Yea, because it is well known that they correlate, like C and F.
The loads idea requires people to actually know what the ratio is for mapping
and the data user to be able to show the correct unit for the user. Also, the
load might vary a bit and not line up cleanly, so it might display a 1.2 load
washer or something.
I don't think the variation would worry most people ...it is just an indication
of how much maybe put into the machine.
Not many people measure their load into the machine.:-)
Maybe it is best to have a single unit (kg?) and have the data provider
translate the information into loads, but it seems that mapping a million
washing machines that are all labeled in one unit for one continent in its
native unit is good for mappers to get it mapped correctly.
The mappers need to be able to enter the data they have directly, in what ever
units they have, this minimises any possibility of input error.
Any calculation should be done by the data user .. into whatever units they
desire.
Correlation between the units should not be handled by 1,000,002 mappers ..
they may have different ideas of the correlation.
This helps in that there is only one area of calculation .. and that can be
easily corrected if required.
Where no conversion is needed, say cu ft to cu ft, then there will be no
calculation .. and this would probably be the case for a local map.
