pmol/L to mol/L Converter
To convert pmol/L to mol/L, divide the value in picomoles per liter by 10¹².
How to Convert pmol/L to mol/L
This pmol/L to mol/L converter changes picomoles per liter into moles per liter. Enter pmol/L to see mol/L.
One picomole is 10−12 mole. The liter stays the same, so divide by 1012.
For example, 400 pmol/L ÷ 1012 = 4 × 10−10 mol/L.
1 pmol/L = 1 × 10⁻¹² mol/LDivide the value in pmol/L by 1,000,000,000,000 (10¹²) to get mol/L.Conversion Formula
The formula to convert pmol/L to mol/L is:
Where:
- pmol/L = concentration in picomoles per liter
- mol/L = concentration in moles per liter

Unit Definitions
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.
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.
Why Is the Conversion Factor 1 × 10⁻¹²?
Both units are “per liter”, so the volume part is the same. Only the amount part changes. Picomole is 10⁻¹² mole, while mole is 1 mole.
Therefore, 1 picomole per liter equals 1 × 10⁻¹² moles per liter. To convert pmol/L to mol/L, you divide by 10¹², and to convert mol/L to pmol/L, you multiply by 10¹².
Uses and Importance of pmol/L and mol/L
Converting picomolar values to mol/L is useful for modelling, for textbook formulas and for comparing with data given in M.
Pharmacology models
Receptor models often need concentrations in mol/L. Picomolar data must be converted first.
Unit checks
Converting to mol/L and back is a quick way to catch a missing power of ten.
Teaching
It shows students how tiny picomolar concentrations really are.
Frequently Asked Questions (FAQ)
What is 1 pmol/L in mol/L?
1 pmol/L = 1 × 10−12 mol/L.
What is 1 pM in M?
1 pM = 10−12 M. pM and pmol/L are the same unit.
How many molecules per liter is 1 pmol/L?
About 6.022 × 1011 molecules in every liter.
Why does my answer look like 4e-10?
Some software writes 4 × 10−10 as 4e-10. They mean the same number.
Could 1 pmol/L be written as 1e-12 M?
Yes. 1e-12 is computer shorthand for 1 × 10−12, so 1 pmol/L = 1e-12 mol/L.
