Is it free and private?
Yes, free and fully offline in your browser.
What can I convert?
Length, weight, temperature, area, volume, speed, time, digital storage, pressure, energy and angle.
Does it work offline?
Yes — all the conversion factors are built in, so no server is needed.
Why is there no currency conversion?
Currency needs live exchange rates from a server; this tool stays 100% local, so it's left out.
How accurate is it?
It uses standard conversion factors at full floating-point precision, rounded only for display.
Can it convert temperatures correctly?
Yes — Celsius, Fahrenheit and Kelvin using the proper offset formulas, not just a multiplier.
