Why are conversion values from gallons to cubic kilometers so small?

Because a cubic kilometer represents an extremely large volume compared to a US gallon, the conversion coefficient is very small.

Can I use this converter for everyday liquid volumes?

This converter is mainly useful for scientific and large-scale volume comparisons rather than typical daily measurements.

What should I consider when converting between these units?

You should consider precision and possible rounding errors due to the large difference in scale between gallons and cubic kilometers.
