The Uses of Gallons to Petaliters Conversion
The petaliter is a metric unit of volume built from the liter, and this conversion is most useful to anyone working within large-scale hydrology and freshwater studies.
Measuring Continental Freshwater Stores
Hydrologists tallying the freshwater held in major river basins or ice sheets, originally computed in gallons, convert those totals into petaliters for continental-scale reporting.
Tracking Groundwater Depletion
Researchers studying large aquifer systems that lose billions of gallons annually convert cumulative depletion figures into petaliters to express decades of loss in one readable number.
Estimating Lake System Volumes
Scientists calculating the combined volume of a chain of large lakes, first summed in gallons from individual surveys, use this conversion to express the total in petaliters.

Frequently Asked Questions
How many petaliters are in 1 gallon?
1 gallon equals approximately 3.78541e-15 PL, a figure useful for anyone working at the large-scale hydrology and freshwater studies scale.
How many gallons are in 1 petaliter?
1 petaliter equals approximately 2.64172e+14 gallons, which puts the size of a single petaliter into a more familiar unit.
Where does the petaliter actually get used?
The petaliter is a metric unit built from the standard liter by shifting the decimal point, and it shows up most often in large-scale hydrology and freshwater studies.
Is this based on the US gallon?
Yes, this converter uses the US liquid gallon (3.785411784 liters) rather than the larger UK imperial gallon, so results would shift slightly if you mean that unit instead.
