Frequently asked questions
How accurate are the conversions?
Conversions use exact, standard conversion factors defined by the NIST and ISO. Results are precise to 10 significant digits.
Why are there different values for data sizes?
Data size units can be decimal (1 KB = 1000 bytes, SI standard) or binary (1 KiB = 1024 bytes, IEC standard). We show both.
Is my data sent anywhere?
No. All conversion math runs in your browser.
