A cloud storage bill listing usage in TB, a training dataset described in GB, and a data warehouse's total footprint measured in PB are all the same kind of number at wildly different scales, and converting between them by hand means multiplying or dividing by 1,024 or 1,000 several times over depending on which base a specific provider actually uses. This tool converts between bytes, KB, MB, GB, TB, and PB using either binary or decimal base, built for the scale of enterprise storage and cloud billing rather than just a single file's size.

Quick answers for Data Size Converter

Does it use binary (1024) or decimal (1000) unit sizes?
Binary only, every unit step multiplies by 1024 (1 KB = 1024 bytes). There is no toggle for decimal, 1000-based units.
What units can I convert between?
Bytes, KB, MB, GB, TB, and PB, entering a value in any one of them shows the equivalent in all six at once.
Does it round very large or small results?
Results are shown with up to 6 decimal places, and values that would round to an unreadable near-zero number are hidden from the results list.
