Works great--add grains conversion?

Easy to use and works well. The only thing it lacks as far as I'm concerned is conversion from grains to other weight units--as a firearms enthusiast (and there are a lot of us out there) I do a lot of measuring in grains, and it's sometimes handy to know how that translates.

Good at its job, just needs more jobs

The app does a great job with converting units accurately. It especially shines in the data section, distinguishing between SI base 2 and base 10 prefixes. However, some units are not present, such as Rankine, Romer, Reamur, Newton, and Delisle (all temperature units, spelling maybe wrong here) and the electron volt. It also lacks currency conversions (this may be harder to implement due to daily changes), In short: the functions that it has works great, it just needs more functions.

Okay for simple use, by has some limitations

for basic conversions, this app is fine. However, it is has a lot of limitiations. No number formatting. No copying to the clipboard the results (or name of units). No search for units. No exponential/scientific notation for dealing with extremely large or small numbers. popup keyboard hides the buttons...

Functional and Easy to Use

Useful, simple, and easy-to-use converter. Very customizable, too. Highly recommended.

Just one thing

Need to have the 'swap' in the saved conversions as well. That would make the app just perfect! And if it's not already apparent, I am being spoiled. This app perfect in every other way.

Lacking currency conversion.

Simple, elegant design. The feature to save favorite conversions is nice. I have however 2 complaints: there is no option to convert currency, and there is no option to swap the units in the favorites. Update: Favorites are no longer working.

It does what it says, and it works! Plus, saving conversions is a great feature.. Never again will I have to tell Windows Calculator that no, I don't want to convert Angstroms to Angstroms, I want to do something useful.

Nice converter

Like the other reviewers said, it has a clean interface and a ton of conversion choices.

At least one error

Didn't check out all the conversions, but the first one I did was wrong. I chose data, convert from gigabytes to megabytes. It showed 150 gb was 150000 mb. The correct answer is 153600 mb. Does not inspire confidence!
