pmol to nmol Converter
To convert pmol to nmol, divide the value in picomoles by 1,000.
How to Convert pmol to nmol
This pmol to nmol converter changes picomoles into nanomoles. Enter the value in pmol to see nmol.
There are 1,000 picomoles in one nanomole. Divide by 1,000, or move the decimal point three places to the left.
For example, 4,500 pmol ÷ 1,000 = 4.5 nmol.
1 pmol = 0.001 nmolDivide the number of picomoles by 1,000 to get nanomoles.Conversion Formula
The formula to convert pmol to nmol is:
Where:
- pmol = amount in picomoles (10⁻¹² mol)
- nmol = amount in nanomoles (10⁻⁹ mol)

Unit Definitions
What is a picomole (pmol)?
A picomole (pmol) is a unit of amount of substance equal to 10⁻¹² mole.
The prefix pico- (p) means 10⁻¹², or one trillionth. So 1 pmol = 0.000000000001 mol.
What is a nanomole (nmol)?
A nanomole (nmol) is a unit of amount of substance equal to 10⁻⁹ mole.
The prefix nano- (n) means 10⁻⁹, or one billionth. So 1 nmol = 0.000000001 mol.
Why Is the Conversion Factor 0.001?
A picomole is 10⁻¹² mole, while a nanomole is 10⁻⁹ mole.
Therefore, 1 picomole equals 0.001 nanomoles. To convert pmol to nmol, you divide by 1,000, and to convert nmol to pmol, you multiply by 1,000.
Uses and Importance of pmol and nmol
Converting picomoles to nanomoles helps you add up small reaction amounts and compare them with a stock tube labelled in nmol.
Tracking stock use
Running 400 reactions at 10 pmol each uses 4,000 pmol, which is 4 nmol of the stock.
DNA ligation
Ligation reactions are often planned in pmol or fmol of DNA ends. Converting to nmol helps when you work with larger preparations.
Reporting
Values over about 1,000 pmol usually read better in nmol.
Frequently Asked Questions (FAQ)
What is 1 pmol in nmol?
1 pmol = 0.001 nmol.
What is 100 pmol in nmol?
100 ÷ 1,000 = 0.1 nmol.
How many pmol are in a 100 µM primer stock per µL?
A 100 µM stock holds 100 pmol per µL, which equals 0.1 nmol per µL.
Is pmol smaller than nmol?
Yes. A picomole is one thousandth of a nanomole.
Does this conversion depend on DNA length?
No. It only changes the counting unit. DNA length matters only when you convert between moles and nanograms.

Accuracy and Scope
The factor 1 pmol = 0.001 nmol is exact.
To convert DNA mass (ng) into pmol, you also need the length and average mass per base pair; this page does not do that step.
