About this conversion
This page converts cubic kilometers per year (km3/yr) into us gallons per second (gal/s), two units of volumetric flow rate.
The Cubic Kilometer (km3) is a unit of volume. The Year (yr) is a unit of time.
The US Gallon (gal) is a unit of volume. The Second (s) is a unit of time.
The formula is gal/s = km3/yr × 8371.28, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
