About Converting Picomoles to Femtomoles
Picomole and Femtomole both measure mass concentration — how much of a substance is dissolved or dispersed in a given volume — a core calculation for preparing lab solutions, checking water quality against a regulatory limit, or formulating a pharmaceutical dose. Specifically: Picomole is 1e-12 mole units, and femtomole is 1e-15 mole units.
Formula
femtomoles = picomoles × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 picomole equals 1e-12 base units, and 1 femtomole equals 1e-15 base units, so dividing one by the other gives the direct picomole-to-femtomole factor of 1000.
Simple example
1 pmol × 1000 = 1,000 fmol
1 picomole = 1,000 femtomoles.
Real-world example
100 pmol × 1000 = 100,000 fmol
100 picomoles = 100,000 femtomoles.

Frequently asked questions
How many femtomoles are in 1 picomole?
1 picomole equals 1,000 femtomoles, using the exact defined conversion factor rather than an estimate.
How do I convert picomole to femtomole?
Multiply the picomole value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert femtomole back to picomole?
Use the reverse factor: 1 femtomole equals 0.001 picomoles. You can also use the swap control in the converter above to flip the direction instantly.
What is a picomole?
Picomole (pmol) is a unit of chemistry.
What is a femtomole?
Femtomole (fmol) is a unit of chemistry.
Is the picomole to femtomole conversion exact?
Yes. Both picomole and femtomole are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
What's the difference between mass concentration and molarity?
Mass concentration expresses how much mass of a substance is present per unit volume (for example, grams per liter). Molarity expresses the amount in moles per liter instead, which accounts for the substance's molecular weight. This category converts mass-concentration units.
