About Converting Femtoliters to Yoctoliters
Femtoliter and Yoctoliter appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Specifically: Femtoliter is 1e-15 liter units, and yoctoliter is 1e-24 liter units.
Formula
yoctoliters = femtoliters × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 femtoliter equals 1e-18 base units, and 1 yoctoliter equals 1e-27 base units, so dividing one by the other gives the direct femtoliter-to-yoctoliter factor of 1000000000.
Simple example
1 fL × 1000000000 = 1,000,000,000 yL
1 femtoliter = 1,000,000,000 yoctoliters.
Real-world example
10 fL × 1000000000 = 10,000,000,000 yL
10 femtoliters = 10,000,000,000 yoctoliters.
