It's a fine question Bluthund. I also was wondering if it meant the scale itself weighed a kilo, or that it is a scale that weighs things one kilo or less. For there are scales, and then there are scales.
Kilogram is also an accepted term in swedish, correct? Otherwise how would you differentiate between all the other SI units that have the kilo- prefix. But I assume that kilogram is automatically assumed when it is just kilo by itself.
