💡 The Crucial Difference: Decimal (SI) vs. Binary (IEC)
In the International System of Units (SI), prefixes represent powers of 10:
- 1 KB = 1,000 Bytes (10³)
- 1 MB = 1,000,000 Bytes (10⁶)
- 1 GB = 1,000,000,000 Bytes (10⁹)
- 1 TB = 1,000,000,000,000 Bytes (10¹²)
Used by storage drive manufacturers (WD, Seagate, Samsung), network bandwidth (Mbps), and macOS.
In computer architecture, memory and files are addressed in powers of 2:
- 1 KiB = 1,024 Bytes (2¹⁰)
- 1 MiB = 1,048,576 Bytes (2²⁰)
- 1 GiB = 1,073,741,824 Bytes (2³⁰)
- 1 TiB = 1,099,511,627,776 Bytes (2⁴⁰)
Used by Microsoft Windows, RAM hardware, CPU caches, and Linux kernel utilities.
How It Works
- Normalizes the input value to exact base bytes.
- Computes simultaneous conversions across SI decimal (powers of 1000) and IEC binary (powers of 1024) standards.
- Highlights the exact discrepancy between disk manufacturer specifications (SI) and OS reporting (IEC).
Practical Example
Frequently Asked Questions
What is the difference between KB and KiB?
KB (Kilobyte) is based on the decimal standard (10^3 = 1,000 bytes) established by the International System of Units (SI). KiB (Kibibyte) is an IEC standard binary prefix equal to 2^10 = 1,024 bytes.
Why does my hard drive show less capacity in Windows?
Hard drive manufacturers market capacity using decimal units (1 TB = 1,000,000,000,000 bytes). Microsoft Windows measures and reports capacity in binary gigabytes (Gibibytes, 1,024^3 = 1,073,741,824 bytes) while improperly labeling the unit as "GB".
