Converter of data storage units
Data units converter. Converts bits, bytes, megabytes, gigabytes itd. All known units of data in two different bases: 1000 and 1024. This calculator handles some less known data units: nibbles, octets, pixels (24/48-bit), words, quads, long-words etc.

Symbolic algebra

ⓘ Hint: This calculator supports symbolic math. You can enter numbers, but also symbols like a, b, pi or even whole math expressions such as (a+b)/2. If you still don't sure how to make your life easier using symbolic algebra check out our another page: Symbolic calculations

bitsShow sourcebbbShow source...\text{...}-The smallest information unit. A bit can take one of two states, depending on the context:
  • true and false,
  • 1 and 0,
  • -1 and 1,
  • yes and no,
  • etc.

Some facts#

  • The most basic and smallest unit of information is one bit.
  • Another common unit is - byte. It's equivalent to 8 bits (octet).
  • However, single byte had different meaning in the past. In the first years of computer era single byte had no clear definition. It was usualy defined as number of bits processed by computer at one time. This definition is obsolete now and has only historical meaning. One byte is always equivalent to 8 bits nowadays.
  • Abbreviation corresponding to one bit is a lowercase b (1b), and capital letter B (1B) for one byte. Using the same character to denote two different units often leads to confusions.
    For example, bandwidth of internet connection is usually given in bits per seconds (and derived units), for example: 10Mb/s or 10Mbps (10 megabits per second). Less oriented users often read it incorrectly as 10 megabytes per second. To avoid that, common pattern is to use "10 Mbit" instead of "10 Mb".

How to convert#

  • Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
    Examples:
    • 1000000
    • 123,23
    • 999.99999
  • Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
  • And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
