45 |
In order to collect various unit conversions into one central |
|
46 |
manageable (and especially: browsable) place, all previously |
|
| 564 | 47 |
spread knowledge about metric (and other) conversions has been |
| 363 | 48 |
brought into this class. |
49 |
||
50 |
This class is purely functional, abstract and has no instances; |
|
51 |
all queries are via class protocol. |
|
52 |
Choosing the Magnitudes category as its home is arbitrary. |
|
53 |
||
| 515 | 54 |
The supported units are setup in the classes initialize method; |
| 364 | 55 |
supported are: |
| 886 | 56 |
meter - inch - feet - foot - yard |
57 |
meter2 - acre - 'german-ar' 'german-hektar' are |
|
58 |
liter - gallon - barrel - floz |
|
59 |
celsius - fahrenheit |
|
| 364 | 60 |
and many others. |
61 |
||
| 515 | 62 |
The converter does a recursive search for a conversion; |
63 |
thus, if there is a conversion from #inch to #millimeter and another |
|
64 |
from #millimeter to #kilometer, conversion from #inch to #kilometer |
|
65 |
is found automatically. |
|
66 |
||
| 886 | 67 |
No Warranty: |
68 |
The numbers and conversion factors were obtained from the Unix |
|
69 |
units command. Please check before using it - there might be |
|
70 |
typos or wrong conversions in the setup code. |

Notice: |
74 |
This class is *much* older than the younger and more object oriented |
|
75 |
Measurements package. Other than solving similar problems, these two packages |
|
76 |
are not related. |
