About EasyUnitTools

The Unit Converter is the heart of the site: 25+ categories of measurement built on a single, carefully verified conversion engine with exact international constants, unit search, swap, copy and precision controls.

Around it sits a growing set of calculators and tools for the things people do every day — splitting a bill, scaling a recipe, working out a discount, or comparing time zones.

Privacy first

There is no database, no analytics on your inputs, and no server-side storage. Favourites and recent conversions are kept only in your own browser's local storage and can be cleared at any time.

Accuracy

Conversion factors are defined from internationally agreed definitions and covered by an automated regression suite that checks every unit pair, in both directions, on every change.
