How to use the Digital Storage

Enter a data storage size, select the current unit (bytes, KB, MB, GB, TB, etc.), choose your target unit, and get instant conversion. Perfect for file sizes, storage devices, and data management.

Formula

Decimal (KB, MB, GB, TB, PB): each step is ×1,000. value_in_bytes = input × 1,000ⁿ
Binary (KiB, MiB, GiB, TiB, PiB): each step is ×1,024. value_in_bytes = input × 1,024ⁿ
Bits: 1 byte = 8 bits

History & interesting facts

Did you know?

Operating systems often use binary (1,024) while manufacturers use decimal (1,000). This is why a 1 TB drive shows ~931 GB in Windows!

Origin & history

Digital storage started with kilobytes. The distinction between decimal (KB) and binary (KiB) was formalized in 1998 by the IEC.

Fascinating facts

  1. 1

    1 KB = 1,000 bytes (decimal) vs 1 KiB = 1,024 bytes (binary)

  2. 2

    1 MB = 1,000 KB or 1,000,000 bytes

  3. 3

    1 GB = 1,000 MB or 1 billion bytes

  4. 4

    1 TB = 1,000 GB or 1 trillion bytes

  5. 5

    Windows reports sizes in binary units (but labels them GB); macOS has used decimal since 2009

  6. 6

    Flash drives/SSDs: Often use decimal for higher advertised capacity

Frequently asked questions

What is the difference between KB and KiB?

1 KB = 1,000 bytes (decimal), while 1 KiB = 1,024 bytes (binary). Manufacturers use decimal, OS often report binary.

Why does my 1TB drive show 931 GB?

Manufacturers list storage in decimal (1 TB = 1 trillion bytes), but Windows divides by 1,024³ and still labels the result "GB". 1,000,000,000,000 ÷ 1,073,741,824 ≈ 931 GiB.

How many megabytes are in 1 gigabyte?

1 GB = 1,000 MB (decimal). In binary, 1 GiB = 1,024 MiB.
