From these presentations some general analogies between these systems and their quantities can be found. There are seven preselected systems: electric, magnetic, rotation, linear motion, surface motion, hydraulic/accoustic and thermal system. Different units for current and for potential can be entered and in this way other looks on these systems can be selected. A comprehensive table of physical symbols, quantities and units is included. |

| **setcust2.zip** | 1k | 05-10-21 | | **Custom Units** Here is a program I made when those units not in the built-in Units programs were missing. For example, in the Acceleration category, they didn't add units like (_m/(_s²)) or a Pressure unit named kilopascal (_kPa). Feel free to modify the program in any way you like. If you have problems, comments, or bugs, e-mail me. Enjoy P.S. I don't know how to change the picture file from BMP format to GIF format, so I apologize for that! By the way, I deleted the "L.A." part because that's part of a class I'm taking throughout the semester, but if you want it, e-mail me for those of you taking Linear Algebra class; however you don't need it if you're not taking the class. |

| **t89v1.5.zip** | 2k | 04-10-10 | | **T89 MULTICONVERTER v1.5** T89 MULTICONVERTER Version 1.5 I mainly suppose that i had to make this program since to convert temperatures from one unit to multiple others and pressures wouldn't be nice using the calc built-in translator. The program is far simple! Just copy t89.89p, pres.89p, temp.89p, ene.89p, vesp.89p to your calc and then launch t89() select an option and enjoy! I hope my next upgrade will be done for the humidity tables Andres Valencia M valenceicq@hotmail.com |
