Very good

How many yards are there in a kilometer? How do you say five hundred in Roman numbers? Is it cold at 40º Fahrenheit?

You can now easily answer all these questions with Numerical Chameleon, a unit conversion tool with support for more than 3,000 different units in 82 different categories. The program is coded in Java works in a very simple way: you only need to select the source and target units and see the result in real time. There's also the possibility to add results to a text list that you can later on export to a file.

Numerical Chameleon includes other original tools, such as a phonetic alphabet converter (which translates any word into the "alfa-bravo-charlie" alphabet and other similar codes) and a color picker. Ok, this one is not that original but in any case you wouldn't expect to find it in a unit converter, would you?

The only drawback I found is that apparently, you can't add new categories to the program. But then again, it's not that bad, as Numerical Chameleon is quite complete and will probably have response for all your converting needs.

Numerical Chameleon is a full featured unit conversion tool with which you'll never be lost with strange measurements ever again.

The NumericalChameleon is a free, open source, platform-independent and localized software to convert units. It converts numbers with a precision of up to 1000 significant figures. It supports more than 3200 units in 82 categories, including not only all important physical units of categories like length, area, volume, electricity, magnetism, force, power, energy, pressure, mass, temperature, velocity, acceleration, radioactivity and time, but also exchange rates, timezones, spoken numbers (literally and by audio*), roman numbers, 35 radixes, bits&bytes, screen resolutions, colorcodes, unicodes, international dial codes, calendar and holiday calculations, phonetic alphabets and more. It provides a modern, dynamic and graphical user interface.

You have unlimited access on all categories, units, icons, filters and themes. You can add, modify, hide or delete them. All configuration data are stored in flat files. You can update exchange rates from several webservices.
