Frequently Asked Questions
What is the difference between binary and decimal data units?
Binary units use a base of 1024 (1 KB = 1024 bytes) and are traditionally used by operating systems and memory. Decimal units use a base of 1000 (1 KB = 1000 bytes) and are commonly used by storage manufacturers and network speeds.
Why does my hard drive show less space than advertised?
Hard drive manufacturers use decimal units (1 GB = 1,000,000,000 bytes), while your operating system typically uses binary units (1 GB = 1,073,741,824 bytes). This difference means a 500 GB drive shows approximately 465 GB in your OS.
What are the standard data size units?
From smallest to largest: bit, byte (8 bits), kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), petabyte (PB), and exabyte (EB). Each step is 1024 times larger in binary or 1000 times in decimal.
Is my data safe?
Yes! All processing happens entirely in your browser. Your data is never sent to any server. No data is collected, stored, or transmitted.
When should I use binary vs decimal conversion?
Use binary (1024-based) for RAM, file sizes shown by operating systems, and programming contexts. Use decimal (1000-based) for storage capacity labels, network transfer rates, and telecommunications.
