mol/L to pmol/L Converter
To convert mol/L to pmol/L, multiply the value in moles per liter by 10¹².
How to Convert mol/L to pmol/L
Use this mol/L to pmol/L converter to express a concentration in picomoles per liter. Enter mol/L and get pmol/L.
The liter stays the same. Only the amount changes: 1 mol = 1012 pmol. Multiply by one trillion.
For example, 1.5 × 10−11 mol/L × 1012 = 15 pmol/L.
1 mol/L = 1 × 10¹² pmol/LMultiply the value in mol/L by 1,000,000,000,000 (10¹²) to get pmol/L.Conversion Formula
The formula to convert mol/L to pmol/L is:
Where:
- mol/L = concentration in moles per liter
- pmol/L = concentration in picomoles per liter

Unit Definitions
What is moles per liter (mol/L)?
Moles per liter (mol/L) is a unit of molar concentration. It tells you how many moles of a substance are present in one liter of liquid.
It is also written as M (molar). A 1 M solution has 1 mole of solute in 1 liter of solution.
What is picomoles per liter (pmol/L)?
Picomoles per liter (pmol/L) is a unit of molar concentration. It tells you how many picomoles of a substance are present in one liter of liquid.
It is also written as pM (picomolar). 1 pmol/L = 10−12 mol/L.
Why Is the Conversion Factor 1 × 10¹²?
Both units are “per liter”, so the volume part is the same. Only the amount part changes. Mole is 1 mole, while picomole is 10⁻¹² mole.
Therefore, 1 mole per liter equals 1 × 10¹² picomoles per liter. To convert mol/L to pmol/L, you multiply by 10¹², and to convert pmol/L to mol/L, you divide by 10¹².
Uses and Importance of mol/L and pmol/L
Picomolar concentrations are extremely low. They are typical for some hormones and for very potent biological molecules.
Thyroid and hormone tests
In SI units, free T4 and estradiol are reported in pmol/L.
Vitamin B12
Serum vitamin B12 is reported in pmol/L in SI units.
Potent signalling molecules
Some receptors respond to their signals at picomolar concentrations, so research data is often given in pM.
Frequently Asked Questions (FAQ)
How many pmol/L are in 1 mol/L?
1 mol/L = 1012 pmol/L, which is one trillion.
What does pM mean?
pM (picomolar) is the short form of pmol/L.
How do I convert with powers of ten?
Add 12 to the exponent. 3 × 10−11 mol/L becomes 3 × 101 pmol/L, which is 30 pmol/L.
Why are hormones measured in pmol/L?
Some hormones circulate in very small amounts. Picomoles per liter give whole numbers that are easy to read.
Does this page convert pg/mL to pmol/L?
No. That needs the molecular weight of the hormone. This page only changes molar prefixes.
