About this conversion
This page converts us quarts per year (qt/yr) into imperial gallons per year (imp gal/yr), two units of volumetric flow rate.
The US Quart (qt) is a unit of volume. The Year (yr) is a unit of time.
The Imperial Gallon (imp gal) is a unit of volume. The Year (yr) is a unit of time.
The formula is imp gal/yr = qt/yr × 0.208169, 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.
