About Memory Converter Online
This tool converts between digital storage and memory units: bits, bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, and their binary equivalents (kibibytes, mebibytes, gibibytes, etc.).
The KB vs KiB distinction matters when comparing storage capacities. Hard drive manufacturers use base-10 prefixes (1 KB = 1000 bytes) while operating systems typically report memory in base-2 (1 KiB = 1024 bytes). This tool supports both so you can accurately compare specifications.
Understanding the difference between base-10 and base-2 storage units is essential when calculating file storage requirements, comparing cloud storage plans, or evaluating hardware specifications.
How to use this tool
How to convert storage sizes (decimal)
Enter the size
Type the storage value in the Value field. Scientific notation like 1.5e6 is accepted.
Pick the source unit
From offers B, KB, MB, GB, TB — labelled "From (decimal)". This tool uses SI decimal prefixes (1 KB = 1000 B), not binary (1 KiB = 1024 B).
Pick the target unit
To offers the same units, also decimal. The factor between each step is exactly 1000 (B → KB → MB → GB → TB).
Press Run
Result is computed to 12 significant digits. Note: bandwidth in Mbps is *bits*, not bytes — this tool does not handle bit↔byte conversions.
