No, for kilo the original Unit would be gram, original Unit Prefix "k" kilo. But yes, if we rather want to give each combination of SI prefix and unit a wikidata page, we could do that. > JMc: May be more efficient to store not reconstruct the original value.

Happily.

As said above, this implies that all combinations of units and SI prefixes get their own Wikidata item. This is possible to create and could even reflect some of the knowledge about applicable prefixes. Only drawback is that for the normalizedMeasurement fractionDigits is redundant, it will always be totalDigits minus 1, since normalized. But that is a small price for a nicer model.
