About Converting Cubic Decimeters to Attoliters
Cubic Decimeter and Attoliter 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: Cubic metric volume unit, and attoliter is 1e-18 liter units.
Formula
attoliters = cubic decimeters × 1e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic decimeter equals 0.001 base units, and 1 attoliter equals 1e-21 base units, so dividing one by the other gives the direct cubic decimeter-to-attoliter factor of 1e+18.
Simple example
1 dm3 × 1e+18 = 1e+18 aL
1 cubic decimeter = 1e+18 attoliters.
Real-world example
10 dm3 × 1e+18 = 1e+19 aL
10 cubic decimeters = 1e+19 attoliters.
