mmol to ng Converter
To convert mmol to ng, multiply the value in millimoles by the molecular weight (g/mol), then multiply by 1,000,000.
How to Convert mmol to ng
Use this mmol to ng converter to change millimoles into nanograms. Enter mmol and the molecular weight.
mmol × MW gives milligrams. One milligram is 1,000,000 nanograms, so ng = mmol × MW × 1,000,000.
For example, 0.0001 mmol of creatinine (MW 113.12 g/mol) is 0.0001 × 113.12 × 1,000,000 = 11,312 ng.
ng = mmol × MW × 1,000,000Multiply the millimoles by the molecular weight (g/mol), then multiply by 1,000,000 to get nanograms.Conversion Formula
The formula to convert mmol to ng is:
Where:
- mmol = amount in millimoles (10⁻³ mol)
- ng = mass in nanograms (10⁻⁹ g)
- MW = molecular weight (molar mass) in g/mol

Worked Examples
Here are some common examples of mmol to ng conversion, using creatinine (MW 113.12 g/mol):
- 113,120,000 ng = 1 mmol
- 565,600,000 ng = 5 mmol
- 3,732,960,000 ng = 33 mmol
- 11,312,000,000 ng = 100 mmol
Unit Definitions
What is a millimole (mmol)?
A millimole (mmol) is a unit of amount of substance equal to 10⁻³ mole.
The prefix milli- (m) means 10⁻³, or one thousandth. So 1 mmol = 0.001 mol.
What is a nanogram (ng)?
A nanogram (ng) is a unit of mass equal to 10⁻⁹ gram.
The prefix nano- (n) means 10⁻⁹, or one billionth. So 1 ng = 0.000000001 g.
Why Is Molecular Weight Needed?
Moles count particles. Grams measure mass. One particle of each substance has its own mass, so the link between them is the molecular weight (MW), also called molar mass.
MW tells you how many grams one mole of a substance weighs. For example, one mole of water weighs about 18.015 g, while one mole of glucose weighs about 180.16 g.
Therefore, to convert mmol to ng, you multiply by MW, then multiply by 1,000,000. The extra step (× 1,000,000) only adjusts for the different sizes of the two units.
Uses and Importance of mmol and ng
This is a big jump in scale. It is used when a stock prepared in millimoles must be expressed as the tiny masses used in sensitive tests.
Calibrators for LC-MS
Calibrators are often spiked in nanograms, while the stock is calculated in mmol.
Creatinine chemistry
Creatinine is a small molecule measured in many clinical labs; its molecular weight links molar and mass units.
Dilution planning
Knowing the nanogram mass in a millimole helps plan the dilution steps to reach a working standard.
Frequently Asked Questions (FAQ)
How many ng are in 1 mmol of creatinine?
1 × 113.12 × 1,000,000 = 113,120,000 ng, which is about 113 mg.
What is creatinine's molecular weight?
Creatinine is C₄H₇N₃O, about 113.12 g/mol with standard atomic weights.
Why a million?
mmol × MW gives mg. There are 1,000 µg in 1 mg and 1,000 ng in 1 µg, so 1 mg = 1,000,000 ng.
Does this relate to the creatinine lab factor 88.4?
Yes. Labcorp converts creatinine from mg/dL to µmol/L with a factor of 88.4. That number comes from 10,000 ÷ 113.12.
Can I use this page for blood creatinine results?
This page converts amounts, not concentrations. Use a concentration converter and your lab's reference range for blood results.
