pmol/L to µmol/L Converter
To convert pmol/L to µmol/L, divide the value in picomoles per liter by 1,000,000.
How to Convert pmol/L to µmol/L
This pmol/L to µmol/L converter changes picomoles per liter into micromoles per liter. Enter pmol/L to see µmol/L.
One micromole is 1,000,000 picomoles. The liter stays the same, so divide by 1,000,000.
For example, 350 pmol/L ÷ 1,000,000 = 0.00035 µmol/L.
1 pmol/L = 0.000001 µmol/LDivide the value in pmol/L by 1,000,000 to get µmol/L.Conversion Formula
The formula to convert pmol/L to µmol/L is:
Where:
- pmol/L = concentration in picomoles per liter
- µmol/L = concentration in micromoles 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 micromoles per liter (µmol/L)?
Micromoles per liter (µmol/L) is a unit of molar concentration. It tells you how many micromoles of a substance are present in one liter of liquid.
It is also written as µM (micromolar). 1 µmol/L = 0.000001 mol/L.
Why Is the Conversion Factor 0.000001?
Both units are “per liter”, so the volume part is the same. Only the amount part changes. Picomole is 10⁻¹² mole, while micromole is 10⁻⁶ mole.
Therefore, 1 picomole per liter equals 0.000001 micromoles per liter. To convert pmol/L to µmol/L, you divide by 1,000,000, and to convert µmol/L to pmol/L, you multiply by 1,000,000.
Uses and Importance of pmol/L and µmol/L
Converting picomolar values up to µmol/L is useful when comparing them with drug or metabolite levels reported in µM.
Comparing potencies
A binder at 500 pM is 0.0005 µM. Converting shows how it compares with a drug that works at 1 µM.
Combining data
When most values in a table are in µM, converting pM entries keeps the table consistent.
Checking reports
Converting helps confirm that a result was not typed in the wrong unit.
Frequently Asked Questions (FAQ)
What is 1 pmol/L in µmol/L?
1 pmol/L = 0.000001 µmol/L.
What is 2,000,000 pM in µM?
2,000,000 ÷ 1,000,000 = 2 µM.
Why are my results tiny decimals?
A micromole is a million times larger than a picomole.
Is pmol/L the same as pM?
Yes. pM is the short form.
Where do the pM and µM symbols come from?
They are SI prefixes (pico- and micro-) placed in front of M, the short symbol for mol/L.
