pmol to mol Converter
To convert pmol to mol, divide the value in picomoles by 10¹².
How to Convert pmol to mol
This pmol to mol converter changes picomoles into moles. Type a picomole value and read the result in moles.
One picomole is 10−12 mol. Divide the picomole value by one trillion (1012) to get moles.
For example, 500 pmol ÷ 1012 = 5 × 10−10 mol, which is 0.0000000005 mol.
1 pmol = 1 × 10⁻¹² molDivide the number of picomoles by 1,000,000,000,000 (10¹²) to get moles.Conversion Formula
The formula to convert pmol to mol is:
Where:
- pmol = amount in picomoles (10⁻¹² mol)
- mol = amount in moles

- 1 × 10⁻¹⁰ mol = 100 pmol
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 mole (mol)?
The mole (mol) is the SI base unit for amount of substance. It counts particles, such as atoms, molecules or ions.
Since 2019, one mole contains exactly 6.02214076 × 1023 particles. This number is the Avogadro constant.
Why Is the Conversion Factor 1 × 10⁻¹²?
A picomole is 10⁻¹² mole, while a mole is 1 mole.
Therefore, 1 picomole equals 1 × 10⁻¹² moles. To convert pmol to mol, you divide by 10¹², and to convert mol to pmol, you multiply by 10¹².
Uses and Importance of pmol and mol
Results in picomoles come from very sensitive methods. Converting them to moles connects them to formulas and constants that are defined per mole.
Molecule counts
Multiply the mole value by the Avogadro constant to find how many molecules are present. 1 pmol is about 6.022 × 1011 molecules.
Data reporting
Some databases store amounts in moles. Converting picomole results avoids mixing units.
Checking calculations
Converting to moles and back is a quick way to check that no power of ten was lost.
Frequently Asked Questions (FAQ)
What is 1 pmol in mol?
1 pmol = 1 × 10−12 mol, or 0.000000000001 mol.
How many molecules are in 1 pmol?
About 602 billion (6.022 × 1011) molecules.
Is it better to write the answer as a decimal or in scientific notation?
Scientific notation is safer. It is easy to lose or add a zero in a long decimal such as 0.000000000025.
Is the pmol to mol conversion exact?
Yes. It comes from the SI prefix pico-, which is defined as exactly 10−12.
Does it matter what substance I measured?
No. The factor is the same for any substance because both units count particles.
