What exactly is a US gallon?

A US gallon is a volume measure defined as exactly 231 cubic inches, equivalent to 3.785411784 liters, and is primarily used in the United States.

What does a gigaliter measure?

A gigaliter equals 10^9 liters or 1,000,000 cubic meters, used to represent very large liquid volumes in scientific and industrial fields.

Why are conversion results often in scientific notation?

Because gigaliters represent extremely large volumes, converting small gallon amounts results in very small decimal numbers that are easier to express with scientific notation.
