Free Data Storage Converter
Convert bits, bytes, kilobytes, megabytes, gigabytes and binary units.
What is the Data Storage Converter?
Convert bits, bytes, kilobytes, megabytes, gigabytes and binary units.
Pick a value and units and see the converted size immediately. It treats 1 byte as 8 bits, decimal units as powers of 1000 and binary units such as KiB and MiB as powers of 1024.
Quick, reliable engineering arithmetic saves time on site and in the workshop. These tools show their working so you can check the result.

Step 1
Enter your values, choosing the units you are working in.
Step 2
Read the result and the supporting numbers shown beneath it.
Step 3
Check the result against a second method or a reference table before you rely on it.
Tips for better results
Operating systems and drive makers sometimes use different conventions, which is why a drive can appear smaller than advertised.
Keep units consistent from start to finish.
These tools are for estimates. Safety critical designs need a qualified engineer.
Privacy and where your data goes
Everything you type into the data storage converter stays on your own device. Zapxa does not receive your numbers or documents. If you clear your browser data, your saved entries will be removed, so download a PDF of anything you want to keep.
Frequently asked questions
Is a kilobyte 1000 or 1024 bytes?
In SI usage a kilobyte is 1000 bytes, while 1024 bytes is a kibibyte (KiB).
How many bits are in a byte?
Eight bits.
Is the data storage converter free?
Yes. It is free to use with no signup, no watermark and no usage limits.
