Select the equality for picograms and grams.

1g = 10 ^ 12 pg
1pg = 10 ^ 12 g
1g = 10 ^ 9 pg
1g = 10 ^ - 12 pg

1g = 10 ^ 12 pg

The equality for picograms and grams is:

1g = 10^9 pg

The correct equality for picograms (pg) and grams (g) is 1g = 10^12 pg. This means that one gram is equal to 10^12 picograms.
