About Digital Storage

Digital storage covers the seven units used to describe file sizes, bandwidth and disk capacity: bits and bytes at the bottom, then kilobytes, megabytes, gigabytes, terabytes and petabytes. People land here for very concrete reasons: working out whether a video will fit on a drive, checking how much of a data allowance an upload will eat, sizing a backup, comparing what a hosting plan actually gives you, or reading a spec sheet that quotes one unit while the software reports another. The pages used most are gigabytes to megabytes, megabytes to gigabytes, terabytes to gigabytes and megabytes to kilobytes.

This is the one category with a genuine ambiguity in it, and it explains a question almost every computer user has asked. There are two conventions for what a prefix like kilo or mega means in storage. The decimal convention treats each step as a factor of 1000, matching how kilo and mega work everywhere else in measurement, and it is what drive manufacturers, network operators and most operating systems use when they advertise capacity or speed. The binary convention treats each step as a factor of 1024, because computers address memory in powers of two, and some software still reports sizes that way. That mismatch is exactly why a drive sold as a certain number of gigabytes shows up as a smaller number in some file managers: nothing is missing, the two sides are simply counting with different step sizes. This site uses the decimal convention, with 1000 to each step, which matches how storage and bandwidth are sold and labelled. The other thing worth watching is bits versus bytes. A byte is made of bits, and network speeds are almost always quoted in bits per second while file sizes are quoted in bytes, which is why a connection advertised with a big number downloads files at what feels like a much smaller one.

Every pair page shows the formula used, a worked example, and a reference table of the sizes people look up most. The pages are free, need no account, and run entirely in your browser, so no file name, size or figure you enter is uploaded to anything. If you want to know how long a transfer will take rather than how big it is, pair these with the time converter.

Frequently asked questions

Does this converter use 1000 or 1024 per step?

It uses 1000, the decimal convention. That matches how drive manufacturers, internet providers and most operating systems label capacity and speed, so the numbers here line up with what you see when you buy storage or bandwidth. The alternative binary convention uses 1024 per step and is still used by some software when reporting file sizes, which is where the two can disagree.

Why does my new drive show less space than advertised?

Because of the two conventions above. The manufacturer counts in decimal steps of 1000, while some file managers report in binary steps of 1024. The same physical capacity therefore produces a smaller-looking number on screen. No space has actually vanished; it is a labelling difference. A small amount is also genuinely taken by formatting and the file system itself, but the bulk of the gap is the counting convention.

What is the difference between a bit and a byte?

A bit is the smallest unit of digital information and a byte is a group of bits. The practical consequence is that internet speeds are almost always advertised in bits per second while file sizes are measured in bytes, so a connection with an impressive-sounding number transfers files at a much lower-looking rate. Watching the capitalisation helps, since an uppercase B usually means bytes and a lowercase b usually means bits.

Is anything I type here uploaded?

No. The conversion is plain arithmetic done in your browser with JavaScript, so the numbers never leave your device and no file is involved at all. These pages only convert figures you type in; they do not read, scan or upload anything from your computer. They are free, need no account, and have no usage limit.
