Alternative units of measure are inconsistent; correct the values

What causes this issue?

The conversion factors you have entered for the alternative units of
measure
either do not correspond to the values in the units of measurement
table (example 1)
or are inconsistent (example 2)


&BEISPIEL& 1
You choose <LS>g</> as the base unit of measure and <LS>kg</> as the
alternative unit of measure. According to the units of measurement
table, 1,000 g = 1 kg. If you enter 900 g = 1 kg, your entry will not
correspond to the table.


&BEISPIEL& 2
You choose <LS>PC</> as the base unit of measure, <LS>kg</> as the
first alternative unit of measure, and <LS>g</> as the second
alternative unit. According to the units of measurement table, 1 kg =
1,000 g. You enter 2 pc = 1 kg, and 2 pc = 900 g. However, the units of
measurement table and your first entry both define that 2 pc = 1,000 g.
