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,
themes. You can add, modify, hide or delete them. All configuration
are stored in flat files. Since the format of the output can be
configured, data exchange with other software
