nmol to pg Converter
To convert nmol to pg, multiply the value in nanomoles by the molecular weight (g/mol), then multiply by 1,000.
How to Convert nmol to pg
Use this nmol to pg converter to change nanomoles into picograms. Enter nmol and the molecular weight.
nmol × MW gives nanograms. Multiply by 1,000 to get picograms: pg = nmol × MW × 1,000.
For example, 0.5 nmol of estradiol (MW 272.388 g/mol) is 0.5 × 272.388 × 1,000 = 136,194 pg.
pg = nmol × MW × 1,000Multiply the nanomoles by the molecular weight (g/mol), then multiply by 1,000 to get picograms.Conversion Formula
The formula to convert nmol to pg is:
Where:
- nmol = amount in nanomoles (10⁻⁹ mol)
- pg = mass in picograms (10⁻¹² g)
- MW = molecular weight (molar mass) in g/mol

Unit Definitions
What is a nanomole (nmol)?
A nanomole (nmol) is a unit of amount of substance equal to 10⁻⁹ mole.
The prefix nano- (n) means 10⁻⁹, or one billionth. So 1 nmol = 0.000000001 mol.
What is a picogram (pg)?
A picogram (pg) is a unit of mass equal to 10⁻¹² gram.
The prefix pico- (p) means 10⁻¹², or one trillionth. So 1 pg = 0.000000000001 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 nmol to pg, you multiply by MW, then multiply by 1,000. The extra step (× 1,000) only adjusts for the different sizes of the two units.
Uses and Importance of nmol and pg
Picograms and nanomoles meet in low-level hormone testing, especially for estrogens.
Estrogen assays
Estradiol is reported in pg/mL or pmol/L. Converting nmol to pg helps prepare calibrators.
Stock dilutions
A stock of a few nmol is diluted to give picogram standards.
Research reporting
Some studies use molar units and others mass units; conversion links them.
Frequently Asked Questions (FAQ)
How many pg are in 1 nmol of estradiol?
1 × 272.388 × 1,000 = 272,388 pg.
What does the × 1,000 step do?
nmol × MW gives ng, and 1 ng = 1,000 pg.
How do I go from pmol/L to pg/mL for estradiol?
Divide by about 3.67 (1,000 ÷ 272.388). Labcorp lists 3.67 for the reverse direction, pg/mL to pmol/L.
Is estradiol the same as estrogen?
Estradiol is the main estrogen in the body, but estrone and estriol are also estrogens with their own molecular weights.
Does this interpret estrogen levels?
No. It converts units only.
