How It Works & Underlying Concept

Digital data storage measurement uses two different conventions: SI decimal standards (where 1 Kilobyte = 1,000 Bytes) and IEC binary standards (where 1 Kibibyte = 1,024 Bytes). Storage manufacturers label drives using decimal 1000-base prefixes, whereas operating systems like Windows calculate capacity using binary 1024-base memory addressing.

Mathematical Formula / RuleBinary: 1 GiB = 1024 MiB = 1,048,576 KiB | Decimal: 1 GB = 1000 MB = 1,000,000 KB
Quick Instructions
1Enter the digital storage value.
2Choose your standard: Binary (1024) for OS file systems, or Decimal (1000) for hard drive marketing labels.
3Select source and destination units to inspect the conversion.

Key Capabilities

  • Toggle between Binary IEC (1024 base: KiB, MiB, GiB) and Decimal SI (1000 base: KB, MB, GB)
  • Supports Bits, Bytes, KB, MB, GB, TB, and PB
  • Explains why hard drives appear smaller in operating systems
Real-World Example

Hard Drive Capacity Mismatch

A consumer buys a 1 Terabyte (TB) external hard drive and notices their computer reports only ~931 GB of usable space.

Step 1:Manufacturer decimal capacity: 1,000,000,000,000 Bytes.
Step 2:Dividing by binary 1024^3 (1,073,741,824) equals 931.32 GiB.
Result: A 1 TB decimal drive provides 931.32 GiB of binary operating system capacity.
Technical Notes & Limits
  • Storage values must be non-negative real numbers.

Frequently Asked Questions

Why does my 500GB SSD show up as only 465GB in Windows?▾
Drive manufacturers advertise 500 GB using 1000-byte multipliers (500,000,000,000 bytes). Windows divides this number by 1024^3, displaying 465.66 GiB.
What is the difference between a bit and a byte?▾
A bit is the smallest binary unit (0 or 1). A byte consists of exactly 8 bits.
