I would like to contribute the units program bsiuntis.mac.
The name stands for basic SI units.
- In this program, like in the commercial macsyma units program,
multiplication adjoins units, physical constants, or prefixes to an expression.
- The program has an inline temperature conversion function.
- The program has display functions to readily list the known unit
conversion factors, the known physical constants, the prefixes, and examples.
- There is functions to assert new base units between mks, and cgs
- The program is named basic because it only knows a core consisting of 70 unit
conversion factors, and 27 physical constant. This is number is sufficient
for many engineering and education problems involving units.
For those problems, for which suitable units and constants are not already known;
Adding new unit conversion factors or physical constants is straight forward.
The 2 step instructions are found in the program script comments.
Regards
EAR
