General frequently asked questions
How accurate are the conversions on this site?
Priority calculators use standard conversion factors and show formulas, examples, common mistakes, and last-updated notes. For official engineering, medical, legal, or passport requirements, verify with the official standard.
Do you store the numbers I input?
No. Calculator values are processed in your browser where possible and are not sent to our server by the page scripts.
Why are there image size and AI token converters?
Modern conversion needs go beyond traditional units. Image DPI, print size, AI token estimates, and download speed are common workflow conversions with real user demand.
