How to Convert Digital Storage Units (Decimal vs Binary)

  1. Input the digital data size.
  2. Select input unit: Bits, Bytes, KB, MB, GB, TB, PB.
  3. Toggle between SI decimal prefix (1,000 bytes) and binary IEC standard (1,024 bytes / KiB, GiB).

Digital Architecture Conversion Standards

  • 1 Byte = 8 Bits
  • Decimal (SI): 1 KB = 1,000 Bytes | 1 MB = 1,000,000 Bytes | 1 GB = 10⁹ Bytes
  • Binary (IEC): 1 KiB = 1,024 Bytes | 1 MiB = 1,048,576 Bytes | 1 GiB = 2³⁰ Bytes

Why Hard Drives Show Less Capacity in Windows

  • A manufacturer sells a 1 TB (1,000,000,000,000 bytes) drive. Windows measures in binary (GiB):
    1,000,000,000,000 / 1024³ = ~931.32 GiB.

Common Applications

  • Understanding drive capacity discrepancies in operating systems.
  • Cloud storage quota budgeting (AWS S3, Google Cloud, Azure).
  • Network bandwidth transfer time estimation.

Frequently Asked Questions

Why does a 500GB SSD show as 465GB in Windows?

Drive makers use decimal (1,000) while Windows uses binary (1,024). 500 × (1,000³ / 1,024³) = ~465.66 GiB.

What is the difference between MB and Mb?

Capital "B" stands for Bytes (storage), while lowercase "b" stands for Bits (network speed: e.g. 100 Mbps = 12.5 MB/s).
