µmol/L to nmol/L Converter
To convert µmol/L to nmol/L, multiply the value in micromoles per liter by 1,000.
How to Convert µmol/L to nmol/L
Use this µmol/L to nmol/L converter to change micromoles per liter into nanomoles per liter. Enter µmol/L and get nmol/L.
Both units are per liter. One micromole is 1,000 nanomoles, so multiply by 1,000.
For example, 0.075 µmol/L × 1,000 = 75 nmol/L.
1 µmol/L = 1,000 nmol/LMultiply the value in µmol/L by 1,000 to get nmol/L.Conversion Formula
The formula to convert µmol/L to nmol/L is:
Where:
- µmol/L = concentration in micromoles per liter
- nmol/L = concentration in nanomoles per liter

Unit Definitions
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.
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 1,000?
Both units are “per liter”, so the volume part is the same. Only the amount part changes. Micromole is 10⁻⁶ mole, while nanomole is 10⁻⁹ mole.
Therefore, 1 micromole per liter equals 1,000 nanomoles per liter. To convert µmol/L to nmol/L, you multiply by 1,000, and to convert nmol/L to µmol/L, you divide by 1,000.
Uses and Importance of µmol/L and nmol/L
µM and nM are neighbouring units. Scientists move between them to keep numbers readable, especially in drug and hormone work.
Drug potency (IC50 values)
Potency values below 1 µM are usually written in nM. For example, 0.25 µM is written as 250 nM.
Hormone results
Some labs report steroid hormones in nmol/L. A value published in µmol/L can be converted to match.
Nucleic acid work
Oligo working solutions are often diluted from µM stocks to nM concentrations.
Frequently Asked Questions (FAQ)
How many nmol/L are in 1 µmol/L?
1 µmol/L = 1,000 nmol/L.
What is 0.5 µM in nM?
0.5 × 1,000 = 500 nM.
How do I make a 100 nM solution from a 10 µM stock?
10 µM is 10,000 nM. 10,000 ÷ 100 = 100, so dilute the stock 100-fold, for example 1 µL into 99 µL.
Is µmol/L to nmol/L the same for all substances?
Yes. Only the prefix changes.
Why do papers switch between µM and nM?
They pick the unit that avoids long decimals or very large numbers.

Accuracy and Scope
The factor 1 µmol/L = 1,000 nmol/L is exact.
It does not convert between mass and molar units.
