Data Size Converters

Interchange bytes, KB, MB, GB, etc.

Decimal units (SI, 1000 bits)
Binary unit (IEC, 1024 digit)

What's the data size unit?

In the digital world, Data Size It is a measure of how much digital information is measured. The size of your computer hard drive, your mobile phone flow package, or your downloading software involves the conversion of data units. Understanding these units not only helps you to better manage storage space, but also makes more informed decisions when buying electronics.

SI units (decimal) vs IEC units (bidecimal)

This is the root cause of the phenomenon of “deflation” of storage capacity. There are two different sets of conversion criteria:

  • Decimal unit (SI): Take 1000 for the entry base. Example: 1 KB = 1,000 Bytes, 1 MB = 1,000 KB。 This is a common standard for hard disk manufacturers (e.g., Higher, Western Data) and network transmission (e.g., bandwidth).
  • Binary units (IEC): Adopts 1024 as the entry base. For example: 1 KiB = 1,024 Bytes, 1 MiB = 1,024 KiB. This is the operating system. Windows, MacOS, Linux) calculates the actual standard used for the hourly hours of the file.

Why does a TB hard drive show 931 GB on the computer?

It's a very classic question. Harddisk manufacturer calculated on a decimal basis, which is considered to be 1 TB = 1,000,000,000,000 bytes. And... Windows operating systems are calculated on a binary basis:

  1. 1,000,000,000,000 / 1024 = 976,562,500 KB
  2. 976,562,500 / 1024 = 953,674 MB
  3. 953,674 / 1024 = 931.32 GB

So your hard drive is not "shrunk," but it's the result of different calculations. This tool shows the results of both sets of criteria, and helps you to dispel this confusion.

Common storage unit conversion tables (decimal)

  • 1 Byte (B) = 8 Bits (b)
  • 1 Kilobyte (KB) = 1,000 Bytes
  • 1 Megabyte (MB) = 1,000 KB
  • 1 Gigabyte (GB) = 1,000 MB
  • 1 Terabyte (TB) = 1,000 GB
  • 1 Petabyte (PB) = 1,000 TB

How to use this tool?

Just enter the value you want to convert in the input box and select the corresponding original unit. This tool immediately calculates the equivalent of all other commonly used units for you.
