Frequently Asked Questions
What's the difference between binary and decimal byte conversions?
Binary (IEC standard) uses 1024 as the multiplier: 1 KB = 1024 bytes, 1 MB = 1024 KB. Decimal (SI standard) uses 1000: 1 KB = 1000 bytes. Computer storage typically uses binary, while hard drive manufacturers often use decimal. Binary units are properly written as KiB, MiB, GiB, while decimal uses KB, MB, GB.
Why do hard drive sizes appear smaller than advertised?
Hard drive manufacturers use decimal (1000-based) calculations for capacity, but operating systems display using binary (1024-based) calculations. A '1 TB' drive (1,000,000,000,000 bytes) shows as approximately 931 GB in Windows because 1,000,000,000,000 ÷ 1024³ = 931.32 GiB.
Which conversion should I use for RAM and CPU cache?
Always use binary (1024-based) conversion for RAM and CPU cache. Computer memory is manufactured in powers of 2, so 8 GB of RAM is actually 8 GiB = 8,589,934,592 bytes (8 × 1024³), not 8,000,000,000 bytes.
How many megabytes are in a gigabyte?
In binary (IEC): 1 GB = 1024 MB. In decimal (SI): 1 GB = 1000 MB. For computer storage and memory, the binary conversion is most commonly used, so 1 GB = 1024 MB.
Is this bytes converter free?
Yes! Our bytes converter is completely free to use with unlimited conversions and no registration required.
Will my data be stored or shared?
No. All conversions happen entirely in your browser using JavaScript. No data is sent to our servers, stored in databases, or shared with anyone.
Does it work on mobile devices?
Absolutely! The bytes converter is fully responsive and works perfectly on smartphones, tablets, and desktop computers.
