Like +many similar programs, it can handle multiplicative scale changes. It can +also handle nonlinear conversions such as Fahrenheit to Celsius or wire +gauge, and it can convert from and to sums of units, such as converting +between meters and feet plus inches. + +Beyond simple unit conversions, GNU Units can be used as a general-purpose +scientific calculator that keeps track of units in its calculations. You +can form arbitrary complex mathematical expressions of dimensions including +sums, products, quotients, powers, and even roots of dimensions. Thus you +can ensure accuracy and dimensional consistency when working with long +expressions that involve many different units that may combine in complex +ways. + +The units are defined in an external data file. You can use the extensive +data file that comes with this program, or you can provide your own data +file to suit your needs. You can also use your own data file to supplement +the standard data file.") + (license license:gpl3+) + (home-page "http://www.gnu.org/software/units/"))) |
