How to use the data storage converter
This data storage converter lets you switch between bytes and larger units in one place, with support for both binary (1024-based) and decimal (1000-based) systems. Choose the unit you are converting from and the unit you want to convert to, enter a non-negative size, and click "Convert" to see the result. A "Swap" button reverses the from and to units. All conversions use bytes as the base, so the tool stays consistent whether you mix binary and decimal units.
Data storage conversion is useful whenever you work with file sizes, disk space, or device capacity. Operating systems (Windows, macOS, Linux) usually display sizes in binary units: 1 KB = 1024 bytes, 1 GB = 1024 MB. Storage manufacturers often use decimal units: 1 kB = 1000 bytes, 1 GB = 1000 MB. That is why a "1 TB" hard drive can appear as about 931 GB in Windows—both numbers are correct, but they use different bases. This converter includes labels like "KB (binary, 1024)" and "GB (decimal, 1000³)" so you can choose the right system and avoid confusion.
The converter runs entirely in your browser. There is no sign-up, no download, and no delay. It is designed to be mobile-friendly: the two-column layout stacks on small screens, inputs have a comfortable touch size, and the result appears next to your input. Results are shown with up to six decimal places when needed. Use it to compare cloud storage plans, understand file sizes, or explain why a new drive shows less capacity than the box says.
