Data Size Converter

Digital storage is measured in a ladder of units — bytes, kilobytes, megabytes, gigabytes and terabytes — and it is easy to lose track of how they relate. The Data Size Converter translates a value between all of them, so you can make sense of a file size, an upload limit, a download or a storage quota in whichever unit you prefer.

How to use the Data Size Converter

1. Enter a value and choose its unit.
2. See it expressed across all the other units.
3. Copy the figure you need.

Making storage numbers meaningful

Numbers like "2,400,000 KB" are hard to picture, but "about 2.4 GB" is instantly clear. Converting between units helps you compare a file against an email attachment limit, judge whether a folder fits on a drive, or understand a hosting plan's quota. Each step up the ladder multiplies by 1,024 in the binary convention computers traditionally use, and this converter applies that consistently so your figures line up with how your operating system reports them.

Tips on data sizes

• Each unit is 1,024 of the one below in the binary convention.
• A byte is eight bits; file sizes are in bytes, internet speeds often in bits.
• Round for readability: "1.5 GB" communicates better than the raw byte count.
• Watch for KB vs Kb — capital B means bytes, lowercase b means bits.

All conversion happens in your browser, so nothing is uploaded.
