Inline and reversible
Enter a value, see the result instantly, and swap from/to units without leaving the conversion surface.
iPhone + iPad Instant conversion
The unit you have. The unit you need.
Easy Unit keeps everyday conversion inline, immediate, and reversible—with favorites one tap away and a Toolkit for seeing one value in many units at once.

No conversion maze
Common math should not require navigation.
Easy Unit keeps the converter visible, the direction obvious, and the result stable while you type.
Favorites stay close
Mark the pairs you use most and find them at the top of Units every time you return.
One input, many answers
Toolkit converts a selected source unit into every relevant unit in its category at once.
One catalog
Every surface agrees
The home converter, searchable Units list, favorites, and Toolkit all derive their supported values from one deterministic conversion catalog.
