About Us

Unit.tech 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.

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. If you ever spot a figure that looks off, we'd rather know about it than have it sit there wrong.

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.
