Answer:
1000 times
Step-by-step explanation:
In the metric system, "nano" represents a magnitud measured in the by [tex]10^{-9}[/tex] scale, while "pico" represents [tex]10^{-12}[/tex].
If you divide a nanogram by a picogram you will see that one nanogram is actually 1000 picograms, therefore a scale capable of measuring a picogram is 1000 times more capable than another that measures up to the nanogram.
