What is one US gallon in liters?

One US gallon is defined as exactly 3.785411784 liters.

What does a petaliter measure?

A petaliter measures extremely large volumes, equal to 10^15 liters, often used for planetary or astrophysical volumes.

Why are the converted values so small?

Because the gallon (US) is a small unit relative to the petaliter, conversions produce very small decimal results.
