How to convert digital storage units

There are two answers to how many bytes are in a megabyte, and both are correct in their own context. Decimal, where a mega means a million, is what SI defines and what drive and network vendors use. Binary, where a mega means 1024 squared, is what operating systems display. Converting without saying which one you mean is how a 500GB drive becomes a support ticket.

This converter makes the base an explicit choice, and it also carries the bit and byte units side by side, so you cannot accidentally confuse a megabit with a megabyte.

  • Enter the value you want to convert.
  • Pick the source unit and the target unit, watching whether each is a bit or a byte.
  • Set the base: decimal (1 KB = 1000 B, SI and drive vendors) or binary (1 KiB = 1024 B, what your OS shows).
  • Read the converted value, and the full table of every other unit at the same time.
Tips

Getting a better result out of Digital Storage Converter

Specific settings and thresholds, not general advice.

  • The base toggle is the whole point of this tool. In decimal mode 1 kilobyte is 1000 bytes, which is what drive manufacturers, network engineers, and the SI standard mean. In binary mode 1 kilobyte is 1024 bytes, which is what Windows and most operating systems display. The gap compounds: a 1TB drive shows as roughly 931GB in Windows.
  • Watch the b and the B. A megabit is one eighth of a megabyte. Internet plans are sold in megabits per second, files are measured in megabytes, so a 100Mbps line downloads at about 12.5MB/s at best, and this is the single most common unit mistake in computing.
  • The strictly correct names for the binary units are kibibyte, mebibyte, and gibibyte (KiB, MiB, GiB), standardised by IEC in 1998. Almost nobody uses them in conversation, which is exactly why the toggle here has to exist.
  • Storage vendors are not lying when a 500GB SSD shows as 465GB. They are counting in decimal (500,000,000,000 bytes) while the operating system divides by 1024 three times. Use decimal mode to check a datasheet and binary mode to check what Explorer will show.
  • Bit and byte are the same in both bases, since neither has a prefix. Only the kilo, mega, giga, tera, and peta rows change when you flip the toggle.
Limits

What Digital Storage Converter does not do

The honest boundary, so you do not lose time finding it yourself.

  • Ten units only: bit, byte, and the kilo/mega/giga/tera/peta byte plus kilo/mega/giga bit forms. There is no terabit, petabit, exabyte, or nibble.
  • It converts sizes, not rates. There is no per-second bandwidth or transfer-time mode.
  • One conversion at a time. There is no bulk or list input.
  • It shows the answer at a fixed display precision, so very large or very small values may be rounded.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Why does my 1TB drive show as 931GB?

The manufacturer counts a terabyte as 1,000,000,000,000 bytes, which is the SI definition. Windows divides by 1024 four times and calls the result a GB, which gives 931. Neither is wrong, they are counting in different bases. Set this tool to decimal to read the datasheet, and binary to predict what the operating system will display.

How many megabytes are in a gigabyte?

1000 in decimal, 1024 in binary. That is a 2.4% gap at this one step, and it compounds at every prefix, so by the terabyte level the two answers differ by about 10%. If someone quotes you a size without saying which base, they are probably quoting decimal if it is hardware and binary if it is an operating system.

What is the difference between Mb and MB?

Eight times. A lowercase b is a bit, an uppercase B is a byte, and a byte is eight bits. Network speeds are quoted in bits per second and file sizes in bytes, so a 100Mbps connection tops out at roughly 12.5MB/s. Anyone who says their gigabit line downloads at a gigabyte a second is out by a factor of eight.

What is a kibibyte?

The IEC name for exactly 1024 bytes, abbreviated KiB, along with mebibyte (MiB) and gibibyte (GiB). It was standardised in 1998 to end the ambiguity, and it never caught on in speech. This tool uses the familiar names and asks you to pick the base instead, which is how the world actually talks.

Can I convert transfer speeds with this?

Not directly. This converts sizes, not rates. To work out a download time, convert the file size to bits, convert your line speed to bits per second, and divide. In practice halve your expectations for overhead: a 100Mbps line delivering a 1GB file takes well over the 80 seconds the arithmetic suggests.
