pmol/L to nmol/L Converter
To convert pmol/L to nmol/L, divide the value in picomoles per liter by 1,000.
How to Convert pmol/L to nmol/L
This pmol/L to nmol/L converter changes picomoles per liter into nanomoles per liter. Enter pmol/L and get nmol/L.
There are 1,000 picomoles in one nanomole, and the liter stays the same. Divide by 1,000.
For example, 850 pmol/L ÷ 1,000 = 0.85 nmol/L.
1 pmol/L = 0.001 nmol/LDivide the value in pmol/L by 1,000 to get nmol/L.Conversion Formula
The formula to convert pmol/L to nmol/L is:
Where:
- pmol/L = concentration in picomoles per liter
- nmol/L = concentration in nanomoles per liter

Worked Examples
Here are some common examples of pmol/L to nmol/L conversion:
- 0.001 nmol/L = 1 pmol/L
- 0.005 nmol/L = 5 pmol/L
- 0.033 nmol/L = 33 pmol/L
- 0.1 nmol/L = 100 pmol/L
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 nanomoles per liter (nmol/L)?
Nanomoles per liter (nmol/L) is a unit of molar concentration. It tells you how many nanomoles of a substance are present in one liter of liquid.
It is also written as nM (nanomolar). 1 nmol/L = 10−9 mol/L.
Why Is the Conversion Factor 0.001?
Both units are “per liter”, so the volume part is the same. Only the amount part changes. Picomole is 10⁻¹² mole, while nanomole is 10⁻⁹ mole.
Therefore, 1 picomole per liter equals 0.001 nanomoles per liter. To convert pmol/L to nmol/L, you divide by 1,000, and to convert nmol/L to pmol/L, you multiply by 1,000.
Uses and Importance of pmol/L and nmol/L
This conversion is common when two labs report the same hormone in different molar units.
Comparing lab results
If an older report shows 1,200 pmol/L and a new one shows 1.2 nmol/L, the two values are the same.
Research tables
Tables that mostly use nM can include pM values after conversion.
Sequencer loading
Loading concentrations in pM can be compared with library stocks in nM.
Frequently Asked Questions (FAQ)
What is 1 pmol/L in nmol/L?
1 pmol/L = 0.001 nmol/L.
What is 1,500 pM in nM?
1,500 ÷ 1,000 = 1.5 nM.
Which unit should I use?
Use the one that gives a readable number, and always use the same unit as your reference range.
Is pmol/L smaller than nmol/L?
Yes. 1 pmol/L is one thousandth of 1 nmol/L.
Does this depend on the hormone or molecule?
No. The factor is always 1,000.
