pmol to µmol Converter
To convert pmol to µmol, divide the value in picomoles by 1,000,000.
How to Convert pmol to µmol
This pmol to µmol converter turns picomoles into micromoles. Enter the picomole value to see micromoles.
One micromole is one million picomoles. Divide by 1,000,000, or move the decimal point six places to the left.
For example, 80,000 pmol ÷ 1,000,000 = 0.08 µmol.
1 pmol = 0.000001 µmolDivide the number of picomoles by 1,000,000 to get micromoles.Conversion Formula
The formula to convert pmol to µmol is:
Where:
- pmol = amount in picomoles (10⁻¹² mol)
- µmol = amount in micromoles (10⁻⁶ 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 micromole (µmol)?
A micromole (µmol) is a unit of amount of substance equal to 10⁻⁶ mole.
The prefix micro- (µ) means 10⁻⁶, or one millionth. So 1 µmol = 0.000001 mol.
It is often typed as “umol” when the µ symbol is not available.
Why Is the Conversion Factor 0.000001?
A picomole is 10⁻¹² mole, while a micromole is 10⁻⁶ mole.
Therefore, 1 picomole equals 0.000001 micromoles. To convert pmol to µmol, you divide by 1,000,000, and to convert µmol to pmol, you multiply by 1,000,000.
Uses and Importance of pmol and µmol
Converting picomoles up to micromoles helps when you sum many small uses or compare them with a stock label.
Stock management
If each reaction uses 10 pmol of a primer, 10,000 reactions use 100,000 pmol, which is 0.1 µmol.
Comparing with enzyme units
Enzyme activity is defined in µmol per minute, so small product amounts are sometimes scaled up to µmol.
Reading supplier data
Some suppliers state amounts in µmol, while assays report pmol. Converting keeps both sides equal.
Frequently Asked Questions (FAQ)
What is 1 pmol in µmol?
1 pmol = 0.000001 µmol.
What is 250,000 pmol in µmol?
250,000 ÷ 1,000,000 = 0.25 µmol.
How many picomoles make one micromole?
One million picomoles make one micromole.
Is pmol smaller than µmol?
Yes. A picomole is one million times smaller than a micromole.
Can I use this for concentrations like pmol/L?
No. pmol/L is a concentration. Use the molar concentration converters for per-liter units.
