pg/mL to pmol/L
pg/mL to pmol/L depends on the substance being measured. Here are the analytes reported in these units, each with its own factor.
There is no single number for this pair: the factor is the substance's molar mass, so it differs for every analyte. Find yours below.

Frequently asked questions
What do I multiply by to go from pg/mL to pmol/L?
It depends on what is being measured. The step from a mass unit to a molar one carries the substance's molar mass, and every substance has its own. The table above gives the factor for each.
What if my analyte is not on the list?
Then do not borrow a factor from a neighbouring row - it would be wrong by however much the two molar masses differ. Ask the laboratory that issued the result, or check the reference table linked below.
