This little convertor is easy to use and effective. Nothing fancy here, choose your units, enter a value and the conversion automatically appears! There are a ton of conversions that you'll appreciate - as you can see in the graphic below, now I know that my keg of Kahlua is going to serve a lot of shots!

This little convertor will likely do the trick for you... but there are a few conversions missing. For instance, I need to convert "milliGauss" to "microteslas" for magnetism in physics class... but convert won't do it for me.

Another missing feature is the ability to save frequently done conversions. I'd really like to see 5 user configurable buttons that I could press to have my 5 most used conversions pop up in the window any time I want them. Still, for what Convert does it's great value.
