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.:-)

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.
