Everything about KB


According to abbreviationfinder, KB is the abbreviation for Kilobyte which is a computing unit of measurement equivalent to 1024 bytes of computer memory or the capacity of any type of physical storage device. For example, a device that has 256K capacity can store approximately 262,144 bytes or characters at a time.


Despite being a term of daily use in the field of computing, the term kilobyte does not appear in the Dictionary of the Royal Spanish Academy. It is a computer storage unit that is symbolized as Kb or KB depending on the place and the use that is given to it. The International System of Units has established this and another series of measures in the field of computing within these we can mention some such as the megabyte, the gigabyte, the terabyte among others. Applying the definition of the binary prefix, one kilobyte would be equivalent to 2 bytes raised to the tenth power, on the other hand if the definition of the international system of units is appliedone kilobyte would equal 10 bytes cubed; In other words, if we use the binary system, one kilobyte would be exactly 1024 bytes, it is worth noting that in principle 1000 bytes were used as an average for one kilibyte, as the use of computers became popular, the term stipulated by the International System was misused. Units, so at present this approximate of 1000 bytes is used to refer to a kilobyte and not 1024 bytes as it should be. Many specialists have proposed to use the term Kivi which means 1024 in this way this new term would make exact reference to 1024 bytes.


In 1998 a modification to the existing legislation was carried out until that time to begin to work with the measures that really fit the reality established by the International System of Units, however despite this these new measures are They have used very little so it is common for users to get confused by continuing to use the old legislation prior to 1998, even on occasions this has been extrapolated to professionals in the computer sector since on occasions we realize that a storage device It does not really have the capacity that it says it should have, this is largely due to the socks used and the wrong conception that users of them have.

1 KB (Kilobyte) 1024 B (bytes) 1 MB (Megabyte) 1024 KB (kilobytes) 1 GB (Gigabyte) 1024 MB (Megabytes) 1 TB (Terabyte) 1024 GB (Gigabytes)


To go from a larger unit to a smaller one, multiply by 1024.


To go from a smaller unit to a larger unit, divide by 1024.



  • How many MB of RAM does a 1GB computer have?

GB MB (multiply) 1GB x 1024MB = 1024MB

  • How many MB of RAM does a computer have that has 2GB?

GB MB (multiply) 2GB x 1024MB = 2048MB

  • How many MB of RAM does a computer have that has 3GB?

GB MB (multiply) 3GB x 1024MB = 3072MB

  • How many KB of RAM does a computer have that has 3GB?

GB MB KB (multiply) 3GB x 1024MB x 1024KB = 3145728KB

  • How many GB of RAM does a computer have that has 2048MB?

MB GB (split) 2048MB / 1024MB = 2GB

  • How many GB of RAM does a computer have that has 3145728KB?

KB MB GB (split) 3145728KB / 1024MB / 1024GB = 2GB
