Why this conversion matters in chemistry
LC-MS/MS method-development serial dilutions is a worked example. A 1 nmol peptide standard reconstituted in 1 mL gives 1 µM, equivalently 1000 fmol/µL. Further serial dilution to 10 fmol/µL puts the final injection right at the sensitivity floor of most modern triple-quadrupole instruments. Where the 10⁶ fmol per nmol comes from: two SI prefix steps (nmol → pmol → fmol). The conversion just bridges nmol-scale standard preparation and fmol-scale assay-window planning.
Formula
fmol = nmol × 10⁶
Worked Examples
1 nmol = 1000000 fmol
The conversion anchor — six prefix decades, the full span of the relationship.
0.001 nmol = 1000 fmol
1 pmol — the bridge step between nmol stock and trace assays.
0.000001 nmol = 1 fmol
1 fmol — about a typical LC-MS/MS detection limit.
10 nmol = 10000000 fmol
10 nmol — about a typical small-scale standards preparation.
Frequently Asked Questions
How do I convert nmol to fmol?
Multiply by 10⁶ (one million). So 1 nmol becomes 10⁶ fmol. The relationship is exact through two SI prefix steps.
Why is the factor so large?
The fmol (10⁻¹⁵) and nmol (10⁻⁹) prefixes span six orders of magnitude — through the intermediate pmol step. Two prefix decades each between adjacent units, twice.
When is this useful?
Calculating how much of a nmol-scale standard reaches a fmol-scale detection floor in an LC-MS/MS workflow. The conversion is the routine first step in dilution-series design that bridges the two scales.
