Data Storage Converter - Convert Bytes, KB, MB, GB & TB

Use this free data storage converter to convert between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. Choose binary (1024-based) or decimal (1000-based) conversion depending on your use case.

How does the Data Storage Converter work?

This tool converts your input to bytes using the selected base, then scales it into every other unit. Operating systems and RAM typically use base-1024 (binary) counting, while storage manufacturers and network speeds typically use base-1000 (decimal, SI) — which is why a "1 TB" hard drive shows less space than expected in your OS.
