Frequently asked questions
What is the source unit in this conversion?
The source unit is imperial gallons per second (imp gal/s). The Imperial Gallon (imp gal) is a unit of volume. The Second (s) is a unit of time.
What is the destination unit in this conversion?
The destination unit is cubic kilometers per year (km3/yr). The Cubic Kilometer (km3) is a unit of volume. The Year (yr) is a unit of time.
How do I convert imperial gallons per second to cubic kilometers per year?
Multiply the imperial gallons per second value by 0.000143461 to get cubic kilometers per year. For example, 10 imp gal/s × 0.000143461 = 0.00143461 km3/yr.
Is the imperial gallons per second to cubic kilometers per year conversion exact?
It's exact under the SI-based volume and time definitions used here, since both units convert to cubic meters per second through fixed, non-rounded factors.
Where is this conversion commonly used?
Flow rate conversions like this are used in plumbing, HVAC, irrigation, chemical processing, fuel and water metering, and engineering flow calculations.
Can I convert cubic kilometers per year back to imperial gallons per second?
Yes. Divide the cubic kilometers per year value by 0.000143461 (or multiply by 6970.55) to get imperial gallons per second.

About this conversion
This page converts imperial gallons per second (imp gal/s) into cubic kilometers per year (km3/yr), two units of volumetric flow rate.
The Imperial Gallon (imp gal) is a unit of volume. The Second (s) is a unit of time.
The Cubic Kilometer (km3) is a unit of volume. The Year (yr) is a unit of time.
The formula is km3/yr = imp gal/s × 0.000143461, 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.
