About Converting Attoliters to Gigaliters
Attoliter and Gigaliter 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: Attoliter is 1e-18 liter units, and gigaliter is 1000000000 liter units.
Formula
gigaliters = attoliters × 1e-27
This factor comes from each unit's defined relationship to the category's base unit: 1 attoliter equals 1e-21 base units, and 1 gigaliter equals 1000000 base units, so dividing one by the other gives the direct attoliter-to-gigaliter factor of 1e-27.
Simple example
1 aL × 1e-27 = 1e-27 GL
1 attoliter = 1e-27 gigaliters.
Real-world example
10 aL × 1e-27 = 1e-26 GL
10 attoliters = 1e-26 gigaliters.
