The library provides an implementation of dimensioned values for Ada. Unit checks are made at run-time, if not optimized out by the compiler. SI and irregular measurement units are supported. Shifted units like degrees Celsius are supported too. Conversions from and back to strings are provided for all various irregular units. An extensive set of GTK widgets for dealing with dimensioned values is included, though use of GTK is not mandatory for the rest of the library.

Browser based ballistics calculator for arrows and bullets: http://www.x-ballistics.eu/app/web/ballistics/index

Java program for computations with values expressed in terms of physical or other units. Supports complicated mathematical expressions and user-defined functions. Invoked from scripts, line command, or as GUI. Extensive units data base.

Keywords: -simultaneously fit several SAXS and SANS data sets with polydisperse (Schultz-Zimm or Gaussian distribution f(R)) spherical core-shell-shell nanoparticles -analytical expressions are used for from factor F(Q) and its integral over f(R), no numerical integration required -absolute units -Mathematica is required via console (MathKernel) -Mathematica's local and global optimizers (simulated annealing, differential evolution, Nelder-Mead, ...) can be used -range for fit parameters and further constraints between fit parameters are possible -Monodisperse(!) hard sphere structure factor can be used, too -long computation times (depending on problem size and amount of constraints) from hours to a few days are possible -non-parallelized code

MNDACS (Mesh Networked Data Acquisition and Control System) is a Java, network based control system. The project approach is to build a mesh system to tolerate control unit breakdowns with load balancing between units.

Cute Converter is now part of LibreEngineering suite: http://sourceforge.net/projects/libreeng/

PyPhys is a set of physical quantity classes written in Python. The classes represent physical quantities (like length, pressure, energy, etc.) that can be assigned and extracted in many different units.

Better than NASA--avoid sending *your* Mars probe off to empty space! SafeUnits is a Java-based project providing measurement-related classes whose instances, when exported, can only be imported to classes of matching types. NASA, just a friendly jibe

A plugin for the Eclipse IDE implementing NumericalChameleon: a powerful numerical convertor, supporting more than 2300 units in 78 categories (physics, radixes, exchange rates, unicode, etc). Fully integrated in the Eclipse IDE (refactoring, copy/paste)

Esos is a GTK2-based program for converting values expressed in one unit into another. It supports conversion between multiple types of units, falling into categories such as temperature, distance, volume, mass, etc.

This Java library (currently 217 classes) is able to handle quantities in terms of basic arithmetics, conversion to similar units, serialization. As framework it allows to create new dimensions and units by inheritance.
