Storage Converter
Enter a storage amount in any unit. This tool shows it in every other unit at once. It uses decimal sizes, the same ones drives and files are labeled with.
Enter a storage amount to see every unit.
These are decimal units, where each step is 1000. Drives and files use them. Your system may count in binary (1 GiB = 1024 MiB), which reads a little smaller.
How It Works
Type a number and pick its unit. The tool converts to a base of bytes, then shows the value in KB, MB, GB, TB, and PB together.
Results update as you type. Change the unit and the whole list refreshes.
Each step between units is 1000 in decimal terms. So 1000 KB is 1 MB, 1000 MB is 1 GB, and 1000 GB is 1 TB.
The Formula
Every value first converts to plain bytes. A 2 GB file is 2,000,000,000 bytes.
To show another unit, divide by that unit in bytes. So 2,000,000,000 bytes is 2000 MB or 0.002 TB.
Operating systems sometimes count in binary steps of 1024, which is why a drive can read smaller than its label. More on that below.
Worked Example
Say you have a 2.5 TB drive and want the figure in GB.
2.5 TB in decimal is 2.5 times 1000, which is 2500 GB.
The tool also shows it as 2,500,000 MB, so you can match whatever unit a program reports.
Common Uses
- Matching a drive size against what a backup tool reports.
- Converting a cloud plan quoted in GB into TB for comparison.
- Working out how many MB fit in a larger GB or TB allowance.
- Translating a file manager figure into the unit you actually need.
