Data Storage Converter
Convert between bytes, KB, MB, GB, TB and more.
What is a Data Storage Converter?
A data storage converter converts between units of digital storage: bits, bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), and their binary equivalents (kibibytes, mebibytes, gibibytes). These conversions are essential for developers, system administrators, and anyone managing files or storage capacity.

Decimal vs Binary Units
Storage manufacturers typically use decimal units (1 KB = 1,000 bytes) while operating systems often use binary units (1 KiB = 1,024 bytes). This discrepancy causes the "missing storage" effect — a 1TB drive shows as ~931GB in Windows.
Common Reference Points
1 byte = 8 bits. 1 KB = 1,000 bytes (or 1 KiB = 1,024 bytes). 1 MB = 1,000,000 bytes. 1 GB = 1,000,000,000 bytes. Average MP3: ~4MB. Average movie (HD): ~4–8GB. Average SSD: 256GB–2TB.
Frequently Asked Questions
Why does my 1TB hard drive show less space in Windows?
Drive manufacturers use 1TB = 1,000,000,000,000 bytes (decimal), while Windows reports in binary (1TB = 1,099,511,627,776 bytes), so 1TB shows as approximately 931GB.
What is the difference between a bit and a byte?
1 byte = 8 bits. Network speeds are typically measured in bits per second (Mbps), while file sizes are measured in bytes (MB).
