Frequently asked questions
What is the source unit in this conversion?
The source unit is imperial gallons per year (imp gal/yr). The Imperial Gallon (imp gal) is a unit of volume. The Year (yr) 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 year to cubic kilometers per year?
Multiply the imperial gallons per year value by 4.54609e-12 to get cubic kilometers per year. For example, 10 imp gal/yr × 4.54609e-12 = 4.54609e-11 km3/yr.
Is the imperial gallons per year 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 year?

About this conversion
This page converts imperial gallons per year (imp gal/yr) into cubic kilometers per year (km3/yr), two units of volumetric flow rate.
The Imperial Gallon (imp gal) is a unit of volume. The Year (yr) 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/yr × 4.54609e-12, 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.
