What the Data Storage Converter does
This tool converts between digital storage units so you can compare file sizes, drive capacities, and data plans without doing the math by hand. It covers bits and bytes, the decimal units kilobyte through petabyte (KB, MB, GB, TB, PB), and the binary units kibibyte through tebibyte (KiB, MiB, GiB, TiB). That makes it useful for checking download sizes, planning backups, sizing cloud storage, or understanding why a drive reports a different number than its label.
How to use it
- Type the amount in the Value box.
- Set From to the unit you have (for example MB).
- Set To to the unit you want (for example GB).
- Press Convert to see the result below.
Decimal vs binary
The key thing to know is that storage has two counting systems. Decimal units step by 1000 (1 MB = 1000 KB) and are common on packaging and in networking. Binary units step by 1024 (1 MiB = 1024 KiB) and are common inside operating systems. This converter keeps them separate so your numbers stay correct, and it never sends anything anywhere because the math happens locally in your browser.
Frequently asked questions
- Does it handle both decimal (MB) and binary (MiB) units?
- Yes. It includes decimal units (KB, MB, GB, TB, PB) based on powers of 1000, and binary units (KiB, MiB, GiB, TiB) based on powers of 1024. Pick whichever your context uses, storage makers usually quote decimal, operating systems often show binary.
- Why does my drive show less space than the label says?
- A drive sold as 1 TB uses decimal (1,000,000,000,000 bytes), but many systems report space in binary (TiB), which is larger per unit, so the same drive looks like about 0.91 TiB. Nothing is missing, it is just two ways of counting.
- Is my data uploaded anywhere?
- No. The conversion runs entirely in your browser, so nothing you type is sent or stored. There is no account and no limit.
