* This is a file defining the conversion factors ASCEND will recognize when |
| 42 |
* it sees them as {units). Note that the assignment x:= 0.5 {100};; yields |
| 43 |
* x == 50, and that there are no 'offset conversions,' e.g. F=9/5C+32; |
| 44 |
* Added money which isn't really time 3-94 BAA |
| 45 |
* Expanded, including some of Karl's units, constants. 4-94 BAA |
| 46 |
* Updated with supplementary SI dimensions and less ambiguous mole dim. jz/baa |
