight bits. Network speeds are often in bits per second, so this helps convert to bytes.

How is the human-readable size rounded?

To two decimal places, then trailing zeros are trimmed.

Does anything leave my browser?

No. The tool runs entirely on this page.
