About Us

Unit.Converter is a free online unit converter covering length, weight, volume, temperature, area, and dozens of other measurement categories — from everyday conversions like kilometers to miles, to specialized ones used in engineering, science, and international trade.

Who runs this site

Unit.Converter is run by Adam Sam (CEO), with the site actively developed and maintained on an ongoing basis — new converters, corrections, and improvements ship regularly, not as a one-time launch left untouched. Questions, corrections, or feedback are welcome at unitconverta@gmail.com — see the Contact section of the Privacy Policy for the same address.

What we offer

Every converter on this site does the calculation instantly in your browser — no page reloads, no account needed. Alongside the calculator, most pages include a conversion table, the underlying formula, and a plain-English explanation of the units involved, so you can double-check the math or learn a bit about where a unit comes from.

Accuracy

Conversion factors are based on standard, published definitions for each unit — primarily the SI brochure published by the International Bureau of Weights and Measures (BIPM), and the reference conversion tables published by the US National Institute of Standards and Technology (NIST). If you ever spot a figure that looks off, we'd rather know about it than have it sit there wrong — see the contact email above.

Currency rates

Unlike the fixed physical conversions elsewhere on the site, our currency converter pulls live exchange rates from a third-party rate provider each time the page loads, since those change constantly.
