Why this conversion matters in chemistry

Targeted-proteomics serial dilutions is a place this matters. A 1 pmol/µL stock diluted 100-fold gives 10 fmol/µL — the working concentration for an LC-MS/MS sensitivity check or for spiking an isotope-labeled internal standard into a limited-sample cohort. The same dilution pattern bridges new and outgoing internal-standard lots without re-anchoring the entire calibration curve. Carryover between calibration lots remains the main source of systematic bias in these bridging studies. That 1000 fmol per pmol is the pico and femto prefix step, no more.

Formula

fmol = pmol × 1000

Worked Examples

1 pmol = 1000 fmol

The conversion anchor — the pico to femto prefix step.

0.1 pmol = 100 fmol

About a sub-picomole working amount on a sensitivity-check injection.

0.001 pmol = 1 fmol

1 fmol — about a typical LC-MS/MS detection floor.

10 pmol = 10000 fmol

10 pmol — about a typical ELISA-assay reagent amount.

Frequently Asked Questions

How do I convert pmol to fmol?
Multiply by 1000. So 5 pmol becomes 5000 fmol. The relationship is exact through the pico and femto prefix step.
Why convert pmol to fmol?
Many analytical instruments and trace-detection assays report in femtomoles for cleaner numerical resolution at very low concentrations. The pmol form is the upstream working stock; the fmol form is the downstream injection.
How do pmol and fmol relate to moles?
1 pmol = 10⁻¹² mol = 1000 fmol. 1 fmol = 10⁻¹⁵ mol. Each prefix step scales by 1000 — three orders of magnitude top to bottom of the chain.
