About This Tool

Storage Converter — Convert Digital Storage Units Instantly

Understanding digital storage sizes is essential for developers, IT professionals, system administrators, and anyone managing files or computing resources. Our Storage Converter converts between all digital storage units with precision, handling both decimal (SI) and binary (IEC) standards.

Supported Storage Units

Decimal (SI) units (powers of 10, used by hard drive manufacturers and network speeds):

  • Bit (b)
  • Byte (B) = 8 bits
  • Kilobyte (KB) = 1,000 bytes
  • Megabyte (MB) = 1,000,000 bytes
  • Gigabyte (GB) = 1,000,000,000 bytes
  • Terabyte (TB) = 1,000,000,000,000 bytes
  • Petabyte (PB)
  • Exabyte (EB)

Binary (IEC) units (powers of 2, used by operating systems):

  • Kibibyte (KiB) = 1,024 bytes
  • Mebibyte (MiB) = 1,048,576 bytes
  • Gibibyte (GiB) = 1,073,741,824 bytes
  • Tebibyte (TiB) = 1,099,511,627,776 bytes

Why Two Standards?

The difference between KB and KiB (or GB and GiB) causes widespread confusion:

  • Hard drive manufacturers use decimal (1 GB = 1,000,000,000 bytes)
  • Operating systems use binary (1 GB = 1,073,741,824 bytes)

This is why a "1 TB" hard drive shows as approximately 931 GB when connected to a Windows or macOS system — the OS uses binary counting.

Common Storage Conversions

  • 1 byte = 8 bits
  • 1 KB = 1,000 bytes (SI) or 1,024 bytes (IEC)
  • 1 MB = 1,000 KB (SI) or 1,024 KiB (IEC)
  • 1 GB = 1,024 MB (in common usage) or 1,000,000,000 bytes (SI)

Use Cases

File management: Understand and compare file sizes across documents, photos, videos, and applications.

Cloud storage planning: Calculate how much cloud storage you need for your data.

Network speed vs. file size: Convert between bits and bytes to understand download/upload time calculations (internet speeds are in bits/sec; file sizes are in bytes).

Database administration: Calculate database table sizes and storage requirements.

❓ Frequently Asked Questions

Hard drive makers use decimal 1 TB = 1,000,000,000,000 bytes. Windows uses binary, where 1 TB = 1,099,511,627,776 bytes. Dividing: 1,000,000,000,000 ÷ 1,073,741,824 ≈ 931 GiB.
1 KB (kilobyte, SI decimal) = 1,000 bytes. 1 KiB (kibibyte, IEC binary) = 1,024 bytes. The IEC introduced KiB to eliminate this ambiguity, though KB is still used informally for both.
In decimal (SI): 1 GB = 1,000,000,000 bytes. In binary (IEC): 1 GiB = 1,073,741,824 bytes. The difference is about 7.4%.
Network speeds are measured in megabits per second (Mbps), while file sizes are in megabytes (MB). 1 MB = 8 Mb. To download a 100 MB file at 100 Mbps, it takes 8 seconds.
1 petabyte = 1,000 terabytes (decimal) = 1,000,000 gigabytes. Major cloud providers and data centers typically store data at petabyte scale.
Divide the MB value by 1,000 (decimal) or 1,024 (binary/IEC). For example, 5,000 MB ÷ 1,000 = 5 GB (decimal), or 5,120 MiB ÷ 1,024 = 5 GiB (binary).
