How to Use the Data Storage Converter

Enter a data storage value and select its current unit — the converter instantly shows the equivalent in bits, bytes, KB, MB, GB, and TB, and if the tool supports both conventions, it can show results using either the decimal (1000-based) or binary (1024-based) definition.

The Data Storage Converter handles the full range of common storage units — here's what to enter.

Entering a value and unit

Enter a data amount and select its current unit — the tool converts it instantly to every other supported unit, handling the bit-to-byte factor of 8 and the larger unit conversions automatically.

Choosing between decimal and binary interpretation

If the tool offers a choice between decimal and binary unit definitions (as covered in the decimal-vs-binary guide), selecting the one matching the context — decimal for manufacturer-advertised capacity, binary for what an operating system typically reports — gives a result that matches what's actually being compared against.

Frequently asked questions

Which convention should I use to check if my hard drive is 'really' the advertised size?

Converting the manufacturer's decimal-based advertised capacity to binary units and comparing that to what your operating system reports (which uses binary units) shows that the drive does, in fact, contain the advertised amount of storage — the discrepancy is purely a labeling convention difference, not missing capacity.

Does internet speed use the same storage units as file size?

No — as covered in the bits-vs-bytes guide, internet speed is conventionally measured in bits per second, while file size is conventionally measured in bytes; dividing an advertised speed in Mbps by 8 gives an approximate download rate in MB per second.
