About Converting Femtomoles to Picomoles
Femtomole and Picomole 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: Femtomole is 1e-15 mole units, and picomole is 1e-12 mole units.
Formula
picomoles = femtomoles × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtomole equals 1e-15 base units, and 1 picomole equals 1e-12 base units, so dividing one by the other gives the direct femtomole-to-picomole factor of 0.001.
Simple example
1 fmol × 0.001 = 0.001 pmol
1 femtomole = 0.001 picomoles.
Real-world example
100 fmol × 0.001 = 0.1 pmol
100 femtomoles = 0.1 picomoles.

Reverse conversion: Picomole to Femtomole
0.001 pmol × 1000 = 1 fmol
0.001 picomoles = 1 femtomole.
femtomoles = picomoles × 1000

Frequently asked questions
How many picomoles are in 1 femtomole?
1 femtomole equals 0.001 picomoles, using the exact defined conversion factor rather than an estimate.
How do I convert femtomole to picomole?
Multiply the femtomole value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert picomole back to femtomole?
Use the reverse factor: 1 picomole equals 1,000 femtomoles. You can also use the swap control in the converter above to flip the direction instantly.
What is a femtomole?
Femtomole (fmol) is a unit of chemistry.
What is a picomole?
Picomole (pmol) is a unit of chemistry.
Is the femtomole to picomole conversion exact?
Yes. Both femtomole and picomole are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
