Frequently asked questions

Which units does the converter support?

It covers length, weight & mass, temperature, area, speed, volume and digital storage — including metric, US/imperial and (for data) both decimal and binary units.

Are the conversions accurate?

Yes. Conversions use exact internationally defined factors (for example, 1 inch = 0.0254 m exactly), and results are shown to 7 significant figures.

Does it work offline and keep my data private?

All conversions run in your browser with no server calls, so the tool keeps working offline once loaded and nothing you type is uploaded.
