Speicherplatz-Rechner

Storage sizes are a perennial muddle. The drive maker advertises a terabyte, the operating system shows less, and nobody knows off the top of their head how many megabytes are actually in a gigabyte. The storage calculator clears this up: you enter a value and a unit, and it instantly converts it into every other unit from bytes to exabytes, neatly in a table.

The root of the whole misunderstanding is the difference between binary and decimal. Computers work in powers of two, so with the factor 1024: 1 kibibyte is 1024 bytes, 1 gibibyte is 1024 mebibytes. Storage makers, on the other hand, advertise in round thousands, so with the factor 1000: 1 kilobyte is 1000 bytes. That is exactly why your 1 TB drive looks smaller in the system. The calculator separates both worlds with a switch and names the units correctly, so KiB and GiB in binary mode, KB and GB in decimal mode.

So the numbers do not stay abstract, there are the vivid comparisons. The calculator translates your storage size into everyday quantities: how many photos of five megabytes each, how many hours of high-quality music, how many episodes at a good resolution, or how many text documents fit in. That gives you an instant feel for whether 256 gigabytes is a lot or a little for you.

The calculator is handy for copying too. You grab any single value into the clipboard with one click, or you copy the entire conversion table in one go. That saves typing when you want to carry a size into documentation, a quote or a message.

You can enter numbers with a comma or a dot, whichever suits you. Enter something nonsensical, like letters or a negative number, and instead of a dry warning you get a little quip with a wink. And the compact summary at the bottom additionally shows your size in the other counting scheme, so you see binary and decimal right next to each other.

The calculator runs entirely in your browser. There is no account, no signup and no data transfer. Your entries stay on your device, and the tool works offline too. Exactly as data-frugal as a simple converter should be.
