This app is only available on the App Store for iOS devices.


The most extensive and easy to use unit conversion utility ever available for a mobile device, even for a desktop computer. It is an absolute world record !!!!. More than 3,900 units grouped in 74 categories including more than 70 universal and atomic constants. This made possible to do more than 1,900,000 direct conversions and more than 900 millions with prefix.

Simply select one of the 74 categories, use the keyboard to type the value you want to convert, select the input and output units and prefix values and touch the convert button. it's that simple.

The iPhone & iPod touch version include the following features :
· Each unit has a short description.
· Select Favorites units of common use in a separate User's units database.
· Selectable database to use, the default complete one or the User's favorite units database.
· Build a table with all the available conversions within any selected category.
· Automatic conversion of every unit to the S.I. system.

Customer Reviews

Too much clutter.

It's got a LOT of units to convert, I'll give it that... but thats it. Look elsewhere if you expect to convert even simple units within a reasonable time (or patience).

A layered GUI would have done this app a great justice, along with field or cursor feedback so I know where I'm typing. A back, or cancel button would have been a nice touch, too.

The app sticks or hangs a lot when you try to toggle back to the unit selection. Buttons are tiny and ill-placed. It places no cursor, tint or other visual cue to indicate WHAT field you're typing into. Audio feedback reminds me of early ms-dos for some reason, or when you reset your PRAM for the Mac users here.

So if you get your kicks in life by converting to obscure measurement systems - go for it. If you need to actually get some work done - look elsewhere.


By far the most comprehensive converter! Thanks and great job, well worth it!!!
