Formula
picoliters = femtoliters × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtoliter equals 1e-18 base units, and 1 picoliter equals 1e-15 base units, so dividing one by the other gives the direct femtoliter-to-picoliter factor of 0.001.
Simple example
1 fL × 0.001 = 0.001 pL
1 femtoliter = 0.001 picoliters.
Real-world example
10 fL × 0.001 = 0.01 pL
10 femtoliters = 0.01 picoliters.
