About Converting Gigaliters to Cubic Gigameters
Gigaliter and Cubic Gigameter 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: Gigaliter is 1000000000 liter units, and cubic metric volume unit.
Formula
cubic gigameters = gigaliters × 1e-21
This factor comes from each unit's defined relationship to the category's base unit: 1 gigaliter equals 1000000 base units, and 1 cubic gigameter equals 1e+27 base units, so dividing one by the other gives the direct gigaliter-to-cubic gigameter factor of 1e-21.
Simple example
1 GL × 1e-21 = 1e-21 Gm3
1 gigaliter = 1e-21 cubic gigameters.
Real-world example
10 GL × 1e-21 = 1e-20 Gm3
10 gigaliters = 1e-20 cubic gigameters.
