More than an Unit Converter - a NumericalChameleon


The NumericalChameleon is free, open source, platform-independent and comprehensive software in order to convert units with a precision of up to 1000 decimal places.

It supports more than 5200 units in 93 categories, including not only all important physical units in categories like length, area, volume, electricity, magnetism, force, power, energy, pressure, mass, temperature, velocity, acceleration, radioactivity, fuel consumption, time, etc. but also useful units in non-standard categories like exchange rates, time zones, spoken numbers (literally and by audio), roman numerals, geographic coordinates, radixes, fractions, checksums, bits&bytes, screen resolutions, colorcodes, unicodes, international dial codes, calendar and holiday calculations and many more.

It can be run as portable app or as an installed app it can be run on single and multi-user environments in networks on all supported platforms (Windows, Linux, Mac OS X, Unix, etc.) locally or on the network.

It provides a dynamic, modern graphical user interface. It has been internationalized and localized in many languages. 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. Since the format of the output can be configured, data exchange with other software is easy.

The NumericalChameleon is released under the terms of GNU GPL 3 or later.
